Inorganic-organic Hybrid Oxide Polymer and Manufacturing Method thereof

[0001] The present invention relates to an inorganic-organic hybrid oxide polymer and a manufacturing method thereof, in particular to a polymer based on a silicon titanium hybrid oxide and organic molecules and a manufacturing method thereof

[0002] In nowadays, the silica-titania hybrid film is widely applied in the optics field and usually acts as, for example, a high refractive index film, an optical waveguide component, an nonlinear optical material and various different kinds of optical protective layers. The conventional methods for manufacturing various silica-titania films include an evaporation scheme, a sputtering scheme, a chemical vapor deposition (CVD) scheme, a plasma enhanced chemical vapor deposition (PECVD) scheme, an atomic layer deposition (ALD) scheme and the like.

[0003] No matter which kind method is selected to manufacture the above-mentioned hybrid film, the uniformity issue of mixed silicon dioxide (SiO₂) and titanium dioxide (TiO₂) molecules and the issue how to ensure a good interfacial adhesion between the molecules will happen. Moreover, the vacuum systems are required of the embodiments of above mentioned methods which the processing equipment cost is relatively high, and the large-scale production is difficult. Furthermore, the coating ability of the vapor deposition or sputtering on a porous substrate is poor, and the disadvantages of chemical vapor deposition are high reaction temperatures and it will possibly damage the substrates.

[0004] For the aforementioned reasons, the synthetic ways to manufacture the hybrid films were gradually developed. One of it is to take advantage of a sol-gel reaction process and in conjunction with the appropriate organic molecular materials as the interfacial adhesion between the colloidal particles to prepare organic/inorganic polymer hybrid materials. The advantages of Sol-gel method are high purity, good chemical uniformity, easy to control the constituent ratio, able to be coated on large and complex substrate, the process is simple and the process temperature is low, the production dimensions is large, low manufacturing costs and cheap equipment that various aspects of advantages are applied to overcome present issues in conventional technology.

[0005] FIG. 1(a) to FIG. 1(c) show schematic diagrams respectively illustrating various mixing types regarding silica molecules and titania molecules in the silica/titania hybrid film in the prior art; FIG. 1(a) shows a mixed state that there is none of chemical bonds existing between SiO₂ molecules 10 and TiO₂ molecules 12 and the SiO₂ molecules 10 and TiO₂ molecules 12 exist in the film in a mixture state; FIG. 1(b) shows that SiO₂ molecules 10 and TiO₂ molecules 12 are bonded with each other through chemical bonds; and FIG. 1(c) shows that SiO₂ molecules 10 and TiO₂ molecules 12 are bonded with each other through the organic molecules 14 acting as interface adhesive substance.

[0006] However, whether it is a mixture of FIG. 1(a), the chemical bonding of FIG. 1(b) or the interfacial adhesion mixing state of FIG. 1(c), the colloidal particles cannot be stacked tightly issues are existing. The film surface is not fine-scale morphology under microscopic view, and the obvious defects of non-uniform structure and different chemical constitutions of the film need to be further improved.

[0007] There is a need to solve the above deficiencies/issues.

The polymer can be identified and confirmed to be an amorphous inorganic—organic polymer through the X-ray photoelectron spectroscopy (XPS) measure technology which has the formula of (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac), wherein x=0.2˜0.4, y=0.6˜0.8 and z/(x+y)=1.5˜1.9, and a preferable embodiment is (TiSi)_1.01O_1.84.

It is observed that dense film or porous film is both with strong Si—O—Ti bonds, but the dense film has more Si—O—Ti bonds than porous film.

[0035] FIG. 3(a) shows a molecular configuration for the (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) polymer in accordance with the present invention.

According to FIG. 4(a), an ultra-smooth surface of the dense film of the (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) polymer synthesized in the present invention can be seen, that is to say, the surface is relatively less rough and the surface roughness Ra<10 nm and has a very dense molecular structure. It is to be noticed that from FIG. 4(a) any small cracks or defects on the surface of the dense film was not observed; according to FIG. 4(b) and FIG. 4(c), the 2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) organic molecule is filled in the voids among (Ti_xSi_y)O_z inorganic molecule clusters, and only little voids remained in the (Ti_xSi_y)O_z inorganic molecule clusters which are filled by 2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) organic molecules, for the reason that the (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) polymer itself may have a relatively dense composition; according to FIG. 4(d), the porous film has a relatively rough surface and more coarse molecular structure.

[0037] According to the actual measuring the dense film of the present invention, the volume percentage of entire voids of the whole polymer is preferably between 0.01% to 1%, and the mean characteristics diameter size of the voids is between 0.2 nm˜30 nm, preferably between 0.5 nm˜20 nm. The receptive voids have a shape most close to circular but not circular that the mean characteristics diameter size of the voids is the diameter which regarded the voids as the nearest circle. The organic molecule 2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) filled in the voids among inorganic molecule clusters (Ti_xSi_y)O_z, in fact, can be further decomposed using high-temperature pyrolysis method after the film being formed, and then it eliminates from the inorganic molecule clusters (Ti_xSi_y)O_z that the pure inorganic molecule clusters (Ti_xSi_y)O_z, remains, in which the inorganic molecule clusters (Ti_xSi_y)O_z occupy more than 99% over the entire polymer; through actual measurements, the dense film in accordance with the present invention has a hardness equal to or greater than pencil hardness 9H.

[0038] In view of the titanium-silicon films are widely applied in the optics field, in the present embodiment, a spin-on coating technique of forming a 720 nm thickness single layer (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) polymer film on the quartz plate is further applied. The polymer films of dense film and porous film are produced individually and the thickness of both films are controlled to be between 500 nm˜800 nm to further measure the optical properties. FIG. 5 shows an AM1.5 solar spectrum for the (Ti_xSi_y)O_z/ 2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) polymer dense film in accordance with the present invention. According to FIG. 5, the hybrid oxide polymer film of the present invention, either dense film DN or porous film PO, has an average light transmittance of 98% in the wavelength range of 400 nm˜1,600 nm, and the dense film

[0039] DN has a better transmittance than porous PO film in the short wavelength (<400 nm) range.

[0040] FIG. 6(a) shows a plot diagram illustrating the refractive index n and extinction coefficient k with respect to the distance from the surface to the interface of the substrate for the dense film in accordance with the present invention. According to FIG. 6(a), the refractive index n and extinction coefficient k to the distance from the surface to the interface of the substrate distribution curve, in the film thickness of 670 nm and light wavelength 500 nm conditions, the film has a gradient refractive index which is lower at the end of air (approximately 1.6), higher at the end of the substrate (approximately 1.7) and can be controlled by the composition of titanium and silicon of the films. FIG. 6(b) shows a plot diagram illustrating the refractive index to the light wavelength for the dense film in accordance with the present invention. According to FIG. 6(b), under the conditions of the light wavelength greater than 400nm, the measured refractive index of the polymer film of the present invention is between 1.5˜1.7. In this embodiment, to find a better refractive index for the anti-reflective feature of present invention, can further adjust the proportion of Ti to Si in the (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) hybrid oxide polymer, i.e. adjusting the proportion of x to y, to adjust the refractive index of the (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) hybrid oxide polymer.

[0041] The porous film in accordance with the present invention can be used as the biocompatible substrate. FIG. 7 shows an image demonstrating the porous film acting as a biocompatible substrate in accordance with the present invention. A porous film made by the method in the present invention can be used as the biocompatible substrate, since its rough surface is particularly accommodated to the bio-cell growth. According to the image shown in FIG. 7, cells grow well on the surface of the porous film.

[0042] That is to say, the present embodiment made Ti, Si and O in the amorphous state completely bonding to each other to form an inorganic compound through the low-temperature Sol-gel process. The 2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) organic molecules are filled in the voids among the inorganic molecules, to form the (Ti_xSi_y)O_z/2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) inorganic-organic polymer finally, which is an compounded organic-inorganic polymer on the basis of hybrid oxide, wherein the 2,4-pentanedione (acetylacetone, entane-2,4-dione, acetylacetone, acac) is selectively decomposed to form the inorganic hybrid oxide clusters (Ti_xSi_y)O_z finally.

[0043] The manufacturing method as described in embodiment 1 is to be implemented, but silicon Si element is replaced by by iron (Fe) element. Finally the polymer of (Ti_xFe_y)O_z/organic molecules is synthesized. Through the X-ray photoelectron spectroscopy (XPS) measurement technique, the polymer of (Ti_xFe_y)O_z/organic molecules can be identified and confirmed as an amorphous inorganic-organic polymer which has the molecular formula of (Ti_xFe_y)O_z/organic molecules, wherein x=0.2˜0.4, y=0.6˜0.8 and z/(x+y)=1.5˜1.9, and a preferable embodiment is (TiFe)_2.99O_5.76/organic molecules, wherein the organic molecules can be removed by thermal-pyrolysis; FIG. 7 shows an image demonstrating the dense film structure of the (Ti_xFe_y)O_z/organic molecules polymer at the surface and the cutting edge in accordance with the present invention obtained by the observation of a scanning electron microscope. According to FIG. 7, an ultra-smooth surface of the dense film of the (Ti_xFe_y)O_z/organic molecules polymer synthesized in the present invention can also be seen, that is to say, the surface is relatively less rough and the surface roughness Ra<1.0 nm and has a very dense molecular structure, and any small cracks or defects on the surface of the dense film was not also observed.

[0044] The present invention is the implementation of forming a polymer of inorganic hybrid oxide (M_xN_yO_z and organic molecule cluster OG which is on the basis of the first element M and the second element N, wherein has the formula of (M_xN_y)O_z/OG, through the low-temperature hydrolysis polymerization reaction technology. The polymer is neither a conventional technology of the mixture of the oxide MO of the first element and the oxide NO of the second element, nor is it substances including different proportions of MO-NO mixtures and M-O-N bonds, that is to say, the content ratio of (M_xN_y)O_z inorganic molecule clusters of the present invention can be more than 99.9% over the entire polymer.

[0045] The inorganic-organic hybrid oxide polymer according to the present invention has the superior characteristics of both the organic and inorganic components, such as characteristics of high tensile modulus, scratch resistance, thermal stable, good dimensional stability and so on which an inorganic component owns, and characteristics of toughness, flexibility, lightweight and so on which an organic component owns. Although the polymer in the present invention is in an amorphous state, but still owns the form of fine-scale morphology owing to the reason the excellent optical characteristic through actual measurement it has.

[0046] The inorganic-organic hybrid film according to the present invention can be widely used in the field of optics, e.g., a high refractive index film, an optical waveguide component, a nonlinear optical material and various optical protective layers, and can be further used as biological composite materials, e.g. a biocompatible substrate.
