| Summary: | 碩士 === 元智大學 === 化學工程與材料科學學系 === 99 === The preparation of inorganic–organic hybrids based on the use of sol–gel chemistry offers a creative approach for synthesizing novel materials. Ethyl acetoacetate (EtAc) chelated Aluminum tri-sec butylate (ATSB) and mixed with 3-Glycidoxypropyl-trimethoxysilane (GLYMO) by the sol-gel technique. Inorganic segment can be obtained from ATSB and organic segment can be obtained from GLYMO. In this study, the effect of different GLYMO/ATSB molar ratio and hydrolysis time on the hardness and light transmittance of cured films were investigated in this study.
The result suggests that molar ratio of GLYMO/ATSB is the key factor in determining the hardness of the cured film. An optimal GLYMO/ATSB molar ratio exists that film hardness is independent of hydrolysis time. With a molar ratio of GLYMO/ATSB other than the optimal value, i.e. too low or too high, film hardness is a strong function of hardness. The trend of how hardness varies with hydrolysis time differs for different GLYMO/ATSB molar ratio.
