摘要

本論文研究之無機-有機結構體可提供新功能表面處理並且應用在軟性基板上。實驗中利用Aluminum tri-sec butylate (ATSB)與Ethyl acetoacetate (EtAc)螯合並且和3-Glycidoxypropyl-trimethoxysilane (GLYMO)以溶膠-凝膠化學作用製備無機有機混合物，研究以不同ATSB與GLYMO莫耳比與水解時間影響乾膜的性質。結果顯示膜硬度特性與反應物莫耳比在適當比例下與水解時間呈現正相關。在較長的水解時間條件下，乾膜的最高硬度可達6H，最低為HB。在極端莫耳比例下，膜硬度特性與水解時間無關。顯示莫耳比與水解時間都會影響乾膜性質。

Hybrid polymers with inorganic and organic structural units can be used to generate new functionalized coatings on a variety of substrates (ceramics, metals, polymers, etc.). Sol-gel process were mainly based on simple, readily available precursors, the high potential of new precursors chemically tailored for special applications is more and more realized. In this study, ethyl acetoacetate (EtAc) chelated Aluminum tri-sec butylate (ATSB) and 3-Glycidoxypropyl-trimethoxysilane (GLYMO) were used to prepare films of intermediate hardness by the sol-gel technique. With appropriate molar ratio, it was shown that the hardness of the cured film was shown to be associated with the molar ratio of the reactants and hydrolysis time A hardness as high as 6H was obtained in cases where a longer hydrolysis time was employed. However, with extreme molar ratios, the hardness is independent of hydrolysis time.
