以二甲基二乙氧基硅烷和正硅酸乙酯为前驱体，制备了厚度为30~500微米的溶胶-凝胶法自支撑薄膜。气相色谱和质谱分析表明，(CH3)(2)Si-O(N)分子是在水解和缩合过程中形成的。这种分子在凝胶网络中充当空间填充物，并提供薄膜的弹性。利用红外光谱和原子力显微镜对薄膜的结构和表面形貌进行了研究。(C)1999 Elsevier Science B.V.保留所有权利。
Sol-gel derived self-supporting films with thickness ranging from 30-500 mu m was prepared by using dimethyl-diethoxysilane and tetraethoxysilane precursors. Gas chromatography and mass spectrum analysis indicates that ((CH3)(2)Si-O)(n) molecules were formed during hydrolysis and condensation. Such molecules act as space filler within the gel network and provide the film flexibility. IR and AFM techniques were used for the film structure and surface morphology investigations.
