摘要： The present invention discloses an acidic fluorine-containing hybrid having a uniform distribution of an organic and an inorganic components prepared by a sol-gel process. The organic component is a fluorine-containing poly(siloxane amideimide) having a good processing ability, gas permeability, mechanical properties, and chemical stability. The inorganic component is silica having good heat resistance and moisture resistance. The hybrid has excellent properties, such as a good film formation property, a high gas selectivity, a low dielectric constant, a good resistance to scraping, and a good transparency, etc., and can be used in making industrial products, such as gas detection films, sensors, encapsulation material, photoelectrical communication material, and biomedical material, etc.

摘要： In the present invention, vinylimidazole and [3-(methacryloxy)propyl]trimethoxysilane are copolymerized to form a modified polyvinylimidazole, which then undergoes hydrolysis and condensation reactions with water and tetramethoxysilane to prepare a hybrid of polyvinylimidazole and silica. Experimental analyses show that covalent bondings exist between the modified polyvinylimidazole and silica in the hybrid.
