| 專利摘要 | 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. |
