  • Acidic fluorine-containing poly (siloxane amideimide) silica hybrids
    Patent number: 6815519
    Abstract: 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.

  • Hydroxyl-containing fluorinated ooly (siloxane amideimide)
    Publication number: 20030187175
    Abstract: A hydroxyl-containing fluorinated poly(siloxane amideimide) is composed mainly of a hydroxyl-containing fluorinated polyamideimide portion formed by the reaction of a fluorinated dianhydride and a hydroxyl-containing fluorinated diamine, and a flexible siloxane-containing fluorinated polyimide portion formed by the reaction of a fluorinated dianhydride and a siloxane diamine. Said hydroxyl-containing fluorinated poly(siloxane amideimide) can be used as a surface acoustics wave (SAW) coating.
