Preparation and Characterization of Fluorinated Organic/Inorganic Composite Particles

Abstract

Fluorinated organic/inorganic composite pariticles is synthesized by compounding aminosilane (N-beta-aminoethyl)-gamma-aminopropyl trimethoxy silane or N-(beta-aminoethyl)- gamma-aminopropyl methyldimethoxy silane and perfluorinated octyl sulfonic acid fluoride. The structure and properties of products are characterized by FTIR , 1 HNMR, TG/DTA, Mastersizer analysis and contact angle, the synthesized product shows good thermal resistance, and its particle size is in the micrometer- level, surface water contact angle is 116deg.
