Abstract: Fluorinated quaternary ammonium salts are novel surfactants, which exhibit some unusual physico-chemical properties, such as high surface activity, high thermally chemical stability, hydro-oleophobicity. The synthesis methods of cationic fluorinated surfactants are reviewed and categorized according to the characteristics of different molecular structures. Especially the surfactants with some specific functions, such as diallyl, hydroxyl, gemini and amino groups, are presented. Their applications in phase transfer catalyst, supercritical carbon dioxide additive, metal corrosion inhibitor, foam extinguishing agent, textile finishing agent, and antibacterial agent are discussed. The current problems and developing trends of fluorinated quaternary ammonium surfactants are analyzed and prospected.

Key words: fluorinated quaternary ammonium salts, surfactants, textile finishing agent, foam extinguishing agent, fluorinated quaternary ammonium salts, surfactants, textile finishing agent, foam extinguishing agent
