Research progress of perfluoropolyether polymers and functional composites

Perfluoropolyether (PFPE) polymers possess low surface energy, low friction coefficient, excellent lubricating properties and good hydrophobic-oleophobic properties. They are widely used as lubricating materials of the fields of aerospace, nuclear industry, vacuum equipment, electronics, etc. They are also used as reactive intermediates of the synthesis of many functional composites. Recently, PFPE-based functional composites have received extensive attention in several emerging fields. Firstly, the latest research progress of PFPE polymers in the lubrication field are introduced. The insufficiencies of corrosion resistance, anti-rust, and the PFPE base oils creep-resistant of PFPE lubricants are mainly expounded, and their reasons are analyzed. Then, the research progress and application prospect of PFPE polymers in the aspects of functional coatings, fluorine-containing polyurethanes, fluoroelastomers, and Vitrimers are summarized. Preparation processes of some fluorinated functional composites are introduced. Finally, the future trends on research and application of PFPE polymers are prospected in order to provide new ideas for widening the application field of PFPE polymers and developing high value-added PFPE derivatives.
