Synthesis, Structure, Properties, and Applications of Fluorinated Polyurethane

Abstract

Fluorinated polyurethane (FPU) is a new kind of polyurethane (PU) material with great applicational potential, which is attributed to its high bond energy C-F bonds. Its unique low surface energy, excellent thermal stability, and chemical stability have attracted considerable research attention. FPU with targeted performance can be precisely synthesized through designing fluorochemicals as hard segments, soft segments, or additives and changes to the production process to satisfy the needs of coatings, clothing textiles, and the aerospace and biomedical industries for materials that are hydrophobic and that are resistant to weathering, heat, and flames and that have good biocompatibility. Here, the synthesis, structure, properties, and applications of FPU are comprehensively reviewed. The aims of this research are to shed light on the design scheme, synthesis method, structure, and properties of FPU synthesized from different kinds of fluorochemicals and their applications in different fields and the prospects for the future development of FPU.

Self-Organization of Polyurethane Ionomers Based on Organophosphorus-Branched Polyols

“…The properties of polyurethanes are controlled by changes in chain length, molecular weight, functionality, and the use of elements such as fluorine, phosphorus, etc. in the polyol chain [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Such a high degree of variability in the properties of polyurethane materials has ensured their popularity.…”
