Polymers with fluorinated side groups have attracted much attention due to their unique properties, such as high chemical and thermal stability, low surface free energy, and outstanding biocompatibility. Therefore, fluoropolymers are used prevalently in functional coating, textile finishing, and aeronautics and astronautics industries. The relationship between the structures of fluorinated polymers (including the structures of the main chains, the perfluorinated alkyl groups, and the spacer groups between them) and their surface properties is reviewed in this paper. Finally, the research progress of environmentally friendly low surface energy polymers with fluorinated side groups is introduced.
