Surface fluorination of conventional polymers can give them desirable surface properties similar to the expensive and difficult-to-process fluoropolymers.However,traditional surface fluorination tech-niques often require toxic reagents and special equipment.Here,we report a simple and effective poly-mer surface fluorination method by using safe and inexpensive perfluoro-2-methyl-3-pentanone(PFMP,C2F5C(=O)CF(CF3)2)and UV irradiation.This method is applicable to various polymer materials,and gen-erates nanometer-thick fluorinated layer on the outermost surface,significantly changing their surface properties without changing the surface morphology.
