| Abstract: | A soluble fluoropolymer poly(perfluoroctanoyloxyl-propyl methylacrylate) (PFPMA) was prepared using free radical polymerization. The structure and thormo-properties of PFPMA were characterized using FTIR, XRD, XPS, DSC and TG/DTA analyses. The surface properties of PFPMA films were determined by contact angle measurements and the surface free energy was calculated by using the data of contact angles. The results show that the surface free energy of the PFPMA film is as low as 14.2*!mN/m, and its contact angles are 115° and 75° for water and hexadecane,respectively. |
