Abstract
A series of UV-curable fluorinated polycarbonate polyurethanes (FCPUAs) were synthesized by modifying polycarbonate polyurethane with 2-(perfluorohexyl)ethanol (PFHE) and glycidyl methacrylate (GMA). The structures of FCPUAs were analyzed with 1H NMR and FTIR. Different contents of FCPUAs were blended into non-fluorinated polycarbonate polyurethane as fluorinated additives. The water and oil contact angles of the films were investigated by contact angle measurement, and the results indicated that an extremely low concentration of FCPUAs could produce a highly hydrophobic and oleophobic coating. The X-ray photoelectron spectroscopic analysis showed that the coating surface was rich in fluorinated species. Besides, the films containing FCPUAs also had great tensile strength, hardness and adhesion.
