| Abstract: | Modification of poly(tetrafluoroethylene) (PTFE) films with 2-methacryloyloxyethyl phosphorylcholine (MPC) was performed by
low-temperature plasma treatment and grafting polymerization. Surface properties of PTFE were characterized by attenuated
total reflectance Fourier transform infrared (ATR-FTIR) spectra, X-ray photoelectron spectroscopy (XPS), and static contact
angle. The results show that MPC has been grafted onto PTFE film surface successfully. Contact angle for the modified PTFE
films in the water decreased from 108° to 58.25°, while surface energy increased from 17.52 mN/m to 45.47 mN/m. The effects
of plasma treatment time, monomer concentration and grafting time on degree of grafting were determined. In the meanwhile,
blood compatibility of the PTFE films was studied by checking thrombogenic time of blood plasma. |
