Abstract
Poly (ethylene terephthalate) (PET) is one of the common polymers used widely in medical applications. However, its surface properties cannot meet the needs in many applications. Hence, the surface chemical and physical properties must be modified. In this work, water plasma immersion ion implantation (PIII) was employed to modify poly (ethylene terephthalate) (PET) to enhance oxygen-containing surface functional groups such as, -COOH, -C=O, -0-H. The modified surfaces were characterized by X-ray photoelectron spectroscopy (XPS), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), contact angle measurements, and scanning electron microscopy (SEM). At the same time, comparison of oxygen and water plasma for PET modification was carried out. Our experimental results show that water PIII can greatly improve the O to C ratios on the surface. Different processing conditions affect distribution of all the oxygen-containing functional groups. The surface hydrophilicity and morphology of the plasma-implanted PET were also investigated. Our results indicate that H2O Pm increases the surface hydrophilicity of PET significantly while the surface topography does not change.
