Surface modification of polyethylene and polypropylene in low-pressure plasma and in atmospheric pressure plasma-solution system

摘要

The effects of polyethylene (PE) and polypropylene (PP) surface modification in low-pressurernplasma and in a plasma-solution system at atmospheric pressure were compared in this study.rnSurface of PE and PP was characterized by contact angle measurements followed by surface freernenergy calculation, Fourier Transform Infrared by Attenuated Total Reflectance (FTIR-ATR),rnXPS and AFM methods. Surface modification in both types of plasma systems results in thernsurface oxidation, improves polymer wettability and allows the grafting of poly(acrylamide) tornactivated surface.
