Studies on hydrophilicity of poly(tetrafluoroethylene) film by remote argon plasma
In this article, the effects of surface modification on Poly(tetrafluoroethylene) (PTFE) are reported by remote argon plasma. The surface microstructures and compositions of the PTFE film were characterized with the contact angle meter, scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). After the remote argon treatments modified the morphology and composition of PTFE surface, modifications cause surface oxidation of PTFE films and form some polar functional groups which enhance polymer hydrophilicity. The contact angles of treated PTFE film decrease from the untreated 108° to 58°, the surface free energy increases from the untreated 22.1×10-5 N/cm to 47.2×10-5 N/cm. The hydrophilicity of the PTFE surface is greatly improved.
