An Investigation of the Surface Modification Mechanism on PET by Fluorocarbon Piasmas

Abstract

Abstract: Poly(ethyl terephthalate)(PET) surfaces were modified by CF₄ and CH₄/CF₄ plasmas in this paper. The angle-dependent X-ray photoelectron spectroscopy(XPS) technique was employed to determine the changes of surface structures and properties of the modified PET. The surface modification mechanisms on PETby the fluorocarbon plasmas at different molar ratios were detailed discussed. Experimental results show that hydrophobic characteristic of the modified PETsurface can be improved by fluorocarbon plasmas singnificantly. CH₄/CF₄ mixture plasma is polymerization predominated, and the homogeneity along depth of surface layers can be intuitively observed. On the other hand, pure CF₄ plasma is etching prodominated, and the fluorine-containing groups distributes on the modified PETsurface.
