Study on Surface Modification of Polyethylene Terephthalate(PET) Film by RF-Ar/O₂ Plasma Treatment

Abstract:

The surface of polyethylene terephthalate film was modified using RF- Ar/ O2 glow discharge plasma under the condition of Ar and O2 flow amount of 1.9 and 1.2 (L/min) respectively and treatment power of 60 W. The changes of the properties of the film before and after modification were analyzed and characterized with static contact angle measurement, X-ray photoelectron spectroscopy(XPS), atomic force microscopy(AFM), differential scanning calorimetry(DSC). The results showed that the hydrophile of PET film was improved obviously after modification and formed some polar groups such as C-N, N-C=O, C=O, etc. on the film surface; The surface roughness was increased and appeared conical or globular protuberances; the thermal behaviors (mainly crystallinity) were changed after treatment by RF- Ar/O2 plasma.
