Abstract: Polyethylene terephthalate (PET) films were pretreated with oxygen plasma firstly. Then, polypyrrole (PPy) functional layers were polymerized on the surface of PET films to form PET-PPy composite films by in situ chemical oxidation polymerization method. Atomic force microscopy, X-ray photoelectron spectroscopy and zeta potential measurement were used to characterize PET films pretreated with oxygen plasma for different durations. The surface morphology and electrical resistance of PET-PPy composite films before and after abrasion were investigated by scanning electron microscopy, abrasion resistance and sheet resistance measurements. The results showed that the interfacial adhesion of PPy functional layer to PET film is significantly improved by oxygen plasma pretreatment. The increased surface roughness and the enhanced electronegativity are the leading factors for the improved adhesion strength. In addition, the optimal pretreatment duration is 120 s.
