Abstract: Effect of high frequency air discharge plasma on the surface and adhesion performance of polyethylene terephthalate (PET) substrates of different thickness was investigated. Based upon X-ray photoelectron spectroscopy, contact angle measurements and ATF FTIR was shown that chemical composition of thin surface layer changes even after first 5 minutes of plasma treatment in spite of mild conditions of etching. Structure changes were estimated by AFM and TEM. It was shown that plasma treatment reveals phase structure organization of PET, but total surface relief changes insignificantly. Dramatic change in surface energy after treatment was revealed by contact angle measurements. At the same time, it was shown that surface energy relaxation occurs during storage of substrate in room conditions. These results are in good agreement with adhesion performance of PET substrate to model silicon scotch estimated by 180ยบ Peel Test.
Keywords: surface energy, adhesion properties, plasma etching of pet surface
