Abstract

Abstract: Poly(ethylene terephthalate) (PET) substrates was prepared using 1,2-epoxypropane and CO2 by plasma polyreaction. FT-IR showed that a kind of organic polymer barrier to oxygen was formed. The oxygen barrier properties were investigated by Gas Permeability Tester. Plasma discharge power, working pressure and discharge time can affect oxygen barrier properties of PET film. The results show that the oxygen barrier properties increased and then decreased with plasma discharge power and working pressure, and increased with discharge time.

Key words: surface treatment, plasma, poly(ethylene terephthalate), film, oxygen resistance
