Electrically conducting PET film was prepared by introducing amide group or cyano group into the PET film and then subjecting Cu
xS, which is known as the p-type semiconductor, into the grafted PET film. The effect of emulsifier on grafting of acrylamide on PET film was investigated and optimum conditions for the introducing of Cu
xS (ICuSO
4) 30 g/l, reaction time 3hrs) was studied. The Cu
xS-induced electrical conductivity of PET film was higher by order of 10
-13 than that of the original PET film. Using recently developed FT-IR, trans-gauche configuration was investigated. From energy dispersion X-ray analysis, Cu/S of Cu
xS-induced PET film was calculated. The morphology of Cu
xS-induced PET film surface was investigated with SEM.
