In this study, poly(ethylene terephthalate) (PET) film was treated with oxy fluorination, silane, and direct fluorination for surface modification of PET film. We measured the change of surface modified PET film surface characteristics using contact angle, surface free energy, FE-SEM, and XPS. After oxy fluorination, silane treatment, and direct fluorination, the water contact angle was measured to be 73.96o, 156% increase compared to the untreated PET film. Total surface free energy has been measured to be 47.22 mNm-1, 14.6% decrease compared to the untreated PET film. From this result, it was suggested that the oxy fluorination-silane treatment-direct fluorination process could be useful to make PET film surface hydrophobic. |
