Abstract

Poly(ethylene terephthalate glycol) (PETG) sheets were irradiated using oxygen plasma produced in the reactive ion etching configuration of BSET EQ NT-1 plasma device. The samples were characterized using contact angle measurements, Fourier Transform Infrared Spectroscopy (FTIR), and profilometry. A decrease in contact angle was observed for the treated samples and a direct relation between power and wettability was noted. The profilometry results showed a general increase in surface roughness for the treated samples. At 200 W, the samples obtained the highest increase in surface roughness. FTIR results showed changes in the transmission for the treated samples but no chemical bonds were formed or broken.
