In this study, the surface hydrophilicity changes of PADC due to exposing by ArF laser with 50-500 mJ/cm2 fluences and up to 3000 shots was investigated. It was shown that wettability of the surface is dependent on total irradiated dose such that, the hydrophilicity initially decreases with increasing of the energy dose up to 50 J/cm2 and then, increases at higher doses. The value of contact angle variation for 500 mJ/cm2 fluence is about 2 times greater than that was observed at 50 mJ/cm2 case. The morphology and chemical results depict that laser-induced surface roughness is the dominant parameter for increasing hydrophilicity on exposed PADC.
Keywords: ArF laser, Chemical structure, Hydrophilicity, Laser-polymer interaction, Morphology, PADC.
