In this paper the effect of ArF laser irradiation on hydrophilicity of a Polyethersulfone membrane is investigated. The results show that, irradiation with 1000 and 2000 pulses at a fluence of 10 mJ/cm2 leads to decreasing the contact angle of water on the surface and then increasing the hydrophilicity
