Radiation from the UV excimer lasers can change the polymer surfaces morphology and chemical composition and affect their performance for different applications. In this study the effects of XeCl excimer laser irradiation on morphology of polyethersulfone membranes with different compositions of polyvinylpyrolidone (PVP) was investigated
