Effect of Plasma Treatment on Surface Properties of Polymeric Membrane

In the present work the effect of plasma treatment has been used to improve the surface properties of polymeric membranes. The polymeric membranes of polycarbonate (PC) were synthesized using solution cast method. The plasma treatment was done in high vacuum chamber using nitrogen gas and the pressure for the plasma treatment was » 10-2 mbar. The effect of plasma treatment on surface properties like morphology, roughness, wettability and optical properties has been characterized using optical microscopy and UV-Vis spectroscopy for different time of plasma treatment.
