摘要

The surface of polymeric membranes was modified by plasma treatment using Ar, NH_3. Permeabilities for CO_2, N_2 and separation factor for CO_2 relative to N_2 were measured. The effects of the plasma conditions such as treatment time, power input, gas flow rate and pressure in the reactor on the transport properties of modified membrane were investigated. The surface of the plasma treated membranes was analyzed by means of FTIR-ATR, AFM and Contact angle. The surface of the plasma treated fairly different from that of the untreated membrane, Although the separation factor decreased with increasing plasma treatment time, the separation factor was improved by the plasma treatment. So the operating conditions of plasma treatment effect on the permeability and separation factor.
