Abstract

Abstract: PTMSP membrane was modified by CCl₄ plasma, and the surface of modified membranes was studied by XPS and water contact angle measurements. The experimental results show that the CCl₄ plasma modified membranes exhibit a significant increase in gas selectivity over the unmodified PTMSP.The oxygen-nitrogen separation factorsαo₂/N₂ increased from 1.50 to 7.89 and the oxygen permeation coefficient Po₂ decreased from 9×10₅ Barrer to 9×10₂ Barrer.

Key words: polytrimethylsilylpropyne, plasma modification, oxygen-nitrogen selectivity
