CCl4等离子体表面改性聚三甲硅基丙炔膜

摘要/Abstract

摘要： 聚三甲硅基丙炔((PTMSP)具有优异的气体透过性,但其氧氮选择性差,可用等离子体改性等方法予以改进.

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
