摘要： 聚1-三甲硅基丙炔膜经紫外线辐照后其氧氮选择性提高,用XPS及水接触角法研究了膜的表面组成对透气性的影响。

关键词: 聚1－三甲硅基丙炔, 紫外辐照, 透气性, 膜

Abstract: rradiation of the PTMSP homogeneous membranes by UV light(253.7nm)in air caused Oxidation of the membrane surface,elimination of -Si(CH3)3 and a-CH3 groups and degradation,The UV irradiated PTMSP membranes exhibit a higher hydrophilicity and better gas permeation properties with gas selectivity being improved. The oxygen-nitrogen separation coefficient ao2/N2 increased from l.5 to 4.7, but the oxygen permeation coefficient Po2 decreased from 8600 to 340 barrer.

Key words: PTMSP, UV irradiation, gas permeability, membrane
