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。
rradiation of the PTMSP homogeneous membranes by UV light(253.7nm)in aircaused Oxidation of the membrane surface,elimination of -Si(CH3)3 and a-CH3 groups anddegradation,The UV irradiated PTMSP membranes exhibit a higher hydrophilicity and bet-ter gas permeation properties with gas selectivity being improved. The oxygen-nitrogen sep-aration coefficient ao2/N2 increased from l. 5 to 4.7, but the oxygen permeation coefficient Po2decreased from 8600 to 340 barrer.
