摘要： 对聚三甲硅基丙炔(PTMSP)进行表面氟化改性,改性膜的氧氮选择性提高,气体透过稳定性增加。用XPS谱分析改性后的膜表面,其表面结构发生了显着变化。

关键词: 聚三甲硅基丙炔, 氟化改性, 气体透过性, 氧, 氮

Abstract: Poly[1-(trimethylsilyl)-1-propyne] membranes were modified with fluorine gas. The fluorinated membranes exhibited good gas permeation properties and a significant increase in gas selectivity over the unfluorinated PTMSP membranes.The oxygen-nitrogen separation coefficient αo2/N2 increased from 1.5 to 4.75,the oxygen permeation coefficients Po2 decreased from 8600 to 370 barrier, and the constancy of gas permeabitily of the membranes was improved.

Key words: polytrimethylsilylpropyne, modification by fluorine, oxygen nitrogen permeability
