在新的气体分离膜材料中,聚1-三甲硅基丙炔(PTMSP)以其高的气体透过性和优异的成超薄膜性而引起各方面的兴趣。目前的研究热点是如何提高PTMSP的氧氮透过分离系数(ao_2/N_2)和气体透过稳定性。Langsam用氮稀释的氟气对PTMSP膜进行表面氟化处理,大幅度地提高了膜的ao_2/N_2,但处理过程中伴随着剧烈的裂解,控制困难。Gozds以N-溴代丁
Among the new gas separation membrane materials, poly-1-trimethylsilylpropyne (PTMSP) has drawn interest in various fields due to its high gas permeability and excellent ultra-thin film properties. The current research focuses on how to improve the oxygen and nitrogen transmission separation coefficient (ao_2 / N_2) and gas permeation stability of PTMSP. Langsam fluoridated with nitrogen gas to PTMSP membrane surface fluoridation treatment, ao_2 / N_2 membrane greatly improved, but accompanied by severe cracking process, control difficult.
