摘要
膜材料中迄今以聚三甲基硅基丙炔(PTMSP)的透气速率最大,其氧透过速率比PDMS高一个数量级,但氧氮分离系数小,透气性不稳定。改性PTMSP,以提高其透气选择性和透气速率稳定性引起人们的极大关注。本文报道,在外极管式电容耦合反应器中,
PTMSP membranes were modified by plasma technigue in the presence of hexamethyldisiloxane.The oxygen permeation rate Po_2 and oxygen-nitrogen separation coefficient α_(O_2)/N_2 of the modified membranes were 1590 barrer and 3.16, respectively.
