Three silicon compounds, dimethyldimethoxysilane (DMDMOS), decamethylcyclo-pentasiloxane (DMCPS), and 1,1,3,3-tetramethyldisiloxane (TMDSO), were plasma-poly-merized, and the solubility coefficient and the permeation coefficient of carbon dioxide and nitrogen gas were determined. The permeation properties of the deposited films were discussed. The plasma polymers formed from DMDMOS, DMCPS, and TMDSO showed pre-ferential solubility for carbon dioxide. The solubility coefficient of carbon dioxide was closely related to the concentration of Si-(O-)_4 moieties in the plasma polymers. However, these plasma polymers showed no selective permeation of carbon dioxide. The diffusion process rather than the solution process controlled the permeation of carbon dioxide across the plasma polymers. Plasma polymers formed from silicon compounds, if the polymers have less cross-linkage, are expected to be a good material for CO_2-selective membrane.

用等离子体聚合法合成了二甲基二甲氧基硅烷（DMDMOS）、十甲基环五硅氧烷（DMCPS）和1，1，3，3-四甲基二硅氧烷（TMDSO）三种硅化合物，测定了它们的溶解系数和二氧化碳、氮气的渗透系数。讨论了沉积膜的渗透性能。由DMDMOS、DMCPS和TMDSO形成的等离子体聚合物显示出对二氧化碳的优先溶解性。二氧化碳的溶解系数与等离子体聚合物中Si-（O-）_4基团的浓度密切相关。然而，这些等离子体聚合物没有显示出二氧化碳的选择性渗透。扩散过程而不是溶液过程控制二氧化碳穿过等离子体聚合物的渗透。由硅化合物形成的等离子体聚合物，如果其交联程度较低，可望成为一种良好的CO_2选择性膜材料。
