项目摘要

The atmospheric pressure glow discharge (APG) plasma process would be advantageous ad regards, the cost of apparatus, treatment of large substrates and the continuous operation. We prepared the APG plasma reactor and demonstrated plasma treatment, plasma polymerization and plasma graft polymerization techniques using APG plasma.The surface of poly (dimethysiloxane) membrane was modified by the APG plasma treatment using He, and the CO_2 permeability and the selsctivity of CO_2 over CH_4 were investigated in detail. Permeance of CO_2 decreased monotomously with the increase of the APG plasma treatment time as in the case of the low pressure plasma treatment. CO_2 selectivity was much improved by the plasma treatment, and went well beyond the value of the untreated poly (dimethylsiloxane) membrane The selectivity could be well correlated with the structure of membrane surface and the affinity between CO_2 and the membrane surface was considered to increase by the existence of the polar groups such as C-OH.Polyethylene film was prepared by the APG plasma method onto the poly (dimethylsiloxane) membrane. Irrespective of the plasma exposing to C_2H_4 monomer, polyethylene film was polymerized. Therefore, polythylene film was considered to be deposited by the plasma-initiated polymerization.The cation-exchange membrane were prepared by grafting acrylic acid coated on the substrates such as microporous polythylene by the use of APG plasma graft polymerization technique. The gtafting method was peculiar to APG plasma. The grafted membrane was applied to the facilitated transport membrane using EDAH^+ as carrier of CO_2. The carrier was immobilized by the electrostatic force in the ion exchange membranes. The high CO_2 permeance and selectivity were obtained.
大气压辉光放电(APG)等离子体工艺在设备成本、大衬底的处理和连续操作方面将是有利的。我们制备了APG等离子体反应器,并演示了APG等离子体处理、等离子体聚合和等离子体接枝聚合技术。利用He进行APG等离子体处理对聚二甲基硅氧烷膜进行表面改性,详细研究了CO_2的渗透性以及CO_2对CH_4的选择性。与低压等离子体处理的情况一样,随着APG等离子体处理时间的增加,CO_2的渗透性单调下降。等离子体处理后CO_2选择性大大提高,远远超出未处理的聚二甲基硅氧烷膜的值。选择性与膜表面结构有很好的相关性,认为C-OH等极性基团的存在增加了CO_2与膜表面的亲和力。采用APG等离子体法在聚二甲基硅氧烷上制备了聚乙烯薄膜。 膜。无论暴露于C_2H_4单体的等离子体如何,聚乙烯膜都会聚合。因此,聚乙烯薄膜被认为是通过等离子体引发聚合沉积的。采用APG等离子体接枝聚合技术,将丙烯酸接枝到微孔聚乙烯等基材上,制备了阳离子交换膜。 gtafting 方法是 APG 等离子体所特有的。将接枝膜应用于以EDAH^+为CO_2载体的促进传输膜上。载体通过静电力固定在离子交换膜中。获得了较高的CO_2渗透性和选择性。
