摘　　要：采用自制的硅橡胶(PDMS)膜,研究了两组分混合溶剂在硅橡胶膜中的溶胀行为及分配系数.比较了溶胀率的实验值和理论值,考查了溶胀液平衡浓度与硅橡胶膜的溶胀率和分配系数的关系,以及溶胀液平衡温度与分配系数的关系.The swelling behavior and distribution coefficient of two components were investigated by using self-manufactured silicone rubber(polydimethylsiloxane(PDMS))membranes.The experimental values and theoretical ones of the swelling ratios were compared.The influence of equilibrium concentration and temperature of swelling solution on distribution coefficient was studied.The relationship between swelling ratios of silicone rubber membranes and distribution coefficient was discussed.
