摘要
利用气相色谱法研究了聚砜(PS)膜材料与71种有机物质的相互作用,获得了反映其相互作用强弱的热力学函数——溶解热和溶解自由能,并与其相溶性进行了关联,对铸膜液中有机添加剂的选择进行了尝试。结果表明,聚砜铸膜液体系有机添加剂多为具有较强的形成氢键能力的极性质子型有机物质。
The interaction between polysufone (PS) and 71 low molecular weight organic compounds with different functional groups have been studied by the gas-liquid chromatography (GLC). The free energy of solution and heat of solution of these compounds to PS polymer have been obtained, and the free energy of solution have been correlated to the selected organic additives in PS membrane casting solutions. The organic additives in PS membrane casting solution are mainly the polar proton compounds.
