摘要: 水蒸气作为一种可凝聚性气体,导致它在高分子膜中的渗透行为比其它非凝聚性气体复杂。简要综述了水蒸气分子在高分子膜中的溶解和扩散行为,在不同的水蒸气活度下,考察了水蒸气在高分子膜中的溶解系数、扩散系数和渗透系数。分析了水分子与膜之间的相互作用,及水分子的成簇机理。Abstract: As a condensable gas,the water vapor permeates through membranes become more complicated than non-condensable gases.The solubility and diffusion behaviors of water vapor in polymer films are reviewed.Under the different water vapor activities,the solubili
