摘要 对芳香聚酰胺、聚砜酰胺、聚苯并咪唑酮、聚砜和醋酸纤维等五种膜材料进行差热扫描量热研究,发现膜在室温下结合水和脱除水是一平衡,升温后水游离出来,回到室温时又结合上去,若在高温时移至液氮中骤冷,膜表面结合部分多分子水,此时膜和水的热性能和结合单分子水为主的膜明显不同。 The states of absorbed water on some membranes were further studied by DSC. The absorption and desorption of water on membranes was an equilibrium. Water Was desorped when temperature increased, and was absorbed while returning to room temperature(Absorbed water oligomers were obtained when hot membranes were cabling in liquid nitron, .The thermal properties of membrane with water olikomers were different from those if membranes with momer mers.
