摘要
系统地论述了一类新型功能液晶高聚物———液晶聚磷腈的合成、结晶结构、液晶性质、熔体流变性能、气体分离及渗透汽化性能等.重点讨论了侧链烷基结构对结晶结构、液晶性质和气体分离性能的影响,指出液晶聚磷腈具有显著的液晶性、良好的气体分离能力和有机物/水、有机物/有机物的渗透汽化分离能力.
A review with 14 references on the synthesis, crystalline structure, liquid crystallinity, melt rheological behavior, gas separation and pervaporation properties of a new type of functional liquid crystalline polymer polyphosphazene is presented. The effect of the side groups of the polyphos phazene on the crystalline structure, liquid crystallinity and gas separation properties is discussed. It is suggested that the polyphosphazene membrane exhibits good gas separation and organic aqueous pervaporation capabilities.
