摘　　要：倒浮萍聚合物ＬＢ膜的有序－无序相变研究李宏斌，张希，张瑞丰，赵冰，徐尉青，沈家骢，高忠民（吉林大学分子光谱与分子结构开放实验室、化学系，分析测试中心，长春，１３００２３）关键词聚合物ＬＢ膜，有序－无序相变，变温红外光谱，变温小角Ｘ光衍射ＬＢ膜的有序－...The order-disorder transition in“Reversed Duckweed”type polymeric LB filmwas investigated by temperature-dependent infrared transmition and X-rav diffraction. Threesteps of melting process were obtserved :the first and second steps were reversible transitionscorresponding to the disorder of the alkyl chains in each layer,and the layer structure wasmaintained;the third was an irreversible transition corresponding to the melting of the two-dimension system,and the layer structure was damaged during this phase transition process.

关 键 词：聚合物 LB膜 有序-无序相变 红外光谱
