摘要
利用Ｌａｎｇｍｕｉｒ膜天平－“面膨胀计”研究二维状态下的聚合反应具有两个方面的意义，即一方面通过高分子化制备聚合的单分子膜和ＬＢ膜，克服膜的力学强度低、耐热和耐介质性能差的缺点，使之实用化；另一方面通过ＬＢ技术实现分子的有目的组合来合成全新品种的聚合物，为设计新一代高分子的超分子结构以及研究低维状态下的聚合反应开辟新路径。文中详细介绍了近年来这一研究领域的发展状况，包括温度、表面压和亚相ｐＨ值等因素对二维聚合反应的影响以及聚合反应动力学参数的定量测定等。
It is of great significance in two respects that langmuir trough—? 穉rea dilatometry' is used as a probe to study polymerization reactions restricted to two dimensions: First, preparation of polymerized monolayers and LB films by means of preparation, in order to overcome their disadvantages of lower thermal and mechanical stability and putting them in application. Second, synthetizing a new generation of polymer with allowances for designing the superstructures of the polymer and investigating the polymerization reaction in low dimensions with LB technique. Recent advance in this research field was reviewed, including the effect of temperature, surface pressure, the pH of subphase and others on preparation reaction in two dimensions and the quantitative measurement of reaction kinetic parameters.
