摘要: 用自由基引发苯乙烯-二乙烯基苯(St-DVB)共聚合成了带有大量乙烯基的活性微凝胶,再将此活性胶核与甲基丙烯酸(MMA)共聚制得微凝胶星型两性聚合物,并成功地制备了LB膜,此微凝胶星型两性聚合物LB膜与-般典型LB膜的区别在于它的疏水部分不是长脂链,而是分子量比较大的苯乙烯-二乙烯基苯微凝胶;此疏水的微凝胶核与亲水的聚甲基丙烯酸链在气-液界面上形成类似"浮萍"结构的单分子膜,因而在诸多方面表现出特异性质。

Abstract: The behavior of this new kind of star-shaped amphiphilic polymeric monomolecuar layer membrane was studied by the surface pressure-area(π-A) curves. It is found that the π-Acurves can be influenced by many factors such as the floating plate vertical or parallel to the compression direction, different diffusing time, and repeat compression times. We also studied stearic acid amphiphile plasticized the GPSMA monolayer.
