摘      要： 通过激光光散射仪和扫描电镜对两亲聚合物（AP）溶液微观形态进行了研究，结合界面张力仪和流变仪对两亲聚合物性能进行了探讨。结果表明，AP溶液的临界胶束浓度（CMC）为1 000 mg·L-1，当AP溶液浓度低于CMC时，溶液中自由链与单分子胶束发生聚集交联，形成具有一定网络结构的单分子胶束聚集体，使AP溶液表现出以弹性为主的特征;当AP溶液浓度高于CMC时，溶液中会形成多分子胶束以及胶束的聚集体，随着AP溶液浓度的增加，多分子胶束和胶束的聚集体交联成了超分子结构的空间网络。AP溶液对油-水界面张力的降低最低可达10 mN·m-1左右 。

Abstract： The microscopic morphology of the amphiphilic polymer （AP） solution was studied by laser light scattering and scanning electron microscopy. The characteristics of the amphiphilic polymer were investigated by means of interfacial tension meter and rheometer. The results indicated that the critical micelle concentration （CMC） of AP solution was 1 000 mg·L-1. When the concentration of AP solution was lower than CMC， the free chains in the solution aggregated and crosslinked with the monomolecular micelles to form monomolecular micelles aggregates with a certain network structure， which made the AP solution show the characteristics of elasticity; when the AP solution concentration was higher than CMC， multi-molecule micelles and micelle aggregates were formed in the solution. With the increase of the concentration of AP solution
， the multi-molecular micelles and micellar aggregates crosslinked into supramolecular networks. The AP solution reduced the oil-water inter
