研究了在非离子表面活性剂 C9PE10 存在下制备的聚（N-异丙基丙烯酰胺）凝胶的收缩动力学。含有超过 6 wt.% C9PE10 的凝胶的收缩率增加了约一千倍。从收缩过程和小角X射线散射曲线的分析来看，快速收缩动力学归因于网络结构空间异质性的结合，这是由表面活性剂的添加引起的。
Shrinking kinetics of poly(N-isopropylacrylamide) gels prepared in the presence of a nonionic surfactant C9PE10 was investigated. The shrinking rate of the gels containing more than 6 wt.% of C9PE10 showed about a thousand-fold increase. From the analysis of the shrinking process and the small-angle X-ray scattering profiles, the fast shrinking kinetics was attributed to the incorporation of spatial heterogeneity of the network structure, which is caused by the addition of the surfactant.
