Abstract

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.
