摘要： 合成了一种疏水缔合水溶性聚丙烯酰胺共聚物,使用荧光光谱法并结合紫外及流变性实验,对制备的疏水缔合水溶性聚丙烯酰胺共聚物在水溶液中形成疏水微区、超分子聚集体及空间网络结构进行了研究,并用扫描电子显微镜证实了溶液中网络结构的存在.

Abstract: A hydrophobically modified polyacrylamide P(AM/2-EHA) was synthesized. By means of viscosity measurements, fluorescence, UV spectra, and SEM, the hydrophobic association properties of P (AM/2-EHA) in aqueous solution were studied. The results show that with the increase of P (AM/2-EHA) concentration, hydrophobic domain, super-molecular aggregate and even space network structure can be formed in the solution by the hydrophobic association of P (AM/2-EHA). And SEM analysis verified the formation of network microstructure.

Key words: hydrophobically modified polyacrylamide, solution properties, microstructure, hydrophobic association
