通过原位溶液聚合法制备聚丙烯酰胺/2-丙烯酰胺-2-甲基丙磺酸/氧化石墨烯(PAM/AMPS/GO)纳米复合水凝胶。采用X射线衍射和红外谱图对复合水凝胶的结构进行了表征,并研究pH对水凝胶的染料吸附性能的影响。结果表明:GO与聚合物基体间存在较强的相互作用,能够均匀的分散在基体中。另外,复合水凝胶在中性溶液中对亚甲基蓝染料的吸附效果最佳,且最快达到吸附平衡。
Polyacrylamide / 2-acrylamide-2-methylpropanesulfonic acid / graphene oxide (PAM / AMPS / GO) nanocomposite hydrogel was prepared by in-situ solution polymerization. The structure of the composite hydrogel was characterized by X-ray diffraction and infrared spectroscopy. The effect of pH on the dye adsorption of hydrogel was also studied. The results show that there is a strong interaction between GO and the polymer matrix, which can be uniformly dispersed in the matrix. In addition, the composite hydrogel in the neutral solution of methylene blue dye adsorption best, and the fastest adsorption equilibrium.
