Abstract

In this research, the synthesis and swelling behavior of a hydrogel nanocomposite based on acrylamide, graphene oxide and polypopamine have been investigated. The synthesis was performed by grafting with optimal values to achieve a hydrogel with high water absorption swelling capacity. The polymerization reaction was performed in an aqueous medium in the presence of an ammonium persulfate initiator and methylene bisacrylamide crosslinker. The mechanism was proposed for the formation of hydrogels and its structure was confirmed by FTIR, XRD and SEM devices. The results obtained from water absorption and its swelling values in buffer solutions shown the synthesized hydrogels have high absorption capacity.

摘要

在这项研究中，研究了基于丙烯酰胺、氧化石墨烯和多巴胺的水凝胶纳米复合材料的合成和溶胀行为。该合成通过以最佳值接枝来实现具有高吸水膨胀能力的水凝胶。聚合反应在水性介质中在过硫酸铵引发剂和亚甲基双丙烯酰胺交联剂的存在下进行。提出了水凝胶的形成机理，并通过FTIR、XRD和SEM装置证实了其结构。吸水率及其在缓冲溶液中的溶胀值的结果表明，合成的水凝胶具有很高的吸收能力。
