摘要:
为了研究氧化石墨烯(GO)对海藻酸钠(SA)凝胶性能的影响,以Ca2+与Fe3+作为交联剂,在SA水凝胶自组装过程中加入GO水溶液,一步法得到了海藻酸钠/氧化石墨烯(SA/GO)复合水凝胶。通过扫描电子显微镜与X射线衍射表征了所得凝胶的结构与微观形貌,测试了不同凝胶样品的平衡溶胀性能和力学性能。研究结果表明,Fe3+交联得到的凝胶结构相比Ca2+交联得到的凝胶更加紧凑,平衡溶胀性能降低较多;随着GO的加入,复合水凝胶的力学性能提升,平衡溶胀性能降低,这表明SA/GO复合水凝胶的性能可以通过选择合适的交联剂与GO用量进行调控。关键词:海藻酸钠;氧化石墨烯;复合水凝胶
Abstract:
To study the effect of graphene oxide(GO) on the property of sodium alginate(SA) hydrogel,the sodium alginate/graphene oxide(SA/GO) composite hydrogel was prepared through the addition of GO in the self-assembly process of SA hydrogel using Ca2+ or Fe3+ as crosslinking agents. The morphology and structure of the as-prepared hydrogels were characterized by scanning electron microscopy and X-ray diffraction, and their equilibrium swelling degree and mechanical strength were also measured. The experimental results show that the equilibrium swelling degree of the hydrogel crosslinked by Fe3+ is significantly decreased with more compacted microstructure,compared with that of the hydrogel crosslinked by Ca2+. The mechanical strength of the composite hydrogel improves and the equilibrium swelling degree decreases with the increase of GO,indicating that the property of SA/GO composite hydrogel can be controlled with crosslinking agent and amount of GO.
