采用原位聚合的方法制备碳纳米管/石墨烯杂化材料,透射电镜表征了该杂化材料的三维结构。通过碳纳米材料在乙醇溶液中的分散性实验,研究碳纳米材料与有机溶剂之间的界面性能。接着,按照0.3%(质量分数)的比例将碳纳米管、石墨烯以及碳纳米管/石墨烯杂化材料分别分散在环氧树脂中,通过DSC测试,分析杂化材料对环氧树脂固化行为的影响。结果表明:碳纳米管/石墨烯杂化材料在乙醇溶液中分散最稳定,同时杂化材料这种良好的分散性使其与树脂基体结合更为紧密,在树脂的固化过程中起到较好的促进作用。
The in situ polymerization was used to prepare carbon nanotube / graphene hybrid materials, and the three-dimensional structure of the hybrid materials was characterized by transmission electron microscopy. The interfacial properties between carbon nanomaterials and organic solvents were investigated by the dispersibility experiments of carbon nanomaterials in ethanol solution. Next, CNTs, graphene and carbon nanotube / graphene hybrid materials were respectively dispersed in epoxy resin in the proportion of 0.3% (mass fraction), and the curing behavior of the epoxy resin was analyzed by DSC Impact. The results show that the dispersion of CNTs / graphene hybrid materials in ethanol solution is the most stable, and the good dispersibility of hybrid materials makes them bond more tightly with the resin matrix and play a better role in the resin curing process The promotion effect.
