Abstract Graphene materials (GMs) are deeply studied as nanoreinforcements of polymer matrices, especially for epoxy matrices. Here, we analyze the effect of GMs on the transport properties of a poly(bisphenol A-co-epichlorohydrin) resin. In particular, we focus on the effect of the morphology, chemical composition and structure of different GMs obtained by varying the reduction temperature of the thermal/exfoliation treatment of graphite oxide synthesized by a modified Hummers method. The dispersion degree of the GMs was studied by microscopy techniques, showing a strong dependence on the specific surface area and chemical composition of the graphene material. The transport properties imposed different requirements on GMs. The thermal conductivity benefited from a high aromatic restoration. Meanwhile, the electrical conductivity required the right balance of filler/matrix interaction and aromatic restoration.

石墨烯材料的主要结构特征控制环氧树脂基复合材料的传输性能

摘要 石墨烯材料 (GMs) 作为聚合物基质的纳米增强材料被深入研究,特别是对于环氧树脂基质。在这里,我们分析了 GM 对聚(双酚 A-co-环氧氯丙烷)树脂传输性能的影响。特别是,我们重点研究了通过改变通过改进 Hummers 方法合成的氧化石墨的热/剥离处理的还原温度获得的不同 GM 的形貌、化学成分和结构的影响。通过显微镜技术研究了 GMs 的分散程度,显示出对石墨烯材料的比表面积和化学成分的强烈依赖性。运输特性对 GM 提出了不同的要求。热导率得益于高芳烃恢复。同时,
