摘要

采用超声波法对氧化石墨烯(GO)、化学改性氧化石墨烯、两相萃取氧化石墨烯水溶液制备了石墨烯基环氧纳米复合材料。所有的样品都进行了后固化，热处理提供了氧化石墨烯在环氧网状基体中的原位热还原。样品的电导率已被测量，显示不同的行为取决于纳米填料和所采用的生产程序。含有0.5 wt%氧化石墨烯的样品的电导率值比纯环氧树脂高80倍。

Electrical conductivity of graphene-based epoxy nanodielectrics

Graphene-based epoxy nanocomposites have been produced by the ultrasonication of graphene oxide (GO), chemically modified GO and through two-phase extraction of GO water solution. All the samples have been post-cured and the thermal treatment provided a thermal in situ reduction of GO into the epoxy reticulated matrix. Electrical conductivity of the samples has been measured showing different behavior depending on both the nanofiller and the production procedure employed. Sample with 0.5 wt% of GO shows conductivity values 80 times higher than the neat epoxy.
