摘要

This study investigated different contents of an anhydride curing agent, an accelerant, and non-ionic surfactants on the electrical resistivity of cured graphene/epoxy composites. The anhydride curing agent was hexahydrophthalic anhydride (HHPA), the accelerant was 2-ethyl-4-methyl-1H-imidazole-1-propanenitrile (EMIP), and the non-ionic surfactants were Triton X surfactants with different numbers of polyethylene oxide (PEO) groups (m) that influence the electrical resistivity of cured graphene/epoxy composites. During the curing process, differential scanning calorimetry (DSC) was used to determine the effects of the extent of the crosslinking for different contents of the curing agent and how different enthalpy (H) on the electrical resistivity of the cured graphene/epoxy composites was then generated. The cured graphene/epoxy compositewhich consisted of a 1 : 0.85 weight ratio of epoxy resin and anhydride, a 0.5 wt % accelerant, and a 13 wt % graphene powderhad a low electrical resistivity of 11.68 cm and a thermal conductivity of 1.7 W/mK. In addition, the cured composites contained a 1.0 wt % polyethylene glycol p-isooctylphenyl ether (X-100) surfactant, which effectively decreased their electrical resistivity.
