Graphene size-dependent modulation of graphene frameworks contributing to the superior thermal conductivity of epoxy composites

Abstract

Graphene frameworks composed of quasi-isotropic and interconnected graphene were constructed <italic>via</italic> the filtration of graphene sheets with a small lateral size, endowing an epoxy composite (5.5 wt% graphene addition) with in- and through-plane thermal conductivities ∼55 and 29 times higher than those of neat epoxy, respectively.
