Based on the fast growth of the deviceperformance, there has been an increasing demand for handling the issue ofthermal management in electronic equipments. Therefore, it is of great significanceto improve the thermal conductivity of the polymers, which are commonly used inelectronic components. Due to the high intrinsic thermal conductivity, grapheneexhibited great potential to be incorporated in the polymer matrix for thedevelopment of polymer composites with significant thermal conductivityenhancement. However, the difficulty of graphene dispersion and stronginterfacial phonon scattering restrict the heat dissipation performance ofgraphene/polymer composites. The creation of bioinspired graphene architecture with controlled three-dimensional structure in the polymer matrix represents a promising solution for the issue of the difficulty of graphene dispersion, and leads to remarkable improvement of heat transfer capacity of the composites.Our works provide a path to develop a variety of highly thermally conductive polymer composites for use in heat dissipation and other thermal applications.
