제목 Graphene Fluoride Assembled Polyurethane Foam In Epoxy Composites to Achieve High Thermal Conductivity and Electrical Insulation
초록 Effective heat dissipation from electronic devices has become one of the most pressing issues. Herein, we developed the thermally conducting yet electrically insulating graphene fluoride (GF) based epoxy composites. A cyclic assembly deposition approach was used to coat GF on the cell walls of polyurethane foam (PUF), followed by the PUF@GF foam was compressed immersed in epoxy resin. Notably, with 8.04 vol% GF loading, the fabricated 3D GF epoxy composites had a thermal conductivity of 9.68 W/mK, corresponding to the thermal conductivity enhancement of 4994% in comparison to that of the neat epoxy. This approach demonstrates a cost-effective method for fabricating thermoconductive composites with electrical insulation that could be used in electronic applications for heat dissipation. The research was supported by a grant from the Academic Research Program of Korea National University of Transportation in 2022. Composites Part A 149 106585 (2021).
