Abstract

Graphene nanosheets (GNS) paper is widely regarded as a promising candidate for heat dissipation due to its outstanding thermal conductivity. However, the accompanied high electrical conductivity makes it unfavorable for thermal management of high power electronics since it runs a high risk of short circuits. To eliminate the risk from the high electrical conductivity and simultaneously maintain the excellent thermal performance, boron nitride nanosheets (BNNS) with high thermal conductivity but electrical insulation were introduced into GNS paper. The hybrid paper has much lower electrical conductivity but similar thermal performance compared with pristine GNS paper, and also exhibits better thermal stability.
