MOF and GNS work synergistically for low-k materials with higher thermal conductivity

In this work, the low dielectric constant composites with higher thermal conductivity are prepared, combining ZIF-8 insulation and graphite nanosheets (GNS) thermal conductivity via designing suitable configuration and synergistically reacting in epoxy resin matrix. It demonstrated that ZIF-8@GNS/EP (ZGNS/EP) composites have decreased by 26.4% in low dielectric constant and increased by 300.7% in thermal conductivity compared with neat EP. The dielectric loss of composites is always less than 0.033(10 2 –10 7 Hz). Simultaneously, the tensile strength of the 0.5 wt% ZGNS/EP composite is increased by 71.1% than before. Overall, this work presents new ideal to prepare low dielectric constant materials, which also possess low loss and excellent thermal conductivity.
