“…The TIMs yielded a high stretchability (∼400%) but still had a moderate increase of thermal conductivity (0.81 W m –1 K –1 ), 5.4-fold higher than that of neat nature rubber (0.15 W m –1 K –1 ). The mechanical performances of BN-PCPA-Si69/NR composites also improved significantly with the maximum tensile strength reaching up 17.0 MPa . It remains largely unexplored to engineer stretchable and thermally conductive TIMs.…”

“…Adding 4 wt% modified boron nitride can significantly improve the flame retardant performance and thermal conductivity of natural rubber. Yang et al 17 modified h-BN with polycatechol/polyamine (PCPA) and united it with bis-(γ-triethoxysilylpropyl)-tetrasulfide (Si69) to get BN-PCPA-Si69 and then applied it to natural rubber. The research indicated that the PCPA coating decreased the interface phonon dispersion between the substrate and the filler and effectively improved the thermal conductivity of natural rubber.…”

“…In general, metallic, , carbon materials, , and ceramic materials , are introduced into the polymers to improve λ of the polymeric composites. , Hexagonal boron nitride (BN) is incorporated in various polymers due to its high λ (∼30 W/mK in the through-plane direction and ∼600 W/mK in the in-plane direction), outstanding electrical insulation, and high-temperature antioxidation resistance. Due to the honeycomb atom layered structure that is similar to graphite, BN is usually called “white graphene” . However, owing to their high specific surface area, BN platelets usually agglomerate at high loadings, which induces more interfacial thermal barriers and decreases the λ of polymeric composites.…”
