“…The thermal conductivity of the composite is improved more significantly when the filler size is in the micrometer range; however, micron-level metal powders are mostly only blended with thermoplastic resins with a higher viscosity due to their high density. For example, silver, copper, , nickel, and aluminum (Al) particles can be blended with polyvinyl alcohol, polymethylmethacrylate, polystyrene, polyimide, etc. to achieve uniform dispersion.…”

Metal fillers are not suitable for direct mixing and casting with thermosetting resins to prepare thermally conductive and insulating materials due to their high density and electrical conductivity. Here, we obtain a filter cake by mixing sepiolite fiber, tin powder, and h-BN through vacuum filtration. Low melting point tin particles are melted and allowed to infiltrate to fill the void defects around them after the filter cake is heat-treated, and the added h-BN will coat the tin particles to prevent them from coming into contact with each other to conduct electricity but does not hinder heat conduction. The test results show that when the tin powder content is about 47.2 wt %, the thermal conductivity can reach 3.37 W/m•K and the volume resistance is still greater than 10 9 Ω•m. This method provides an idea for the preparation of high thermal conductivity metal-thermosetting resin composite materials.

“…22 Among metals, Ag is an effective coating material because of its high thermal conductivity and oxidation resistance. 23 Ha et al 24 prepared polyvinyl alcohol composite films (Ag-GNPs-PVA) through a nano-silver modified graphite nanosheet by using the solution delay flow method. Compared with pure graphite nanosheet polyvinyl alcohol composite films (7.61 W/(mK)), the thermal conductivity of 10 wt.% Ag-GNPs composite films was 8.45 W/(mK).…”

Ag@BN/phthalonitrile resin composites were prepared using highly thermally conductive BN modified by Ag plating. The effects of different contents of Ag@BN particles on the dynamic mechanical properties, thermal stability, and thermal conductivity of composites were examined. The results of Fourier-transform infrared spectroscopy, X-ray powder diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy analyses showed that Ag was successfully deposited on the surface of BN. The prepared Ag@BN was subjected to KH550 grafting treatment. With the increase in the content of Ag@BN/KH550, the storage modulus, thermal stability, and thermal conductivity of the composite increased. The storage modulus, decomposition temperature, and thermal conductivity of the Ag@BN/phthalonitrile composite with 20 wt.% Ag@BN/KH550 were 5.0 GPa, 539°C, and 0.80 W/(mK), respectively, which are 1.35, 1.18, and 3.33 times higher than those of pure resin, respectively. The compatibility and dispersibility of BN modified by Ag plating in phthalonitrile resin were effectively enhanced, thereby providing a potential candidate to be used at high-temperature devices with high thermal conductivity.
