BN-SiO₂ 3D-Framework Epoxy Composite

215% TC boost at 5 wt% filler

A polyurethane sponge template creates a 3D thermally conductive network of BN nanosheets and silica nanoparticles, drastically reducing interfacial thermal resistance at very low filler loading for electrically insulating epoxy composites.
