Inefficient dissipation of heat limits the performance of electronic devices. Thermal interface materials (TIMs) can be used in electronic devices to dissipate heat more effectively and efficiently. Nanocomposites have been prepared using functionalized boron nitride nanosheets (BNNS). The incorporation of soft-ligand functionalized BNNS in a metal matrix was used to nanofabricate kinetically-trapped nanocomposites TIMs.
