Al/Gf composite foams with SiC-engineered interfaces for the next generation of active heat dissipation materials

Interfacial engineering has been investigated as a method of increasing thermal conductivity in variety aluminium/graphite composites but remains unexplored the few graphite-containing aluminium foams developed to date. In this study, replication was used fabricate composite by infiltrating with liquid packed preforms containing SiC-coated oriented graphite flakes and NaCl particles, latter acting templating agent. The effects interfacial modification caused SiC presence were alongside those flake particle sizes. Materials benefit from low pressure drops when large particles are used. Furthermore, coated provide conductivities up 232 Wm−1K−1, improved mechanical properties power dissipation capacities 2-fold 6-fold higher than unmodified interfaces standard foams, respectively, making them ideal candidates for active heat sinks next-generation electronic devices.
