Metal nanowire-polymer nanocomposite as thermal interface material

Thermal properties of silver nanowire-silicone (AgNW-silicone) composites at different weight percentage of AgNW in the polymer were studied. The thermal conductivity of these composites was measured using the heat stack method according to D5470 standard. The silver nanowires were synthesized using a polyol process. The nanocomposites were prepared by solution mix processing. The effective thermal conductivity of the AgNW-silicone nanocomposite increased with the enhancement of AgNW concentration and the thermal conductivity were found higher than that of traditional silicone composites using micron sized silver flakes as fillers with the same concentration.
