Abstract:
The thermal conductivity of zinc oxide-polymethyl methacrylate (PMMA) composites has been measured. Using theoretical models, the thermal resistance of ZnO-NW/PMMA interfaces (NW is the nanowire) and the critical particle radius above which the composite thermal conductivity can be increased have been estimated. Based on these measurements, the dependence of the thermal conductivity of zinc oxide nanowires on their diameter has been determined.
