| Annotation | The thermal conductivity of the composite materials based on the zinc oxide powders with different average particle sizes (micrometer, submicrometer and nanometer) dispersed in the polymethylsiloxane (silicone oil) was measured using the radial heat flow method. The thermal conductivity of the composite material based on the commercial ZnO micropowder with an average particle size of 50 m was found to be 0.8 W/(m∙K). The thermal conductivity of the composite material on the basis of ZnO nanopowder with an average particle size of approximately 3 nm synthesized using the wet chemistry methods was found to be 2.5 W/(m∙K). The discovered enhancement of the above mentioned parameter is considered as manifestation of the quantum size effects in heat transfer. |
