Aluminum Coated Spherical Particles Filled Paraffin Wax as A Phase-change Thermal Interface Materials

In this paper, we reported thermally conductive insulating phase change materials filled with Al2O3-coated Al powder (PCMs/Al@Al2O3) and investigated the effect of composite PCMs on the thermal conductive performance. Result revealed that the content of Al@Al2O3 combines the advantages of both aluminum and alumina. The PCMs/Al@Al2O3 has a thermal conductivity value of 1.6743 w/mk, which is three times as much as the PCMs/Al2O3, and it shows a better ability to prevent leakage. © 2017 IEEE.
