Thermal percolation and electrical insulation in composite materials with partially metallic coated fillers

We propose a type of thermal interface materials incorporating insulating nanowires with partially metallic coating in polymer matrix. Large conductivity can be obtained due to percolation while the electrical insulation is maintained by controlling CM?<?ce and ?>?cth, where ? volume fraction fillers, CM fraction, ?ce ?cth are thresholds, respectively. The such composite further regulated configuration. In this regard, we concept “thermal-percolation electrical-insulation,” providing guide design efficient hybrid materials.
