Shape-stabilized phase change material with highly thermal conductive matrix developed by one-step pyrolysis method

Abstract Metal microspheres doping porous carbon (MMPC), which was prepared using in-situ pyrolysis reduction strategy, could enhance the thermal conductivity of shape-stabilized phase change material (ss-PCM) prepared by MMPC as the matrix. However, in previous studies that were reported, the prepa...
