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...
Chitosan, as a low-price and eco-friendly raw material, was used to synthesize a graphene-based carbon aerogel (CA). Afterwards, 1-hexadecanol was infiltrated into CA to prepare a form-stable phase change material (PCM) for thermal energy storage. The morphologies and thermal properties of samples were analyzed. Even at 70°C, the form-stable PCM still retains form stability without any leakage. TGA...
Al2O3 coated graphene foam (GF@Al2O3) composites are proposed by depositing insulating Al2O3 particles on the graphene with a simple method. The content of Al2O3 on graphene could be gradually adjusted by changing Al(OH)3 radio in solution. Al2O3 coated graphene foam composites are used as effective three dimension (3D) interconnected framework of paraffin phase change materials to increase thermal...
