Abstract: The use of phase change materials to store thermal energy is an effective way to improve the efficiency of traditional energy utilization and develop various new energy sources. Solid-liquid phase change energy storage materials have the advantages of low cost, wide range of solidification point adjustment and large enthalpy of phase change, which make them become one of the most widely used phase change materials among phase change materials. However, the low thermal conductivity and leakage problems occur during the use of phase change materials, which greatly limit the practical application of phase change materials. To solve the above problems, oxidized carbon nanotubes (O-MWCNTs) loaded with silver nanoparticles were introduced into a microcrystalline cellulose (MCC) matrix to prepare a three-dimensional porous skeleton of microcrystalline cellulose/multi-walled carbon nanotubes loaded with silver (MCC/Ag-MWCNTs) in this work, and the MCC/Ag-MWCNTs/PA(Ag-PMCT) composite phase change material was obtained by adsorbing palmitic acid (PA) on the MCC/Ag-MWCNTs composite framework, abundant silver nanoparticles on O-MWCNTs form micro ‘bridges' on carbon nanotubes, thus constructing a complete thermal conduction path, which further improved the thermal storage performance of the composite phase change material. At the same time, the MCC/Ag-MWCNTs composite 3D skeleton exhibits good encapsulation effect and shape stability. The Ag-PMCT composite phase change materials prepared in this paper have potential applications in the field of energy saving in buildings and thermal management of electronic devices, and provide a new idea for the enhancement of thermal conductivity of phase change materials by carbon based materials and metal particles together.
