High temperature phase change materials based on inorganic salts and carbon Nanomaterials - (PPT)

摘要

High temperature phase change material is useful for solar thermal power generation, industrial process heat and waste heat recovery. In this paper, inorganic salts and carbon nanomaterials, such as expanded graphite (EG) carbon nanotube and graphene, are used to prepare high temperature phase change material. Inorganic salt/EG/carbon nanotube/Graphene composites as phase change materials are prepared by aqueous solution method. The influence of EG, carbon nanotube and graphene on the thermal conductivity of composites is studied by MDSC. Results show that expanded graphite, carbon nanotube and graphene can significantly increase the thermal conductivity of high temperature phase change materials.
