Abstract: With paraffin as phase change material(PCM) and expanded graphite with network structure as matrix,a composite phase change material was prepared through physical adsorption,and was compressed to a shape-stabilized cylinder block by the compacting tool set.The prepared composite phase change material was characterized with differential scanning calorimeter(DSC),scanning electron microscope(SEM),polarizing optical microscope(POM)and Hot Disk thermal analyzer.In addition,an experimental system was set up to measure its thermal cycling performance.The results showed that melting temperature of the shape-stabilized phase change material with 80% mass fraction of paraffin was 27.27℃ and its phase transition enthalpy was 156.6 kJ·kg-1.The prepared shape-stabilized phase change material had many advantages over pure paraffin,such as a form-stable phase change process,higher thermal conductivity and heat storage capacity,excellent thermal stability and a longer service life.

Key words: paraffin, expanded graphite, physical adsorption, shape-stabilized phase change material
