| Abstract: | In this paper,based on paraffin and thermoplastic elastomer poly(styrene-butadiene-styrene) shape-stabilized phase change materials(PCMs) are prepared.They exhibit same phase transition characteristics as paraffin and up to 80% of the latent heat of paraffin.Thermal conductivity of the shape-stabilized PCMs is increased significantly by the introduction of expanded graphite(EG).The time for complete solidification of the composite PCM is 61% that of paraffin. |
