Thermal performance of a high conductive shape-stabilized thermal storage material

A composite based on paraffin, styrene–butadiene–styrene (SBS) triblock copolymer and exfoliated graphite (EG) is prepared. In this composite, paraffin undergoes solid–liquid phase change in the SBS network, and there is no leakage of it even in the state of melting. The composite exhibits high thermal conductivity and nearly 80% of the latent heat of fusion per unit mass of the paraffin.
