Phase change materials (PCM) have become researcher interest in the area of thermal energy storage (TES) due to their high storage capacity, simple structure, low cost and so on. However, its application in TES is limited due to leakage issues. In this study, a leakage-proof composite PCM has been successfully prepared, in which paraffin is used as PCM and styrene-b-(ethylene-ran-butylene)-b-styrene (SEBS) as supporting material. Furthermore, different mass fraction, i.e., 10, 15 and 20wt% of SEBS, is incorporated in paraffin to investigate the performance of the composites against the leakage issue of paraffin. Results revealed that when the mass fraction of SEBS reached 20wt%, negligible leakage of paraffin has been observed. Moreover, the thermal stability of composite PCM has been determined by thermogravimetric analysis. TGA and DSC results suggested that the degradation of composites is negligible below 200oC with an excellent storage capacity of about 167.91 J/g. Finally, the heat transfer performance has been observed experimentally.
