The Effect on Heating Rate for Phase Change Materials Containing MWCNTs

Tun-Ping Teng and Chao-Chieh Yu

Abstract—This study experimentally investigates the influences of the additive concentrations of the MWCNTs and heating/cooling rate for the nanocomposite-enhanced phase change materials (NEPCMs). The variations of temperature and phase change heat of NEPCMs by DSC experiments are to evaluate the feasibility for heat storage. Experimental results demonstrate that adding MWCNTs reduced the melting onset temperature and increased the solidification onset temperature for paraffin. This phenomenon makes the phase change heat of NEPCMs applicable to a wider temperature range, and the highest decreased ratio of phase change heat with 3.0 wt.% of MWCNTs was only 2.0 % to compare with paraffin at 2.0 oC/min. of cooling rate in this study.

Index Terms—MWCNTs, NEPCMs, paraffin, phase changeheat
