The aim of this study is to investigate the thermal properties of microencapsulated phase change material (μPCM) / multiwall carbon nanotube (MWCNT) composites. Several disc samples with 30mm diameter x 5mm width of μPCM/MWCNT composites were prepared with different mass fractions of MWCNT of 2, 4, 7 and 10 wt% using a compaction method. The thermal conductivity test was performed according to ASTM standard, while the latent heat property was calculated based on the theoretical equations. It was found that the thermal conductivity increase with mass fraction of MWCNT. However, the latent heat decreases with mass fraction of MWCNT. From these results, the optimized mass fraction of MWCNT approximately 5%, could be selected due it stable-form in thermal conductivity and latent heat capacity for electric vehicles (EVs) application. Furthermore, the reducing in melting time with increasing of MWCNT is accordance with the improvement of thermal conductivity.
