Energy is a conserved quantity. The world demands increased energy supply in the future as a means to support life, in specific eco-friendly electricity. In this study, paraffin wax is doped using CNT and CNT/MgO composite at different composition namely 1, 2 and 3%. Similarly, the composition of CNT with MgO is varied in 50 and 75%. Various tests were performed such as thermal conductivity, zeta potential and electrical conductivity were conducted. Results showed that the thermal conductivity of the PCM with 3% CNT concentration is higher about 60% whereas, using CNT and MgO in the composition of 75/25 the thermal conductivity is enhanced to about 75%. On using MgO and 50% CNT–50% MgO, the thermal conductivity reduced. The average zeta potential of the material containing 50%, 75%, and 100% CNT is 0.298, −0.862, and −0.111 mV, respectively. Because of molecular interaction, the impact of electrical conductivity is lower in 100 percent CNT when compared to the hybrid mixture of both nanoparticles. When contrast to the hybrid mixes, the CNT has a low molecular interaction.
