Thermal Conductivity Enhancement of Novel Phase Change Materials with Graphene Nanoplatelets: A Comparative Study

Gunasekaran Yogeswaran and Ponrajan Vikram

Abstract

The main goal of this research is to enhance the thermal conductivity of a commercial phase change material (PCM) (CR+28) by incorporating graphene nanoparticles (GNP). The PCM was standardized to have a latent heat of 180 kJ/kg, a specific heat of 2.1 – 1.5 kJ/kg.K, and thermal conductivity of 0.5 – 1.1 W/m.K. 10 g of GNP was added to the PCM for group 1, while the standard PCM was used for group 2. There were 20 samples in each group, and the sample size calculation was done using a G-power of 80%, ɑ = 0.05 per set, resulting in a total sample size of 40. The 10 g GNP in PCM showed high thermal conductivity, which was 5.35% more than the standard PCM without GNP. Statistical analysis showed a significant difference in the mean-variance of thermal conductivity between group 1 and group 2, with a p-value of 0.001 (p < 0.05). Based on the findings of this study, it can be concluded that adding 10g of GNP to the PCM significantly improves its thermal conductivity.
