Organic phase change materials (PCMs) are extensively used across various applications but limited by their low thermal conductivity. Enhancing PCMs with thermally conductive nanoparticles presents a promising approach to improve properties. This study explores the thermophysical characteristics of innovative nanocomposite incorporating boron nitride (BN) and zinc oxide (ZnO) nanoparticles, composites synthesized constant nanoparticle concentration 1.0 wt%. Detailed analyses reveal that BN ZnO uniformly dispersed without altering paraffin’s chemical structure. The hybrid HnCPCM 3, containing 0.5% BN, achieves an optimal latent heat fusion 204.24 kJ/kg highest conductivity 0.437 W/m K compared pure paraffin. Additionally, HnCPCMs show no separation, improved stability. These findings highlight significant potential nanocomposites for advancing energy storage management systems.
