Published: May 16, 2024

The adoption of phase change materials (PCMs) for thermal energy storage in low‐ and medium‐temperature settings is witnessing a notable surge. However, the lesser conductivity (TC) poses noteworthy challenge to PCM's heat transfer capabilities. One solutions augment TC incorporating nanoparticles PCM. Nevertheless, often clump together after several cycles due poor compatibility weak interfacial strength. Functionalization methods have been proposed address this issue, offering improved performance applications. Herein, graphene nanoplatelets (GNP) functionalized (FGNP) are dispersed into A70 PCM at mass fractions ranging from 0.1 1.0 wt% using two‐step method. Fourier transform infrared analysis confirms successful integration FGNP without altering its chemical characteristics. Adding increases by 140.88%, with just 3.02% decrease latent enthalpy. pure GNP (1.0 wt%) improves 48.83%. engineered nano‐PCMs exhibit robust stability even undergoing 1000 cycles, remaining unchanged up 414.64 °C.
