Graphene-Based Phase Change Composite Nano-Materials for Thermal Storage Applications

We report results concerning the functionalization of graphene-based nanoplatelets for improving thermal energy storage capacity commonly used phase change materials (PCMs). The goal this study was to enhance low conductivity PCMs, while preserving their specific and latent heats. focused on wax-based we tested several types graphene nanoparticles (GNPs) at a set different concentrations. Both size shape GNPs were found be important factors affecting PCM’s properties. These evaluated using differential scanning calorimetry measurements modified enthalpy-based water bath method. that small addition (1% weight) with high aspect ratio is sufficient double widely PCMs. Our suggest simple efficient procedure properties PCMs in applications.
