Abstract
Nowadays nano phase change materials (PCMs) are commonly preferred by engineers for researches and to use them for thermal storage materials. This is because these materials store and release a large amount of latent heat during the process of melting and freezing which means changing from one phase to another. Engineers can use this property of PCMs in many ways such as thermal energy storage where the heat or coolness can be stored from one process and can be used later or at different locations. Thermal conductive substance such as nanoparticles is added to the former to increase the thermal conductivity of PCM and these materials are known as nano-enhanced PCM. To study the properties of fabricated composites, some characterization tests have done including Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), differential scanning calorimetry (DSC) and thermal and electrical conductivity tests. In this paper we will discuss the ideal characteristics of nano-enhanced PCM, thermo-physical properties, applications along with the challenges and direction of this new material and hoped this review will explore and provide some applications and the fundamental properties of composite PCM with CNT/graphene. By this experiment, thermal conductivity of nano-enhanced PCM gets increased. This composite PCM shows the huge potential in thermal energy storage system.
