Characterization of Enhanced Biobased Phase Change Material with Graphene Nanoplatelets – Early Results

Costa Pereira, Carolina

Abstract

Energy consumption is expected to continue rising, and in conjunction with greater environmental concern, it has boosted the development of renewable and sustainable energy sources, including storage media materials for thermal energy storage (TES) systems. Biobased Phase Change Materials (PCMs) are materials derived from renewable and environmentally friendly resources, such as palm oil, and are a great solution as they have similar properties to paraffin-based PCMs. Therefore, in view of designing a nano-enhanced PCMs (NePCMs) based on a commercial plant-based PCM, CrodaTherm60, was selected due to its high latent heat capacity as well as its medium melting point, 60 °C, making it suitable for solar domestic hot water systems (SDWHs). Whilst the selected PCM has desirable properties, it still possesses the most common limitations, such as its low thermal conductivity; thus, NePCMs were prepared and characterized using carbon-based nanoparticles, and graphene nanoplatelets (GNPs).
