Recent Advances in Organic/Composite Phase Change Materials (PCM) for Energy Storage

This chapter discusses current developments in the research and advancement of organic and composite phase change materials (PCM) for energy storage applications. PCM is a group of substances that can store and release thermal energy throughout the melting and solidification processes. It makes them excellent for thermal management, building insulation, and renewable energy storage, including a high latent heat storage capacity. The interfacial polymerization method, the process of spray drying, the technique based on the adsorption of absorbent materials, the sol-gel method, process including melting, impregnating, and blending, the electrospinning method, and the ultrasonic method are some of the typical preparation methods that have been introduced in recent developments in the synthesis of new organic and composite PCM using advanced fabrication techniques, such as electrospinning and 3D printing, and novel materials like graphene and carbon nanotubes. Furthermore, an analysis will be conducted to explore the potential applications of these innovative materials and technologies in the realm of energy-efficient constructions, solar thermal energy storage, heating and cooling systems, food production, the textile industry, recovery of industrial waste heat, and the integration of high-capacity battery systems. A comprehensive summary of the current research and development status of organic and composite PCM emphasizes the potential for these materials to play a crucial role in transitioning to a low-carbon, sustainable energy future.
