Thermal performance of modified melamine foam/graphene/paraffin wax composite phase change materials for solar-thermal energy conversion and storage

Wei Cui et al.

Summary: This study addresses the issues of leakage, poor thermal conductivity, and poor light absorption in phase change materials (PCMs) by combining modified melamine foam (MF) and graphene nanoparticles (GNP). The composite PCMs fabricated with modified MF, paraffin wax (PW), and GNP exhibit good leakproof ability, high thermal conductivity, and excellent solar-thermal energy conversion capability. Furthermore, a thermoelectric conversion system driven by solar energy was developed to demonstrate the potential of these composite PCMs for cleaner energy production.
