The waste plastics-derived waxes were characterized and studied for a potential new application: phase change materials (PCMs) for thermal energy storage (TES). Gas chromatography–mass spectrometry analysis showed that paraffin makes up most of the composition of HDPE and LDPE waxes, whereas PP wax contains a mixture

In recent years, phase change materials (PCMs) have increasingly received attention in different thermal energy storage and management fields. In the
For this purpose, paraffin wax has been chosen as the ideal phase change material due to its exceptional attributes that facilitate the development of a composite energy storage material. The specific properties of paraffin wax are such as the latent heat of fusion for the substance is recorded at 226 kJ/kg.
Paraffins are useful as phase change materials (PCMs) for thermal energy storage (TES) via their melting transition, T mpt.Paraffins with T mpt between 30 and 60 C have particular utility in improving the efficiency of solar energy capture systems and for thermal buffering of electronics and batteries.
Or with solar collectors [6], [7], [8], this technology is beneficial because it prevents the loss of heat and energy in pipes or duct networks, and also in terms of cost as storage tanks and
The development of phase change materials (PCMs) is hampered by issues like leakage, poor thermal conductivity, and poor light absorption this study, we innovatively combined modified melamine foam (MF) and graphene nanoparticle (GNP) to address these defects of PCMs in the solar-thermal energy system.
Values of energy supply and demand vary within the same timeframe and are not equal. Consequently, to minimise the amount of energy wasted, there is a need to use various types of energy storing systems. Recently, one can observe a trend in which phase
