Is paraffin wax a good energy storage material?

Energy storage (ES) is one of the major challenges today, particularly with the growing demand for renewable energy sources. Due to high latent heat (LH) capacity, phase change materials (PCMs) such as paraffin wax (PW) have been widely used for thermal energy storage (TES); the low thermal conductivity (TC) of PW limits its practical usage.

Why is paraffin wax more energy absorbed at high temperatures?

Enhanced molecular vibrations and lattice expansion at high temperatures allow for increased energy absorption. Paraffin wax has a higher degree of molecular freedom so when temperature rises heat capacity increases, so it retains more thermal energy.

Why does paraffin wax have a higher heat capacity than MXene?

Paraffin wax has a higher degree of molecular freedom so when temperature rises heat capacity increases, so it retains more thermal energy. The large heat capacity is further affected by the incorporation of MXene, with maximum enhancement at 0.03 M concentration.
