Thermal properties and reliabilities of myristic acid–paraffin wax binary eutectic mixture as a phase change material for solar energy storage

and 137.86 °C, respectively. Besides, analysis of the chemical and crystal structures of MA, PW and MA-PW revealed no chemical reaction between MA and PW to produce a new molecular structure and no change in the crystal structure. Finally, MA-PW binary eutectic PCM still has good thermal properties and chemical stability after 500 cold-hot cycles.
