Method of forming phase change material

A method to form a phase change material (PCM). The method includes preparing a polymer solution by mixing an amount of a polymer in a solvent and mixing the polymer solution with an UiO-66 metal-organic framework (MOF) to form a composite. The polymer is a polyethylene glycol (PEG). The method further includes subjecting the composite to ultrasonic agitation and evaporating the solvent from the composite to form the PCM. After the evaporation of the solvent, particles of the PCM exhibit rounded octahedral structures.
