Preparation of microcapsules containing HD as a phase change material: an investigation into Core to shell ratio and surfactant amount

Phase change materials (PCMs) are used as renewable energy resources and can absorb and release large amount of heat in response to changes in environmental temperatures, repeatedly.Encapsulation enhances their efficiency and prevents leakage when phase change occurs [1].In present study, microencapsulated phase change materials (m-PCMs) have been prepared through in-situ condensation polymerization. n-Hexadecane (HD) as PCM and melamineformaldehyde(MF) were used in the composition of the core and shell respectively
