Microencapsulated paraffin with SiO2 and Cu-BTC composite shell as shape-stabilized thermal energy storage materials
https://orcid.org/0000-0001-7924-0573
Abstract Microencapsulated phase change materials (MEPCMs) containing paraffin were fabricated by chemical precipitation and complexation using SiO2 and Cu-BTC MOF as composite shell materials. Physicochemical properties of the synthesized materials were characterized by various techniques. The composite materials were evaluated for benzene vapor sorption isotherm, NH3 adsorption isotherm, and formaldehyde adsorption. The melting temperature, latent heat and encapsulation ratio of MEPCM were determined to be 22.7 °C, 84.5 J/g and 44.5%, respectively. After 100 melting-freezing cycles, the heat storage and heat release capacities of MEPCM were reduced by less than 2.0% and 1.7%, respectively. Besides, the as-prepared MEPCM can be usedas a microcapsule material for indoor building purification to remove indoor pollutants. Compared with the reference, the building with the MEPCM/gypsum board has a noticeable reduction of periodic fluctuations in temperature and humidity, which are conducive to storing time-dependent and intermittent solar energy and improvingthe quality of the living environment.
