Abstract

Highlights: Melamine formaldehyde (MF) based capric acid(CA) microcapsules were prepared. Colemanite-MF composites based CA microcapsules were prepared. Influence of the colemanite amount on thermal properties of microcapsules reported. Less environmental footprint and less chemical content were produced. The microcapsules store excess heat and can reduce the heating and cooling load of buildings. Abstract: In recent years, polymer/mineral composites with desired properties have been produced by adding natural minerals to polymers due to being a natural resource, their low costs and ease of use. In this study, capric acid (decanoic acid, CA) microencapsulated with melamine formaldehyde (MF) and colemanite doped MF composites (cMF) as thermal energy storage materials. Thermal, chemical, and morphological properties of cMF based PCM microcapsules and microcomposites was determined. The analysis results indicate that the addition of suitable amounts of colemanite has a positive impact on both the thermal stability and the capacity for thermal energy storage of the prepared microcapsules. The produced cMF based CA microcapsules melts at ∼28 °C with corresponding latent heat of ∼89 J/g. It can be stated that the usage of cMF based CA microcapsules and microcomposites in buildings can reduce the increasing energy load which results in the contribution to the formation of a clean environment by preventing the increase of greenhouse gases because of less use of fossil fuels.
