Novel temperature-control coating
Organic phase change material (PCM) is considered to be promising for building energy efficiency, as it can be directly incorporated into matrix resin to impart thermal storage capacity after being encapsulated in a shell to form phase change material microcapsules (EPCM). However, existing studies have shown that the encapsulation of organic shell materials negatively affects the inherent thermal storage efficiency of PCM and increases its fire hazard.
Practical application of building temperature-control coatings
Towards efficient utilisation of the thermal storage efficiency of organic PCM and reduction of its fire hazard when applied to building insulation coatings, researchers have decorated halloysite nanotube (HNT) with P, N component (p-HNT) and embedded it into EPCM (p-h-EPCM), which integrated the high thermal conductivity and flame retardancy of p-HNT and developed a high-performance EPCM for thermal regulation coatings. Considering the favorable flame retardant effect and energy-efficient thermal regulation performance, the obtained p-h-EPCM has a broad prospect in the practical application of building temperature-control coatings.
