The microencapsulation, thermal enhancement, and applications of medium and high?melting temperature phase change materials: A review

Microencapsulated phase change materials (MEPCMs) have made tremendous advancements in recent years, owing to their increased demand for a variety of energy storage applications. In this paper, current microencapsulation techniques, enhancement, and use medium- high-melting (PCMs) are reviewed, as well potential benefits limitations. The most frequently employed PCMs high-temperature applications were recognized salt-based, metallic, inorganic compound, eutectic. Meanwhile, polymethyl methacrylate (PMMA), polystyrene-butylacrylate (PSBA), polyethyl-2-cyanoacrylate (PECA), polyurethane widely used polymer shell encapsulating point via chemical method, whereas silica was synthesized various techniques. Hydrolysis followed by heat-oxidation treatment has been extensively studied since 2015 encapsulate either metal or alloy within Al2O3 shells. Different techniques developed generate void between core material accommodate volume expansion during transition. Numerous approaches, including the incorporation particles, carbon, ceramic, found ways enhance thermal performance PCMs. Multiple arrangements also established be an effective way enhancing overall efficiency medium-high melting PCM systems. Finally, paper highlights temperature solar power generation, cooking, industrial waste heat recovering
