Selection of waste thermoplastics for shape stabilized phase change materials using multicriteria techniques

Abstract

A variety of polymer matrices, based on thermoplastic resins are used to produce shape stabilized phase change material (SSPCM) with a large range of chemical and mechanical properties. In order to reduce global environmental problems and conserve natural resources, instead of raw polymers, waste thermoplastics can be utilized as encapsulation material to produce SSPCM. Low-density polyethylene (LDPE), high-density polyethylene (HDPE), polystyrene (PS), and poly-

A critical review of polymer support‐based shape‐stabilized phase change materials for thermal energy storage applications

“…LDPE was identified as the optimal choice for SSPCM manufacturing, considering its thermal, mechanical, and waste characteristics. 36 Gencel et al developed SSPCMs by integrating PCMs with geopolymer concrete (GPC), resulting in materials with improved thermal properties. 37 The developed material shows promise for advanced TES applications in buildings, indicating a focus on cost-effectiveness.…”

“…Some studies have investigated employing waste thermoplastics as encapsulation materials, potentially lessening their ecological footprint and aiding in reducing waste and conserving resources. 36 By incorporating waste stone fragments and employing low-toxic, low-flammability polymers in SSPCM production, there is an advancement towards aligning with the principles of a circular economy and diminishing the ecological footprint of manufacturing processes. 25 Therefore, encapsulating PCMs within waste plastics offers a dual benefit of mitigating plastic waste pollution while enhancing the energy storage capabilities of the materials.…”
