Advances in Organic Porous Polymeric‐Supported Photothermal Phase Change Materials

ABSTRACT The urgent demand for renewable energy solutions, propelled by the global energy crisis and environmental concerns, has spurred the creation of innovative materials for solar thermal storage. Photothermal phase change materials (PTPCMs) represent a novel type of composite phase change material (PCM) aimed at improving thermal storage efficiency by incorporating photothermal materials into traditional PCMs and encapsulating them within porous structures. Various porous encapsulation materials have been studied, including porous carbon, expanded graphite, and ceramics, but issues like brittleness hinder their practical use. To overcome these limitations, flexible PTPCMs using organic porous…
