Abstract
ABSTRACT Solid‐solid phase change materials (SSPCMs) hold great promise for thermal management, yet their development has long been hindered by the “impossible triangle”: simultaneously achieving high energy density, robust mechanical properties, and full recyclability. This study presents a strategy to address this trilemma by constructing a reversible physically crosslinked network based on stereocomplex poly(lactic acid) (sc‐PLA) crystallites. In this system, polyethylene glycol (PEG) segments provide thermal energy storage, while sc‐PLA crystallites stabilized by dense hydrogen bonding serve as physical crosslinkers to impart mechanical integrity. The resulting material exhibits ultrahigh stretchability…
