Solid-solid phase change materials (SSPCMs) are considered among the most promising candidates for thermal energy storage and management. However, application of SSPCMs is consistently hindered by canonical trade-off between high TES capacity mechanical robustness. In addition, they suffer from poor recyclability due to chemical cross-linking. Herein, a straightforward but effective strategy fabricating supramolecular with latent heat strength proposed. The polymer employs multiple H-bonding interactions as robust physical cross-links. This enables SSPCM enthalpy transition (142.5 J g

Abstract Supramolecular polymer networks (SPNs), crosslinked by noncovalent bonds, have emerged as reorganizable and recyclable polymeric materials with unique functionality. However, poor stability is an imperative challenge faced SPNs, because SPNs are susceptible to heat, water, and/or solvents due the dynamic reversible nature of bonds. Herein, design a cooperative network (NCoN) simultaneously stabilize reinforce reported, resulting in ultrastable, superrobust, SPN. The NCoN constructed multiplying H‐bonding sites tuning conformation/geometry segment optimize multivalence cooperativity H‐bonds. rationally designed high conformational compliance favors formation tightly packed H‐bond arrays comprising higher‐density stronger Consequently, H‐bonded crosslinks display covalent crosslinking effect but retain on‐demand dynamics reversibility. resultant ultrastable SPN not only displays remarkable resistance heat up 120 °C, water soaking, broad spectrum solvents, also possesses superhigh true stress at break (1.1 GPa) ultrahigh toughness (406 MJ m −3 ). Despite covalent‐network‐like stability, through activating its reversibility high‐polarity solvent heated threshold temperature.

Despite the recent rapid advancements in room-temperature self-healing waterborne polyurethanes, imparting fast ability while concurrently maintaining robust mechanical performance of polyurethanes remains a formidable challenge. Herein, we propose molecular structure design strategy for developing visible light-responsive, self-healing, and antibacterial polyurethane (DMZWPU) containing triple dynamic bonds diselenide bonds, multiple hydrogen Zn(II)–carboxylate coordination bonds. This innovative approach effectively balances tensile stress, fracture toughness, material.
