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

Phase-change materials (PCMs) have received considerable attention to take advantage of both pad-type and grease-type thermal interface (TIMs). However, the critical drawbacks leaking, non-recyclability, low conductivity (κ) hinder industrial applications PCM TIMs. Here, leakage-free healable TIMs with extraordinarily high κ total resistance (Rt ) are reported. The matrix material (OP) is synthesized by covalently functionalizing octadecanol polyethylene-co-methyl acrylate-co-glycidyl methacrylate polymer through nucleophilic epoxy ring opening reaction. OP changes from semicrystalline amorphous above phase-transition temperature, preventing leaking. hydrogen-bond-forming functional groups in enable nearly perfect healing efficiencies tensile strength (99.7%), (97.0%), Rt (97.4%). Elaborately designed thermally conductive fillers, silver flakes multiwalled carbon nanotubes decorated nanoparticles (nAgMWNTs), additionally introduced (OP-Ag-nAgMWNT). nAgMWNTs bridge silver-flake islands, resulting (43.4 W m-1 K-1 (30.5 mm2 K W-1 compared literature.

Abstract Solid–solid phase change materials (SSPCMs) with crosslinked polymer structures have received sustained interest due to their remarkable shape stability, enabling application independently without the need for encapsulation or supporting materials. However, crosslinking structure also compromises latent heat and poses challenges recyclability. Herein, a novel strategy harnessing internal‐catalyzed reversible anhydride‐alcohol reaction fabricate SSPCMs superior exceptional dual recyclability is presented. Easily accessible anhydride copolymers (e.g., propylene‐maleic alternating copolymers), provide abundant reactive sites within matrix; polyethylene glycol serves as both grafted component crosslinker. The resulting attain peak value of 156.8 J g −1 which surpasses all other reported recyclable SSPCMs. exhibit certain flexibility tunable tensile strength ranging from 6.6 11.0 MPa.

Abstract Phase change materials (PCMs) are promising thermal energy storage due to their high specific latent heat. Conventional PCMs typically exploit the solid–liquid (s–l) transition. However, leakage and leaching common issues for PCMs, which have be addressed before usage in practical applications. In contrast, solid–solid (s–s) would naturally overcome these inherent form stability homogeneity. this study, we report a new type of s–s PCM based on chemically linked polyethylene glycol (PEG, portion) with polylactic acid (PLA, support block co‐polymer. Solid‐solid heat up 56 J/g could achieved, melting points between 44 °C 55 °C. For comparison, PEG was physically mixed into PLA matrix PEG:PLA composite. composite material saw 9% upon heating, corresponding loss capacity. mPEG/PLA co‐polymers were found completely homogeneous thermally stable even when heated above its phase transition temperature, no observable leakage, demonstrating superiority chemical linking strategies ensuring stability.
