Realizing organic phase-change material networks with excellent recyclability while maintaining high latent heat still faces great challenges due to the difficult trade-off between network composition. Herein, and recyclable materials (RPCMs) were developed by integrating linear poly(ethylene glycol) (PEG) multimers as components dynamic covalent cross-linking polyurethane in a semi-interpenetrating polymer structure. The (54.7-145.0 J/g) can be readily tuned weight fraction of PEG molecular PEGs used RPCMs. RPCMs have recyclability/reprocessability activation energy 81.23-125.84 kJ/mol introducing disulfide bonds structure enabling adjustable mechanical stress (10.72-14.04 MPa) strain (7.40-266.22%), thermal reliability, stability. Efficient photothermal realized polydopamine particles RPCM matrix. management system photothermoelectric generator designed based on advantages efficient ability further demonstrated properties.
