  "abstract": "Covalent adaptable networks (CANs) represent a critical advancement in sustainable polymers, yet their deployment is frequently constrained by a trade-off between high thermal service limit and on-demand degradability. Herein, we report an organic-inorganic hybrid polymer architecture that decouples thermomechanical robustness from chemical responsiveness. By integrating rigid polyhedral oligomeric silsesquioxane (AcryloPOSS) nanoclusters into a dynamic lipoic acid-based CAN-type matrix, the POSS cages function as steric nanoscale shields that restrict polymer chain mobility. This structural confinement yields a high activation energy for disulfide exchange (204.9 ± 22.5 kJ mol-1), thereby suppressing macroscopic creep and maintaining network integrity up to 250°C, matching the performance of non-degradable commercial thermosets. Furthermore, the hybrid network exhibits chemical stability over a wide pH range yet undergoes complete dissolution in highly alkaline solutions within 24 hours, decomposing into the building blocks of the hybrid polymer. Utilizing digital light processing 3D printing, we demonstrate a dual-curing strategy to fabricate geometrically complex, high-resolution polymeric objects that balance exceptional durability with closed-loop end-of-life deconstructability.",
