Reprocessable and Recyclable Cellulosic Network Polymers with Intrinsic Flame Retardancy via Dynamic Covalent Cross-Linking

). More importantly, the dynamic linkers enable efficient chemical depolymerization to recover monomers, thereby overcoming the limited chemical recyclability of prior cellulose materials. The combination of mechanical robustness, thermal and chemical resilience, flame retardancy, and circularity makes CAA-DDPNs a viable, eco-friendly alternative to conventional petroleum-based plastics.
