Abstract
Abstract Stiff yet room‐temperature self‐healing polymers are designed using molecularly engineered hydrogen bonds (H‐bonds). However, they often suffer from high brittleness, moisture sensitivity, and limited functionality. To overcome these challenges, high‐performance biomimetic nanocomposites inspired by inverse nacre structures are developed. A layered boron nitride nanosheet (BNNSs) skeleton is embedded within a previously synthesized room‐temperature self‐healing glassy polyurethane network, leveraging a solvent exchange‐induced self‐assembly strategy. This approach resolved the problem of BNNSs agglomeration and reconstructed robust yet dynamic noncovalent interfacial interactions, maximizing the…
