A simple, scalable synthesis of mechanically robust and self‐healable superlattice nanocomposites is achieved through self‐assembly of single‐component “sticky” polymer‐grafted nanoparticles. The multivalent hydrogen‐bonding interactions between the nanoparticles provide strong cohesive energy, binding the nanoparticles into strong and tough materials. Furthermore, the dynamic hydrogen‐bonding interactions afford the formation of highly dynamic, self‐healing, and mechanochromic nanocomposite materials in the bulk.
