Although research in bioinspired nanocomposites is delivering mechanically superior nanocomposite materials, there remain gaps in understanding some fundamental design principles. This article discusses how the mechanical properties of nacre‐mimetic polymer/nanoclay nanocomposites with nanoconfined polymer layers are controlled by the thermo‐mechanical polymer properties, that is, glass transition temperature, T g, using a series of poly(ethylene glycol methyl ether methacrylate ‐co‐N , N ‐dimethylacrylamide) copolymers with tunable T g from 130 to −55 °C. It is elucidated that both the type of copolymer and the nanoconfined polymer layer thickness control energy dissipation and inelastic deformation at high fractions of reinforcements in such bioinspired nanocomposites.
