Hydration and dynamic state of nanoconfined polymer layers govern toughness in nacre-mimetic nanocomposites.
Advanced Materials (Deerfield Beach, Fla.), 2013•europepmc.org
Biological high-performance composites inspire to create new tough, strong, and stiff
structural materials. We show a brittle-to-ductile transition in a self-assembled nacre-inspired
poly (vinyl alcohol)/nanoclay composite based on a hydration-induced glass-to-rubber
transition in the 2D-nanoconfined poly (vinyl alcohol) layers. The findings open routes to
design dissipative toughening mechanisms to combine stiffness and strength in
nanocomposites.
