Mechanically Robust and Self-Healable Superlattice Nanocomposites by Self-Assembly of Single-Component "Sticky" Polymer-Grafted Nanoparticles.


PMID 26017026

Abstract

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 multi-valent 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.
