Abstract

original image

Inspired by natural nacre, layered composites based on graphene oxide (GO) and 10,12-pentacosadiyn-1-ol (PCDO) have been successfully fabricated. PCDO molecules are grafted onto GO sheets and cross-linked with each other, resulting in a superior toughness that is two times higher than that of the natural nacre.
