Abstract:After billions of years of evolution, the natural nacre, consisting of almost 95 vol% inorganic plates (aragonite calcium carbonate) and 5 vol% organic macromolecules (elastic biopolymer), shows a unique combination of the remarkable strength and toughness. Inspired by both the structural and mechanical characteristics of the nacre, scientists have explored a variety of approaches to mimic the natural nacre and build the nacre-like layered composites. Herein, we focus on the interface design of the bioinspired layered materials composed of varying primitive materials based on our recent research progress, including: the layered materials of the highest performance based on the flattened double-walled carbon nanotubes (network (Q.F. Cheng, et al, Adv. Mater. 2012, 24, 1838-1843), the ultratough artificial nacre based on the graphene oxide (GO) sheets through (Q.F. Cheng, et al, Angew. Chem., Int. Ed. 2013, 52, 3750-3755), and the robust hydrogel by introducing the two-dimensional nanoclay into the poly(N-isopropylacryamide) (Q.F. Cheng, et al, Angew. Chem., Int. Ed. 2012, 51, 4676-4680). We demonstrate that these interface design strategies are significant for constructing high performance bioinspired layered materials as well as offer innovative insights into production of functional artificial materials.
