Rational assembly of anisotropic nanoparticles in polymers is a strategy for obtaining mutifuncional nanocomposites with superior properties. Many high aspect ratio anisotropic nanomaterials form stable liquid crystals, and their order in colloidal form can be translated into ordered solid polymer nanocomposites. Inspired by the structure of nacre (mother of pearl), we process highly aligned and layered polymer nanocomposites of 2D nanomaterials such as graphene oxide (GO) and reduced graphene oxide (rGO). The anisotropic nanocomposites show a host of superior multifunctional properties and find application in anti-corrosion coatings, electromagnetic interference shielding, food packaging, and scratch resistant surface. We try to understand the mechanism of self-assembly of 2D nanomaterials from stable liquid crystalline colloidal dispersions into solid ordered nanocomposites, and to explore their advanced anisotropic properties for various engineering applications.
