Facile and Large-Scale Route to the Fabrication of CuO Nanosheets from a Lamellar Mesophase and Their Reversible Self-Assembly

Abstract

CuO and ZnO nanosheets were conveniently synthesized on a multigram scale under ambient conditions by using a surfactant lamellar mesophase as a soft template. The fabricated nanosheets were found to exhibit reversible self-assembling properties. By using the nanosheets as a basic building block and surfactants as structure-directing agents, highly ordered lamellar mesostructures were reassembled on the substrate.
