This paper reports a simple bottom-up method that can controllably fabricate 2D hexagonally oriented and randomly distributed (CdCl2H2O)-H-. nanorods on mica surfaces. The as-formed nanorod assemblies have been successfully replicated into various matrixes, including gold, poly(dimethylsiloxane), and polyurethane. Thus, this method is compatible with soft-lithography towards further applications.
