**Abstract**
 Nanopatterning has attracted much attention because of its growing use in designing nanoelectronic and optoelectronic devices. Development of a facile route to nanopatterning is a persistent goal in nanotechnology. Originating from positively charged polyethyleneimine (PEI) and negatively charged poly(4-styrenesulfonate) (PSS), we successfully designed separable nanoflake patterning using layer-by-layer self-assembly technique by sequential adsorption of PEI and PSS. The morphology and size of the nanopatterning can be controlled by adjusting the number of bilayers in the film. Electrochemical measurements reveal that the (PEI/PSS)n nanoflakes have good electroactivity and permeability for the electrolytes undergoing redox reaction. By controlling the distribution of surface charges on substrates, nanopatterning can be facilely achieved by self-assembly method. 10 Refs.
