Abstract

A simple two-step (metal deposition and subsequent heating) approach to fabricate controllable biaxial and uniaxial nanowrinkles and nanopetals based on shape memory polymer (pre-stressed polystyrene) sheets is presented. Wavelengths of wrinkles can be tuned from 300nm to 800nm by controlling the thickness of deposited metal. We demonstrate utility of these nano structures with ready integration into microchannels and effectiveness in surface enhanced sensing.
