From Nanowheat to Nanograss: A Preparation Method to Achieve Free Standing Nanostructures Having a High Length/Diameter Aspect Ratio

Abstract The controlled fabrication of free standing, none collapsing nanostructures with a high length/diameter aspect ratio is reported. Usually these nanostructures synthesized using a template‐based method tends to collapse into wheat like structures using common techniques to separate the nanostructures from the template. Based on a novel process to inhibit the mechanism of collapsing nanostructures synthesized by template‐based deposition, nanograss‐like, and free standing nanostructures are obtained.
