Chitosan Nanostructures with Controllable Morphology Produced by a Nonaqueous Electrochemical Approach

Chitosan nanowires (see figure) are successfully fabricated on a stainless steel substrate by a nonaqueous electrochemical route that does not require a template, catalyst, or surfactant. The nanoscale morphology of the final products – nanoflakes, nano wires, nanobelts, nanorods, and nanotubes – can be easily tuned by controlling the experimental conditions. This approach is ideal for exploring large‐scale industrial production of chitosan nanomaterials.
