Build the Structure of Ordered Vertically-Aligned Codoped Carbon Nanowires Array for Supercapacitor.

We report an ingenious yet efficient method to fabricate ordered vertically-aligned Nitrogen- and Sulfur- codoped carbon nanowires (NS-CNWs) array by direct carbonization of the finely designed copolymer. The as-prepared vertical aligned NS-CNWs with unique electronic feature and very narrow diameters facilitate the ions diffusion to further exhibit an ideal electrochemical properties (243.0 F·g-1 at the current density of 0.1 A·g-1) and excellent cycle stability (10,000 cycles) when applied to supercapacitor electrode. The controllable design and copolymerization of conducting polymers that can provide doped carbon nanowires array electrodes having high surface area with controllable components and uniform dimensions in a neat way, providing more flexibility to tailor the carbon based electrodes toward specific applications.
