Abstract

One of the main areas of improvement in capacitive deionization technologies is the materials used for electrodes which have very specific requirements. In the present work, a wide range of material characterization techniques are employed to determine the suitability of a multiwall carbon nanostructure thin film as electrode material. The electrical, mechanical, surface and wetting characteristics are studied proving the membrane highly conductive (σ=7.25 103 S/m), having competitive electro-sorption capacity (11.7 F/g at 10 mV/s) and surface area (149 m2/g), strain rate dependent mechanical properties and hydrophobic wetting behavior.
