An initial study on a simple and inexpensive method to form an Ir0.4Ru0.6-oxide (MMO) coating onto high-area plasma functionalized multi-walled carbon nanotubes (f-MWCNTs) at the bench-scale for possible supercapacitor (SC) applications is presented. f-MWCNT electrodes are prepared in a two-step process combining the growth of MWCNTs directly onto a 316 stainless steel mesh by thermal-chemical vapour deposition (t-CVD), followed by the addition of oxygen-containing functionalities to their surface by plasma functionalization. The plasma functionalization step is done to: (i) improve electrode wettability and (ii) improve capacitive properties through the addition of pseudocapacitive oxygen functionalities. A simple dip-dry method is then employed to coat the f-MWCNTs with the desired MMO coating (Ir0.4Ru0.6-oxide) prepared initially in a liquid precursor mixture. f-MWCNT electrodes are suspended and dipped into the precursor then heated in air to evaporate the solvent while building the oxide layer. The resulting MMO/f-MWCNT electrode exhibits excellent stability in 4mol/L KOH electrolyte, yielding larger specific capacitance values than those obtained on bare f-MWCNT electrodes; at a charging/discharging current density of 0.5mAcm(-2), the MMO/f-MWCNT and f-MWCNT electrodes achieve specific capacitances of 664 +/- 7 and 190 +/- 30Fg(-1) in a 3-electrode cell, respectively. The MMO/f-MWCNT electrodes show good rate capability performance up to 10mAcm(-2) and excellent stability.
