Effect of porosity variation on the electrochemical behavior of vertically al…

Abstract. Electrochemical charge storage characteristics of vertically aligned multi-walled carbon nanotubes (MWCNTs) as a function of varying diameter and spacing are reported. It was observed that the specific capacitance of the MWCNTs increased as both diameter and inter-tube spacing decreased. The MWCNT films with 230 nm inter-MWCNT spacing exhibited specific capacitance of 228 F/g versu…
