Carbon nanowalls/vertical graphene grow vertically on substrates. To calculate the specific capacitance from cyclic voltammetry measurement, I wanted to know how the mass of the samples can be calculated. Can someone provide any reference regarding that?
Dear Subrata,
I would suggest that you measure the complex impedance, using Impedance Analyser. Cyclic voltammetry is related to this quantity, but in my view, there is a number of unresolved issues. The measured impedance is usually frequency dependent and analysis leads to the measured "bulk" GEOMETRICAL capacitance. By knowing the geometry (which I do not know at this stage: where are the electrodes, what is their spacing, how many singular nanowires they cover, etc.), the wall thickness can be deduced.
With regards
Petr
Dear Dr. Viscor,
Nice to get reply from you. I'm agree with you and I already started towards your suggested direction.
Thank you very much for your valuable comment.
With respect,
Subrata
