Hi researchers. I have deposited a polymer, PANI on Glassy carbon electrode by electrodeposition method. CV results of It showing only the oxidation peak taken in 100mM ferri+ferro solution in 0.1M KCl solution. Why is it so. how can I resolve it?
Dear Researchers
May be the solution is low-concentration. Perhaps can try several concentrations and parameters in CV to find the best results.
Please compare the two electrodes to see if you have successfully produced the polymer film on the GCE. Additionally, confirm that the optimization settings you utilized for your electrodeposition were adequate. If you do have the polymer, you could also try the drop-casting or chemical deposition methods; however, these would be challenging to use with monomer. Another issue is that you used a large amount of probe concentration. In reality, it would be advised to use 1–10 mmol L–1 of equimolar FFC. Thank you.
I used 3 techniques: monolayer deposition, layer-by-layer (LBL) and electrodeposition techniques—all the combination techniques used in CV. For the polymer electrode, I test the current resistivity and conductivity. If you use a monomer, you must control the parameter, especially the monomer concentration. There is a monomer that is very difficult to mix, dilution is needed. I am using higher concentrations because I want to check the suitable response for the enzyme. The enzyme was deposited in polymer layers. You can check the related results from my papers. I have published a series of polymer characterization.
