Hi I am working on electrochemical sensing applications. The ink (slurry) composition I used in as follows;
5 mg material + 850 microL Isopropanol + 100 micro L Milliq water + 50 microL nafion (5% per fluorinated ).
I am not sure how much should be the amount of nafion we have to use. Is it more concentration of nafion affects current peaks ? I am not getting peaks with some of the materials. What should be the ideal or optimum loading of nafion we should use for obtaining current peaks? How nafion affects the current peaks in cyclic voltametry?
