Abstract
Screen-printable conductive inks have been widely applied to prepare electrodes for electrochemical sensing. These inks generally consist of conductive metal or carbon particles, solvents, and polymeric binders. Low-cost, carbon-based, screen-printable conductive inks are especially popular. However, screen-printed carbon electrodes (SPCEs) must often be modified after they are printed to impart the necessary characteristics (e.g., sensitivity, selectivity, stability) for the desired application. For example, nitrogen-doping of SPCEs, especially in ways that introduce pyridinic or pyrrolic nitrogen species, can impart electrocatalytic properties towards reduction of O2, H2O2, and CO2. While our previous work done by C. Ogbu focused on modifying SPCEs or graphitic carbon starting material, here we investigate an alternative approach to introduce surface nitrogen species on SPCEs by utilizing a pyridinic nitrogen-containing polymer (poly(4-vinylpyridine), P4VP) in the ink formulation. In this work, the effects of important ink (carbon content, binder composition) and printing (mesh size) parameters on SPCE properties and electrochemical performance are evaluated.
