Carbon electrodes are widely used for battery and electrolysis due to wide potential window and chemical stability. The carbon electrode made from carbon material ink using printing process is expected as electrode with low cost and large area. Therefore, we have developed carbon material inks and printed electrode by combining micro-wave treated graphite oxide (MwGO) and screen-printing method. However, the MwGO electrodes exhibited low water resistance. Cellulose nanofiber is mixed into the MwGO ink to improve water resistivity. As a result, increase in water resistance is achieved with maintaining electrical conductivity. [ABSTRACT FROM AUTHOR]
