Original Abstract

For industrial-scale electrochemical applications of renewable energy routes such as electrochemical water splitting or supercapacitors, there is a huge need for flexible, durable, and large-area electrodes. In this study, flexible and conductive poly(lactic acid)/graphite composite films, with a high mass percentage (similar to 64%) of conductive graphitic material, are prepared without specialized equipment and can be used as stable electrodes in aqueous solutions. These films can be used as a substrate for the hydrogen evolution reaction, which is demonstrated in this study by spray coating with molybdenum(IV) sulfide. Finally, the films are manipulated to construct a flexible solid-state supercapacitor device that can withstand a bending angle of 120 degrees without any change in performance. The geometric characteristics of the electrodes can be manipulated to any shape and size, and as such, they are scalable to large areas.
