Abstract

A novel method capable of the rapid fabrication of cellulose nanofiber (CNF)-based supercapacitors using a femtosecond laser is demonstrated. When high-repetition femtosecond laser pulses were scanned onto the surface of a CNF film, a black-colored double-tracked structure was fabricated in the vicinity of the laser ablated groove. The black structure exhibited electrical conductivity, and was composed of graphitic carbon. By utilizing the electrically conductive graphitic carbon as electrodes with an electrolyte solution between the groove, the fabricated double-tracked structure exhibited capacitive properties.
