Abstract

In this work, the experimental results of the graphite oxide (GO) reduction with laser irradiation are presented. GO films on a flexible polycarbonate substrate were produced using a modified Hummers method. Experiments were conducted using a picosecond laser. The pulse energy and beam scanning speed were varied during the reduction experiments. All experiments were performed in air. Raman spectroscopy measurements and electrical resistance measurements were implemented on the laser treated GO samples. Scanning electron microscopy (SEM) was used for morphology inspection. Experiments results showed that for certain range of laser microfabrication parameters, electrical properties, suitable for electronics applications can be achieved in reduced GO films. Such laser-modified GO films are intended to be used as contacts for flexible supercapacitors.
