Optimizing graphene oxide reduction via laser irradiation
The present report discusses a single step method to reduce graphene oxide via laser irradiation. A computer numerically controlled laser engraver equipped with a 450nm laser diode was engineered to conduct this research. Reduced graphene oxide samples were prepared on a polycarbonate substrate at various laser powers, scan speeds, and total energy deposition, in an attempt to optimize this single step reduction. The quality of the finished product was determined by two probe multimeter resistance measurements, and carbon to oxygen ratios given by X-ray microanalysis.
