Laser Treatment Boosts Conductivity in Printed Graphene

Facebook X LinkedIn Email
AMES, Iowa, Sept. 19, 2016 — Treating inkjet-printed, multilayer graphene electric circuits and electrodes with a pulsed-laser process improves electrical conductivity of the graphene without damaging paper, polymers or other fragile printing surfaces. The discovery of this technology could lead to low-cost applications for printed graphene electronics. Researchers at Iowa State University developed a computer-controlled pulsed laser technology that selectively irradiates inkjet printed reduced graphene oxide (RGO). The treatment removes ink binders and reduces graphene oxide to graphene, physically stitching...Read full article
