Abstract

Graphene-derived materials are attractive components in conductive inks for printed and flexible electronics. Here, the authors report a facile and scalable synthesis of mildly oxidized graphite and its formulation into screen-printable inks. The screen-printed electrodes exhibit sheet-resistance below 1 Ω/sq after rolling-compression, with a compressed film thickness of ≈3 μm and line-width resolution below 100 μm. The method, described herein, can be used without the need for substrate-limiting post-printing treatments, such as high-temperature annealing, photonic annealing, or chemical reduction. The approach is applicable to any arbitrary and heat-sensitive substrate, including plastic and paper, and is both highly cost-effective and suitable for roll-to-roll printing of a wide range of devices.
