In two-dimensional printed electronics, the main task of graphene ink is to be deposited onto a substrate surface to form lines, films, electrodes, or conductive patterns. Whether the pattern can be successfully formed mainly depends on whether the ink can spread stably, dry uniformly, and form ...
At first glance, graphene ink may seem straightforward: graphene has good electrical conductivity, flexibility, and chemical stability, so can’t we simply add graphene powder to a solvent, disperse it by ultrasonication, and obtain a conductive ink?
The emerging field of printed electronics requires a suite of functional materials for applications including flexible and large-area displays,radio frequency identification tags, portable energy harvesting and storage,biomedical and environmental sensor arrays,and logic circuits. To enable ...
