Abstract

Here, we investigate the formation of inkjet-printed graphene oxide (GO) droplets with different flake size. It is shown that the size of GO flakes has strong influence to the drop morphology and can be used to control the CRE. The CRE was eliminated gradually with increased mean GO flake size (from 0.68 to ~ 36 µm). The result suggests a new strategy to control the CRE, and our observation about the morphology of inkjetprinted droplets with different flake size will be very effective to print uniform two-dimensional materials based patterns.
