▎ 摘　　要

Herein, the fabrication of a simple, low-cost, disposable, and flexible graphene (GP) electrochemical electrode by inkjet printing of the aqueous graphene oxide (GPO) dispersion ink was investigated. In terms of conductivity enhancement, the inkjet-printed GPO chip was chemically reduced, and exhibited high electrochemical response, reactivity, and stability. The electrode is a promising candidate for electrochemical applications.
