▎ 摘　　要

NOVELTY - Quickly and controllably preparing flexible graphene electrode comprises adding graphene powder into absolute ethyl alcohol, and ultrasonically processing to obtain uniformly dispersed graphene/anhydrous ethanol suspension solution; fixing base paper of one section of double-faced carbon conductive adhesive tape downward; exposing adhesive conductive adhesive; dropping graphene/absolute ethyl alcohol suspension solution to part of double-sided carbon conductive adhesive tape exposed out of adhesive conductive adhesive; and using electric hair dryer to dry anhydrous ethanol. USE - The flexible graphene electrode is useful in preparing metal micro-nano structure, electrochemical biosensor, or portable electrical analysis and electronic device (claimed). ADVANTAGE - The method is convenient and fast, economical, environment-friendly and non-toxic, and can prepare various metal micro-nano structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing metal micro-nano structure using flexible graphene electrode.
