▎ 摘　　要

NOVELTY - The method involves preparing a flexible substrate of an oxidation graphene ratic/carbon cloth. A silver/silver chloride layer is prepared by depositing a silver layer on the oxidized graphene/carbon cloth flexible substrate by electrochemical technique. A petal-silver chloride reference electrode is prepared by using an electrochemical chlorination method. Conductive hydrogel is utilized as an encapsulating film to encapsulate the graphene/carbon cloth petal-silver chloride electrode. A conductive hydrolytic/oxide/carbon graphene flexible electrode is prepared. USE - Method for preparing a flexible reference electrode used for detecting ethanol. ADVANTAGE - The method enables preparing a flexible reference electrode with high conductivity, stability and ion permeability and improving service life and electrode performance of the flexible reference electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for preparing a flexible reference electrode used for detecting ethanol. (Drawing includes non-English language text).
