▎ 摘　　要

NOVELTY - The reference electrode has a graphene containing a fluorine functional group treated with fluorine-benzene. The graphene is non-oxidized graphene or reduced graphene oxide (rGo). The fluorine-benzene treated graphene containing a fluorine functional group is a fluorine-benzene solution in which non-oxidized graphene powder or reduced graphene oxide powder is dispersed. USE - Reference electrode for ion measurement sensor. ADVANTAGE - The reference electrode for an ion measuring sensor is provided with improved reproducibility and reliability without exhibiting sensitivity to not only hydrogen ions present in a solution and also sodium ions, calcium ions, potassium ions. The reference electrode for an ion measurement sensor is manufactured by one printing and application. The reference electrode for an ion measuring sensor is easily manufactured by being compatible with a semiconductor manufacturing process for manufacturing the ion measuring sensor. The reference electrode for an ion measuring sensor is manufactured without being limited by equipment area. The reference electrode is provided for a micro-sized ion measuring sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a reference electrode manufacturing method for ion measurement sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the reference electrode for ion measurement sensor.
