▎ 摘　　要

NOVELTY - A planar solid-state reference electrode preparation method involves printing silver paste-potassium chloride agar conductive paste on polyester sheet by screen printing technology, protecting from light, drying, adding gold nanoparticles/graphene oxide suspension on surface of silver-potassium chloride conductive layer, protecting from light, drying, adding PVC solution in dropwise, protecting from light and drying at room temperature. USE - Method for preparing planar solid-state reference electrode. ADVANTAGE - The method enables preparing planar solid-state reference electrode with long-term stability and small potential impact on environmental factors such as inorganic salts and acidity in a rapid manner at low cost.
