I am trying to deposit graphene oxide film on steel electrode via drop casting (Article Electrochemical synthesis of layer-by-layer reduced graphene...

) and dry it in oven at 60 C. when i put this into H2SO4 and aniline aqueous solution for electrodepsition, graphene oxide is dissolve in electrolyte solution. Further drop casting GO on PANI and dry it. for electrochemical performance as i dip this in 1 M H2SO4 electrolyte solution then graphene again start dissolving in solution. so how i can deposit a good film of Graphene oxide?
