Poly(styrene‐alt‐maleic anhydride) ionic salt functionalized reduced graphene oxide doped with rare earth ions for anti‐corrosion performance enhancement

A novel organic–inorganic nanocomposite material of rare earth ions/ poly(styrene‐alt‐maleic anhydride) ionic salt/ reduced graphene oxide ( Re 3+ /SMA‐Is/rGO) was prepared successfully. Poly(styrene‐alt‐maleic anhydride) ionic salt functionalized reduced graphene oxide (SMA‐Is/rGO) was processed with two methods of π–π conjugation and ionization; rare earth ions (Re 3+ = La 3+ , Ce 3+ Pr 3+ ) was doped on the surface of rGO by physical mixing....
