Corrosion protection of complex surface is an active area research due to its importance commercial applications such as electrochemical fabrication. However, conventional coatings exhibit limited conductivity, thermal stability, and durability are thus not suitable. Recent work has shown the potential graphene, a two-dimensional carbon allotrope, for corrosion protection. The studies, however, themselves simple planar geometries that provide insight in applicability relevant morphologies mesh electrodes roughened surfaces. We here study ability tubular graphene (TG) on Ni-wires model system geometries. TG-covered Ni wires approximately 50 μm diameters were produced by annealing cellulose acetate (CA) Ni. high quality TG coating was confirmed Raman spectroscopy, scanning electron microscopy, electrical measurements. show layer number could be controlled adjusting CA membrane quantity. found direct relation between degree inhibition with variation number. increase layers enhance acidic, basic, marine environments, which shows our approach future applications.
