A facile approach to preparation of nanostripes on the electropolished aluminum surface

Ordered nanostripe structures on aluminum surface were obtained by electropolishing unannealed polycrystalline aluminum sheet in the C2H5OH and HClO4 solution [V(C2H5OH)/V(HClO4)=4:1] at room temperature for 10 s, with the cell voltage at 20 V.
