Nitrogen-doped graphene coupled with aligned polyaniline cores arrays (NG/PANI) has been successfully prepared by in-situ dilution polymerization. The polyaniline core arrays in situ grows on nitrogen-doped graphene nanosheets to form hierarchical NG/PANI hybrid nanosheets. Electrochemical measureme...
