Two-step method for synthesizing polyaniline with bimodal nanostructures for high performance supercapacitors

The as-prepared polyaniline exhibits a bimodal morphology composed of a coral-like structure and a nanowire structure. A large specific capacitance of 689 F g−1 at 1A/g and retention of 613 F g−1 at 10 A/g is obtained for net polyaniline.397
