Nanostructured Graphene Composite Papers for Highly Flexible and Foldable Supercapacitors

Abstract
Reduced graphene oxide (rGO) and polyaniline (PANI) assemble onto the surface of cellulose fibers (CFs) and into the pores of CF paper, to form a hierarchical nanostructured PANI‐rGO/CF composite paper. Based on these composite papers, flexible and foldable all‐solid‐state supercapacitors are achieved.
