Chemically cross-linked cellulose nanocrystal aerogels represent a versatile and universal substrate on which to prepare lightweight hybrid materials. In situ incorporation of polypyrrole nanofibers, polypyrrole-coated carbon nanotubes, manganese dioxide nanoparticles in the gives flexible 3D supercapacitor devices with excellent capacitance retention, low internal resistance, fast charge-discharge rates.
