Highly porous and easy shapeable poly-dopamine derived graphene-coated single walled carbon nanotube aerogels for stretchable wire-type supercapacitors

A nitrogen-doped graphitic layer-coated 3D NCA exhibiting an ultra-high SSA, remarkable mechanical robustness, and excellent aqueous wettability was produced. A WTSC with electrodes made from μCFs decorated by this 3D pDA-Gr NCA was also fabricated by helically wrapping around a PU wire; this WTSC exhibits an ultra-high capacitance, high energy density, and excellent stability under tensions of up to 100% strain.150
