| Abstract Scope |
Stretchable supercapacitors (SCs) have attracted significant attention in developing power-independent stretchable electronic systems due to their intrinsic energy storage function and unique mechanical properties. In this talk, we will present a facile method to fabricate arbitrary-shaped stretchable electrodes via direct 4D printing of conductive nanocomposite made of reduced graphene oxide (RGO), carbon nanotube (CNT), and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The electrode patterns of an arbitrary shape can be deposited onto prestretched substrates by aerosol jet printing, then self-organized origami (ridge) patterns are generated after releasing the substrates from holding stretchers due to the mismatched strains. The stretchable electrodes demonstrate superior mechanical robustness and stretchability without sacrificing its outstanding electrochemical performance. The proposed method paves avenues for scalable manufacturing of future energy-storage devices with controlled extensibility and high electrochemical performance. |
