TL;DR: Graphene-based, flexible, transparent heaters based on large-scale graphene films synthesized by chemical vapor deposition on Cu foils show sheet resistance as low as ∼43 Ohm/sq with ∼89% optical transmittance, which are ideal as low-voltage transparentheaters.

TL;DR: This work demonstrates the implementation of a laminated ultrathin CVD graphene film as a stretchable and transparent electrode for supercapacitors and demonstrates excellent frequency capability with small time constants under stretching.

TL;DR: In this paper, polypyrrole (PPy)/carbon nanotube (CNT) composite electrodes are fabricated on ceramic fabrics for electrochemical capacitor applications, and the morphology of the PPy-CNTs on the ceramic fabrics is confirmed by SEM and TEM, and electrochemical characteristics are investigated by cyclic voltammetry and galvanostatic charge-discharge tests.

TL;DR: This work enhances the transfer efficiency of the large-area graphene films on a substrate with arbitrary thickness and rigidity and performs a theoretical multiscale simulation from continuum to atomic level to compare the mechanical stresses caused by the R2R and the hot-pressing methods.

TL;DR: The hybrid electrode offers an effective and simple route for achieving a sheet resistance as low as ∼4 Ω per square with ∼78% optical transmittance and it is demonstrated that transparent flexible heaters based on the hybrid conductive films could be used in a vehicle or a smart window system.
