▎ 摘  要

NOVELTY - The electrode has a first component formed with a conducting polymer of poly-3-4-ethylenedioxythiophene, where the conducting polymer of poly-3-4-ethylenedioxythiophene is prepared from a poly-3-4-ethylenedioxythiophene-poly-styrenesulfonate dispersion. A second component is formed with exfoliated graphene dispersion with graphene flakes or micro sheets that are derived directly from graphite, where the poly-3-4-ethylenedioxythiophene-poly-styrenesulfonate dispersion is deployed to the graphene at a composite weight ratio between 1:1 and 4:1. USE - Composite electrode for electronic devices. Uses include but are not limited to touch panels, plasma displays, flat panel displays, solar panels and energy efficient windows. ADVANTAGE - The electrode improves transparency, flexibility and sheet resistance for the electronic devices. DETAILED DESCRIPTION - An INDEPENDENT CLAIMS is also included for a method for fabricating a composite electrode for electronic devices. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of a plot of transmittance versus wavelength of a composite electrode. aStep for preparing a poly-3-4-ethylenedioxythiophene-poly-styrenesulfonate dispersion bStep for preparing exfoliated graphene dispersion cStep for subjecting poly-3-4-ethylenedioxythiophene-poly-styrenesulfonate dispersion and exfoliated graphene dispersion dStep for subjecting a resulting article to organic solvent treatment eStep for preparing thin film
