▎ 摘  要

NOVELTY - Screen-printable ink comprises nano graphene platelets, polymer containing aniline monomeric units, and /-1 solvent. USE - Screen-printable ink for composite material used for electrode in capacitor (all claimed) used for gas sensor applications. ADVANTAGE - The ink preparation process is simple. A supercapacitor with excellent cyclic stability and high capacitance can be produced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of screen-printable ink which involves providing a dispersion of partly exfoliated nano graphene platelets in solvent, providing a polymer which contains aniline monomeric units and is soluble in the solvent, optionally providing a binder, and combining the products of previous steps; (2) composite material deposited on a substrate by using screen-printable ink; (3) application of composite material in capacitors; (4) electrode comprising a composite material deposited on a substrate; and (5) preparation of electrode which involves preparing screen-printable ink, providing a substrate, depositing the screen-printable ink onto the substrate, and partly removing the solvent.
