▎ 摘 要
NOVELTY - A composite material comprises a polymeric material and a hydrazine-reduced graphene oxide. USE - Composite material for manufacturing capacitor device such as a memory device, a capacitor, a transistor or a diode (all claimed), various high dielectric permittivity components and high charge storage capacitors. ADVANTAGE - The composite material has high dielectric permittivity, low dielectric losses, low percolation threshold, better electrical or chemical properties, improved conductivity, better chemical interface properties, improved charge flow, or better processability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing a composite material (2) a capacitor device (3) a method for manufacturing capacitor device. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a capacitor device. Substrate (101) Electrode (106) Dielectric layer (112) Second electrode (116)
