▎ 摘　　要

NOVELTY - A hybrid composition comprises a resin matrix used as binder, and a filler dissolved in a solvent. The filler comprises a flaky metal alloy powder having electromagnetic interference shielding and absorption characteristics, and carbon-based graphene powder or elliptical nanodiamond powder having an average particle size of 4-5 nm and a specific surface area of 300-360 m2/g. USE - Hybrid composition is used for ink compositions used for forming composite sheets, and for injection-molding compositions (all claimed). ADVANTAGE - The hybrid composition has excellent electromagnetic-wave shielding property, heat resistance, and thermal conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) paste-form ink composition obtained by dispersing the hybrid composition in a bead mill, removing bubbles, and controlling the viscosity; (2) composite sheet; and (3) injection-molding composition obtained by mixing polycarbonate or acrylic resin with the hybrid composition, and forming pellets.
