▎ 摘　　要

NOVELTY - A resin composition comprises a polyacrylate resin, 8-62 wt.% silica particles, and 1-8 wt.% multilayer graphene. The resin composition comprises 15-62 wt.% silica particles and multilayer graphene in total. USE - Resin composition is used for forming elastomer material in the form of sheet (all claimed). Uses include but are not limited to material for antenna substrate adapted to automobile, aircraft, domestic electric appliance, construction machine and wearable device, sealing material for small-sized and thin-walled package, printed wiring board material, optical communication module, millimeter wave radar, electromagnetic wave shield, smartphone, car navigation system, power device, etc. ADVANTAGE - The resin composition provides elastomer material having excellent mechanical property including tensile breaking stress, tensile breaking strain, stretchability and toughness, and dielectric property including large dielectric constant and small dielectric tangent. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: an elastomer material, which comprises the resin composition; and a dispersion liquid, which comprises an acrylate monomer, silica particles and multilayer graphene.
