▎ 摘　　要

NOVELTY - A high-performance composite dielectric elastomer comprises a rubber matrix and a modified filler, where the modifier used by the modified filler is a coupling agent containing an aromatic ring. USE - High-performance composite dielectric elastomer used for energy converter in dielectric drive mode or power generation mode (all claimed). ADVANTAGE - The high-performance composite dielectric elastomer has excellent dielectric properties and durability, high energy density, and fast response. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the high-performance composite dielectric elastomer, which involves mixing the modified filler with the rubber matrix, and vulcanizing the mixture.
