▎ 摘 要
NOVELTY - The preparation method of metamaterial capacitor material involves preparing negative dielectric layer material graphene/polyvinylidene fluoride composite material, and preparing epoxy resin coating on the graphene/polyvinylidene fluoride composite material. USE - The method is useful for preparing metamaterial capacitor material. ADVANTAGE - The method enables simple preparation of metamaterial capacitor material with high frequency and high dielectric constant value of 100 MHz to 1 GHz.
