▎ 摘　　要

NOVELTY - Preparing high dielectric and low loss material based on synergistic effect of capacitance and inductance comprises (i) mixing graphene with different mass fractions and mixing with polyvinylidene fluoride, pulverizing and drying to obtain first mixed powder and second mixed powder, where the first mixed powder has capacitance characteristics, and the mass fraction of graphene is 0-6 wt.%, and second mixed powder has inductance characteristics, and the mass fraction of graphene is 6-18 wt.%, and (ii) pressing the first mixed powder into a shape to obtain single-layer material, and(iii) pouring the second mixed powder onto the single-layer material obtained in the step (ii), pressing and forming to obtain high-dielectric and low-loss material with double-layer structure. USE - The method is useful for preparing high dielectric and low loss material based on synergistic effect of capacitance and inductance. ADVANTAGE - The material has high dielectric, and low loss; and is good for mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for high-dielectric, low-loss material based on synergistic effect of capacitance and inductance.
