▎ 摘　　要

NOVELTY - The method involves obtaining fineness ratio of a graphene component. Electrical properties of a constituent material. Different graphene content of an orientation consistent graphene-polymer porous nanometer composite material is obtained. An equivalent alternating conductive and dielectric prediction model is established. Material parameters are obtained. A residual parameter of three prediction models is obtained. Alternating current (AC) conductivity of the orientation consistent graphene-polymer porous nanometer composite material is obtained. USE - Graphene porous nanometer composite material alternating electrical performance prediction method. ADVANTAGE - The method enables determining maximum angle between graphene materials, obtaining microstructure parameters without affecting electrical performance of a product, and re-establishing the prediction model after checking a prediction result that is close to an experimental value. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing relationship between graphene content and alternating frequency. '(Drawing includes non-English language text)'
