NOVELTY - The method involves setting (S1) the model parameters to calculate the number of graphene nanosheets in the piezoelectric polymer simulation space. The piezoelectric polymer simulation space is generated (S2) according to the model parameters, and graphene nanosheets are randomly generated in the piezoelectric polymer simulation space. The number of grids is set (S3) in the piezoelectric polymer simulation space, grid lines for the piezoelectric polymer simulation space is drawn along the three coordinate axes that are perpendicular to each other in the three-dimensional space, and the intersection of the grid lines are recorded as grid points. The effective dielectric constant of the graphene doped piezoelectric polymer matrix composites is obtained, so which is taken into account the polar phase transition and interface polarization caused by the addition of graphene nanosheets. USE - Method for constructing dielectric constant model of graphene-doped piezoelectric polymer-based composite material.
