Document Type and Number:
Japanese Patent JP7274617
Kind Code:
B2
Abstract:
A method of calculating a dielectric constant and a dielectric loss of a polymer material including the following steps is provided: providing a polymer having an optimized molecular geometry; analyzing a dipole moment autocorrelation function of the polymer having the optimized molecular geometry; fitting the dipole moment autocorrelation function of the polymer having the optimized molecular geometry via a relaxation function to obtain a corresponding fitting function; calculating a static permittivity of the polymer having the optimized molecular geometry; and obtaining a complex permittivity spectrum via the fitting function and the static permittivity, so as to calculate a corresponding dielectric constant and dielectric loss of the polymer having the optimized molecular geometry.
