摘要

Analytical expressions for the pyro- and piezoelectric coefficients of nonlinear optical polymer electrets with incorporated chromophore groups are obtained. The calculations are based on exactly solvable model for local electric field experienced by a chromophore in the anisotropic polarizable deformable environment, suggested earlier by the author. Using a self-consistent procedure the macroscopic frozen-in polarization of the material is determined, and on this basis four key contributions to the pyro- and piezoelectric coefficients are discussed.
