Modeling the Piezoelectric D₃₃ Coefficient of Voided Charged Polypropylene Film by Finite Element Method

Abstract:

Voided charged Polypropylene films have very large piezoelectric d33 coefficient and have emerged as a kind of novel electromechanical transducer materials. In this paper, we propose the analysis method of piezoelectric d33 coefficient of voided charged Polypropylene film by finite element model. The very flat voids are simulated by the hollow oblate tetrakaidecahedron and periodic boundary conditions are implied. The electrostatic analysis is conducted and elastic deformation is solved by using ANSYS FE software. Qualitative analysis is presented for the piezoelectric d33 coefficient, and several influencing parameters are discussed, including void geometry and charge density. This finite element model can provide help in the analysis and design of voided charged polymer film with complex microstructures.
