Electromechanical properties of ferroelectric polymers: Finsler geometry modeling and a Monte Carlo study

Polyvinylidene difluoride (PVDF) is a ferroelectric polymer characterized by negative strain along the direction of applied electric field. However, electromechanical response mechanism PVDF remains unclear due to complexity hierarchical structure across length scales. As described in this letter, we employ Finsler geometry model as new solution aforementioned problem and demonstrate that deformations observed through Monte Carlo simulations on 3D tetrahedral lattices are nearly identical those real PVDF. Specifically, simulated mechanical deformation polarization similar experimentally.
