On the flexoviscous behavior in viscoelastic materials
  A phenomenological model on the relationship between viscoelasticity and flexoelectricity is proposed to address the electromechanical coupling under rheological processes in viscoelastic materials. Our theoretical studies show that some observed ferroelectric phenomena in certain viscoelastic materials, like polymer films, may not be intrinsic material behavior.
