Copyright 2012 American Physical Society. The following article appeared in Physical Review Letters, 108:8, http://link.aps.org/doi/10.1103/PhysRevLett.108.087802

Abstract: Using first-principles simulations, the authors identify the microscopic origin of the nonlinear dielectric response and high energy density of polyvinylidene-fluoride-based polymers as a cooperative transition path that connects nonpolar and polar phases of the system. This path explores a complex torsional and rotational manifold and is thermodynamically and kinetically accessible at relatively low temperatures. Furthermore, the introduction of suitable copolymers significantly alters the energy barriers between phases providing tunability of both the energy density and the critical fields.
