Abstract
A simple heating-cooling procedure is employed to make pure polar γ-PVDF thin films. By controlling the relaxation state of the crystals, pure γ crystals are induced by two kinds of mechanism including self-seeding and self-nucleation upon cooling within 30 min. The methodology paves a new way for PVDF homopolymers in flexible ferroelectric device applications.
