Facile fabrication of ferroelectric poly(vinylidene fluoride) thin films with pure γ phase

A simple heating-cooling procedure is employed to make pure polar gamma-PVDF thin films. By controlling the relaxation state of the crystals, pure gamma 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.

A simple heating-cooling procedure is used to fabricate pure polar gamma-PVDF thin films. The pure gamma crystals are induced by controlling the relaxation state of the crystals, through self-seeding and self-nucleation mechanisms within 30 minutes. This methodology provides a new pathway for the application of PVDF homopolymers in flexible ferroelectric devices.
