摘要

Abstract

Poly(vinylidene fluoride) (PVDF)-based relaxor ferroelectric polymers incorporating groups with strong dipole moments can display multifunctional electrical responses and are highly promising for flexible electronics. Despite their evident advantages and years of research

achieving precise control over the dipole alignment and switching remains elusive

hindering further performance optimization. This study introduces a structural optimization strategy to modulate the multi-level structure of poly(vinylidene fluoride-

-trifluoroethylene-

-chlorofluoroethylene) (P(VDF-TrFE-CFE)) relaxor polymer. This approach enhances crystallinity

promotes chain orientation across both crystalline and amorphous regions

expands interplanar spacing and simultaneously introduces significant conformational disorder within nanosized pola

r domains. Such oriented nanofilms demonstrate stable relaxor characteristics with double the polarization intensity of unoriented films. Oriented relaxor polymers also uncover highly efficient cooperative polarization switching dynamics

which are both faster and more concentrated than those of their non-oriented counterparts. These findings provide key insights into relaxor behavior and establish a practical framework for the development of advanced low-field flexible electronics.
