Direct evidence for electrostriction‐enhanced piezoelectricity in poly(vinylidene fluoride‐co‐trifluoroethylene) random copolymers

Responsive Materials, Volume 4, Issue 2, May 2026.
Direct experimental evidence for electrostriction‐enhanced piezoelectricity is obtained for a quenched‐stretched‐annealed‐poled P(VDF‐TrFE) 52/48 mol.% random copolymer using time‐resolved small‐angle X‐ray scattering and wide‐angle X‐ray diffraction. Upon stretching up to 6% strain, the crystallinity (xc) increases 10% at the expense of the contents ...
