Poly(vinylidene fluoride) PVDF wani polymer ne mai siffar crystalline wanda ba shi da centrosymmetric wanda ke nuna halayen piezo-, pyro- da ferroelectric. Polymer ne mai layi wanda ke nuna dipoles na lantarki na dindindin a tsaye zuwa ga alkiblar sarkar kwayoyin halitta. Waɗannan dipoles suna faruwa ne sakamakon bambancin electronegativity tsakanin atom na hydrogen da fluorine dangane da carbon. Dangane da yanayin sarrafawa, PVDF yana nuna matakai daban-daban na crystalline (α,β,γ,δ). Matakin β na PVDF shine matakin da ke nuna mafi kyawun halayen ferroelectric da piezoelectric.
