Poly(vinylidene fluoride) PVDF bụ polymer ọkara kristal na-abụghị centrosymmetric nke na-egosipụta njirimara piezo-, pyro- na ferroelectric. Ọ bụ polymer kwụ ọtọ nke na-egosi dipoles eletriki na-adịgide adịgide na ntụziaka nke yinye molekul. Dipoles ndị a na-esite na ọdịiche dị na electronegativity dị n'etiti atọm nke hydrogen na fluorine ma e jiri ya tụnyere carbon. Dabere na ọnọdụ nhazi, PVDF na-egosipụta ọtụtụ usoro kristal dị iche iche (α,β,γ,δ). Usoro β nke PVDF bụ usoro nke na-egosipụta njirimara ferroelectric na piezoelectric kacha mma.
