Tlhaloso:
Poly(vinylidene fluoride) PVDF ke polymer e semi crystalline non-centrosymmetric e bonts'ang thepa ea piezo-, pyro- le ferroelectric. Ke polymer e otlolohileng e bonts'ang dipole tsa motlakase tse sa feleng tse otlolohileng ho ea ka tataiso ea ketane ea limolek'hule. Li-dipole tsena li bakoa ke phapang ea electronegativity pakeng tsa liathomo tsa haeterojene le fluorine mabapi le khabone. Ho latela maemo a ts'ebetso, PVDF e bonts'a mekhahlelo e fapaneng ea kristale (α,β,γ,δ). Karolo ea β ea PVDF ke karolo e bonts'ang thepa e ntle ka ho fetisisa ea ferroelectric le piezoelectric.

Tšebeliso
Poly (vinylidene fluoride) e hanela boholo ba li-acid le li-alkali empa e hlaseloa ke asiti ea sulfuric e nkhang hamonate. E qhibiliha ka har'a dimethylacetamide empa ha e qhibilihe ka har'a li-solvent tse fokolang tsa polar. Li-copolymer li hlahisitsoe ka ethylene, tetrafluoroethylene, chlorotrifluoroethylene le hexafluoroethylene. Ea morao ke elastomer e bitsoang Viton kapa Fluorel.
Homopolymer e sebediswa e le seaparo se thibelang dikhemikhale bakeng sa tshepe, bakeng sa di-lining tsa tanka, hose le di-impellor tsa pompo. Copolymer ya elastomeric e nang le hexafluoroethylene ha e phekolwa ka hexamethylenediamine e sebediswa e le seal, gasket, 0-ring, tube, coating le lining.
Poly (vinylidene fluoride) e thusa ho penteng, filiming, leselang la sefe, masela a disebediswa, masela a sefang, dikarolong tsa pompo, masela le di-valve. E boetse e sebediswa e le thepa bakeng sa di-transducer disebedisweng tse kang di-headphone, di-microphone le di-sonic detectors. E boetse e bohlokwa bakeng sa ditshebediso tsa piezoelectric le electrostrictive. Ho feta moo, e thusa bakeng sa mela ya ho tshwasa dihlapi ya monofilament e nkang sebaka sa monofilament ya nylon. E sebetsa e le binder e tloaelehileng e sebediswang tlhahisong ya di-electrode tse kopaneng bakeng sa dibetri tsa lithium ion. E sebetsa e le insulator ya maemo a hodimo bakeng sa dithapo, di-nanomaterials le di-sensor tsa kgatello. E sebediswa ho etsa di-filter tse sebediswang ho lokisa disampole bakeng sa chromatography ya metsi e sebetsang hantle le mekgwa e meng e tswetseng pele ya tlhahlobo.
Liaparo, filimi, lesela la sefe, masela a lisebelisoa, masela a sefang, likarolo tsa pompo le masela le li-valve.
