Incazelo:
I-Poly (vinylidene fluoride) i-PVDF iyi-polymer engeyona i-centrosymmetric e-semi crystalline ekhombisa izakhiwo ze-piezo-, pyro- kanye ne-ferroelectric. Iyi-polymer eqondile ekhombisa ama-dipole kagesi ahlala njalo aqonde ngqo ohlangothini lwe-molecule chain. Lawa ma-dipole avela emehluko we-electronegativity phakathi kwama-athomu e-hydrogen kanye ne-fluorine maqondana ne-carbon. Kuye ngezimo zokucubungula, i-PVDF ibonisa izigaba eziningana ezahlukene ze-crystalline (α,β,γ,δ). Isigaba se-β se-PVDF yisigaba esibonisa izakhiwo ze-ferroelectric kanye ne-piezoelectric ezinhle kakhulu.

Ukusetshenziswa
I-Poly (vinylidene fluoride) imelana nama-acid amaningi nama-alkali kodwa ihlaselwa yi-fuming sulfuric acid. Iyancibilika ku-dimethylacetamide kodwa ayincibiliki kuma-solvents amancane. Ama-Copolymer akhiqizwe nge-ethylene, i-tetrafluoroethylene, i-chlorotrifluoroethylene kanye ne-hexafluoroethylene. Lokhu kokugcina kuyi-elastomer ebizwa ngokuthi i-Viton noma i-Fluorel.
I-homopolymer isetshenziswa njengengubo engamelani namakhemikhali yensimbi, yezintambo zamathangi, ipayipi, kanye nama-impellor ephampu. I-copolymer ye-elastomeric ene-hexafluoroethylene uma ilashwa nge-hexamethylenediamine isetshenziswa njenge-seal, i-gasket, i-0-ring, ipayipi, i-coating kanye ne-lining.
I-Poly (vinylidene fluoride) iwusizo ekumbozweni, ifilimu, indwangu yokuhlunga, izintambo zezinsimbi, izinhlaka zokuhlunga, izingxenye zephampu, izintambo kanye nama-valve. Iphinde isetshenziswe njengento yokwenziwa kwama-transducer kumadivayisi anjenge-headphone, ama-microphone kanye ne-sonic detectors. Ibalulekile futhi ekusetshenzisweni kwe-piezoelectric kanye ne-electrostrictive. Ngaphezu kwalokho, iwusizo emigqeni yokudoba ye-monofilament ethatha indawo ye-nylon monofilament. Isebenza njenge-binder ejwayelekile esetshenziswa ekukhiqizweni kwama-electrode ahlanganisiwe amabhethri e-lithium ion. Isebenza njengesivikelo sezinga eliphezulu sezintambo, izinto ezisetshenziswa kakhulu kanye nezinzwa zokucindezela. Isetshenziselwa ukwenza izihlungi ezisetshenziselwa ukulungiselela amasampula e-chromatography yoketshezi esebenza kahle kakhulu kanye namanye amasu okuhlaziya athuthukile.
Izimbozo, ifilimu, indwangu yokuhlunga, izindwangu zensimbi, izindwangu zokuhlunga, izingxenye zephampu kanye nezindwangu kanye namavalvu.
