Inkcazo:
I-Poly (vinylidene fluoride) i-PVDF yi-semi crystalline non-centrosymmetric polymer ebonisa iipropati ze-piezo-, pyro- kunye ne-ferroelectric. Yi-linear polymer ebonisa ii-dipoles zombane ezihlala zihleli zithe nkqo kwicala le-molecular chain. Ezi dipoles zivela kumahluko kwi-electronegativity phakathi kwee-athomu ze-hydrogen kunye ne-fluorine malunga ne-carbon. Ngokuxhomekeke kwiimeko zokucubungula, i-PVDF ibonisa ii-crystalline phases ezahlukeneyo (α,β,γ,δ). I-β phase ye-PVDF yi-phase ebonisa iipropati ze-ferroelectric kunye ne-piezoelectric ezilungileyo.

Ukusetyenziswa
I-Poly (vinylidene fluoride) ayixhathisi kwii-asidi ezininzi kunye nee-alkali kodwa ihlaselwa yi-fuming sulfuric acid. Iyanyibilika kwi-dimethylacetamide kodwa ayinyibiliki kwi-polar solvents ezincinci. Ii-Copolymers zenziwe nge-ethylene, i-tetrafluoroethylene, i-chlorotrifluoroethylene kunye ne-hexafluoroethylene. Le yokugqibela yi-elastomer ebizwa ngokuba yiViton okanye iFluorel.
I-homopolymer isetyenziswa njenge-coating enganyangekiyo kwiikhemikhali yentsimbi, kwii-linings zetanki, kwiipayipi, nakwii-impellors zepompo. I-copolymer ye-elastomeric ene-hexafluoroethylene xa inyangwa nge-hexamethylenediamine isetyenziswa njenge-seal, i-gasket, i-0-ring, ityhubhu, i-coating kunye ne-lining.
I-Poly (vinylidene fluoride) iluncedo kwiingubo, ifilimu, ilaphu lesihluzi, ii-instrument linings, ii-filtrate membranes, ii-pump parts, ii-linings kunye nee-valve. Ikwasetyenziswa njengezinto ze-transducers kwizixhobo ezifana nee-headphones, ii-microphone kunye ne-sonic detectors. Ikwabalulekile kwizicelo ze-piezoelectric kunye ne-electrostrictive. Ukongeza, iluncedo kwimigca yokuloba ye-monofilament ethatha indawo ye-nylon monofilament. Isebenza njenge-binder eqhelekileyo esetyenziswa ekuveliseni ii-electrodes ezidibeneyo zeebhetri ze-lithium ion. Isebenza njenge-insulator yomgangatho ophezulu yeengcingo, ii-nanomaterials kunye nee-pressure sensors. Isetyenziselwa ukwenza ii-filters ezisetyenziselwa ukulungiselela iisampulu ze-chromatography yolwelo olusebenza kakuhle kunye nezinye iindlela eziphambili zohlalutyo.
Iingubo, ifilimu, ilaphu lesihluzi, ii-linings zezixhobo, ii-filtrate membranes, iindawo zepompo kunye nee-linings kunye neevalvu.
