Tsananguro:
Poly(vinylidene fluoride) PVDF ipolymer isina centrosymmetric ine semi crystalline inoratidza piezo-, pyro- uye ferroelectric properties. Ipolymer ine linear inoratidza ma electric dipoles anogara aripo akatarisana negwara rema molecular chain. Ma dipoles aya anokonzerwa nemusiyano uripo pakati pema electronegativity pakati pemaatomu ehydrogen ne fluorine maererano nekabhoni. Zvichienderana nemamiriro ekugadzirisa, PVDF inoratidza ma crystalline phases akasiyana (α,β,γ,δ). β phase yePVDF ndiyo phase inoratidza ferroelectric ne piezoelectric properties dzakanakisa.

Kushandiswa
Poly (vinylidene fluoride) inodzivirira maasidhi akawanda uye maalkali asi inorwiswa nefuming sulfuric acid. Inonyungudika mu dimethylacetamide asi hainyungudike muzvinhu zvishoma zvinonyungudutsa polar. MaCopolymer akagadzirwa ne ethylene, tetrafluoroethylene, chlorotrifluoroethylene uye hexafluoroethylene. Yekupedzisira i elastomer inonzi Viton kana Fluorel.
Iyo homopolymer inoshandiswa sechivharo chisingapindi mishonga chesimbi, chezvivharo zvetangi, hose, uye pump impellors. Iyo elastomeric copolymer ine hexafluoroethylene kana yagadziriswa ne hexamethylenediamine inoshandiswa sechisimbiso, gasket, 0-ring, tube, coating uye lining.
Poly (vinylidene fluoride) inobatsira mukugadzira machira, firimu, jira rekusefa, machira emidziyo, machira ekusefa, zvikamu zvepombi, machira nemavharuvhu. Inoshandiswawo sezvinhu zve transducers mumidziyo yakaita semahedhifoni, maikorofoni uye ma sensor ezwi. Inokoshawo pakushandisa piezoelectric uye electrostrictive. Pamusoro pezvo, inobatsira pamitsetse yekuredza yemonofilament inotsiva monofilament yenylon. Inoshanda sechinobatanidza chinoshandiswa mukugadzira ma electrodes ecomposite emabhatiri e lithium ion. Inoshanda sechinodzivirira chepamusoro chewaya, nanomaterials uye ma sensor ekumanikidza. Inoshandiswa kugadzira mafirita anoshandiswa kugadzirira sampuro dze chromatography yemvura inoshanda zvakanyanya nedzimwe nzira dzekuongorora dzepamusoro.
Mapendi, firimu, jira rekusefa, machira emidziyo, mamembrane ekusefa, zvikamu zvepombi uye machira nemavharuvhu.
