IMITERERE:
Ibisobanuro:
Poly (vinylidene fluoride) PVDF ni polymeri idasanisha neza ifite imiterere ya semi crystalline, igaragaza imiterere ya piezo-, pyro- na ferroelectric. Ni polymeri isanzwe igaragaza dipoli z'amashanyarazi zihoraho zigororotse ku cyerekezo cy'uruhererekane rw'ibintu. Izi dipoli zikomoka ku itandukaniro riri hagati ya atome za hydrogen na fluorine ugereranyije na karuboni. Bitewe n'imiterere y'itunganywa, PVDF igaragaza ibyiciro bitandukanye bya crystalline (α,β,γ,δ). Icyiciro cya β cya PVDF ni cyo kigero kigaragaza imiterere myiza ya ferroelectric na piezoelectric.

Imikoreshereze
Poly (vinylidene fluoride) irwanya aside nyinshi na alkali ariko yibasirwa na aside sulfure ifumba. Irashonga muri dimethylacetamide ariko ntishonga mu bintu bike bishongesha ikirere. Copolymers zakozwe na ethylene, tetrafluoroethylene, chlorotrifluoroethylene na hexafluoroethylene. Iyi ya nyuma ni elastomer yitwa Viton cyangwa Fluorel.
Homopolymer ikoreshwa nk'igitambaro kidakoresha imiti mu byuma, mu byuma bifatanye n'ibigega, imiyoboro y'amazi n'imashini zikoresha pompe. Copolymer ya elastomeric hamwe na hexafluoroethylene iyo ivuwe na hexamethylenediamine ikoreshwa nk'igipfundikizo, gasket, 0-ring, tube, coating na lining.
Poly (vinylidene fluoride) ni ingirakamaro mu gutwikira, filime, igitambaro cyo kuyungurura, utwenda tw'ibikoresho, utwenda two kuyungurura, ibice bya pompe, utwenda two kuyungurura na valve. Ikoreshwa kandi nk'ibikoresho bya transducers mu bikoresho nka ecouteurs, mikoro na sonic detectors. Ni ingenzi kandi mu gukoresha piezoelectric na electrostrictive. Byongeye kandi, ni ingirakamaro ku migozi ya monofilament isimbuza monofilament ya nylon. Ikora nk'icyuma gisanzwe gikoreshwa mu gukora electrodes za composite kuri bateri za lithium ion. Ikora nk'icyuma gikingira cy'urwego rwo hejuru ku nsinga, nanomaterials na sensors z'umuvuduko. Ikoreshwa mu gukora filters zikoreshwa mu gutegura ingero za chromatography y'amazi ifite imikorere myiza n'ubundi buryo bugezweho bwo gusesengura.
Imyambaro, firime, igitambaro cyo kuyungurura, imitako y'ibikoresho, utwenda two kuyungurura, ibice bya pompe n'imitako n'uturindantoki.
