Mu nkuru ibanziriza iyi twibanze kuri bumwe mu buryo bubiri butandukanye bwo kwivura muri capacitors za filime zikozwe mu byuma: kwivura mu buryo bworoshye, buzwi kandi nka high-voltage self-healing. Muri iyi nkuru tuzareba ubundi bwoko bwo kwivura mu buryo bworoshye, electrochemical self-healing, bukunze kwitwa low-voltage self-healing.

Kwivura hakoreshejwe amashanyarazi

Uko kwivura ubwako kugaragara akenshi muri capacitors za aluminiyumu zifite icyuma ku muvuduko muto. Uburyo bwo kwivura ubwako kugaragara ni ubu bukurikira: iyo hari inenge muri filime ya dielectric ya capacitor ya filime ifite icyuma, nyuma yo kongerwamo voltage kuri capacitor (nubwo voltage yaba iri hasi cyane), hazabaho umuvuduko munini w'amazi unyuze muri iyo nenge, ugaragazwa kuko ubukana bw'ubushyuhe bwa capacitor buri hasi cyane ugereranyije n'agaciro kagenwe mu miterere ya tekiniki. Birumvikana ko hari imigezi ya ionic ndetse n'imigezi ya elegitoroniki mu muvuduko w'amazi usohoka. Kubera ko ubwoko bwose bwa filime za organic bufite igipimo runaka cyo kwinjiza amazi (0.01% kugeza 0.4%) kandi kubera ko capacitors zishobora guhura n'ubushuhe mu gihe cyo gukora, kubika no gukoresha, igice kinini cy'umuvuduko wa ionic kizaba umuvuduko wa O2 na H-ion ukomoka ku mazi akoreshwa amashanyarazi. Iyo O2-ion imaze kugera kuri anode ya AL metalised, ihuzwa na AL igakora AL2O3, ikora buhoro buhoro urwego rwo gukingira AL2O3 uko igihe kigenda gihita kugira ngo ipfuke kandi ivange ikibazo, bityo yongera ubushobozi bwo kwirinda gukingira icyuma no kwikiza ubwacyo.

Biragaragara ko ingufu runaka zikenewe kugira ngo capacitor ya organic film capacitor ikoreshwe mu byuma irangire. Hari amasoko abiri y'ingufu, imwe ituruka ku ngufu naho indi ituruka ku buryo icyuma gishyuha n'uburyo gishyuha, ingufu zikenewe mu kwivura zikunze kwitwa ingufu zivura.

 
Kwivura ubwabyo ni cyo kintu cy'ingenzi cyane kuri capacitors za filime zikozwe mu byuma kandi inyungu zabyo ni nini. Ariko, hari ingaruka mbi zimwe na zimwe, nko kugabanuka buhoro buhoro k'ubushobozi bwa capacitors zikoreshwa. Niba ubushobozi bukora cyane, bizatuma ubushobozi bwazo n'ubudahangarwa bwazo bigabanuka cyane, ingoni yo gutakaza igabanuka cyane ndetse no gucika intege vuba kwa capacitors.

Niba ufite ubumenyi ku bindi bice by’imiterere y’ibyuma bikoresha icyuma bivura ubwabyo, turakwinginze ubiganireho.
