Ukukwazi kwento ukudlula umsinga wombane kubizwa ngokuba yi-conduction. Iintsimbi ezahlukeneyo zineendlela ezahlukeneyo zokuqhuba, ngokuqhelekileyo isilivere ineyona ndlela ihamba phambili, ilandelwa lubhedu kunye negolide. I-Solid-state conduction ibhekisela ekufudukeni komgama omde we-electron okanye i-ion kwindawo eqinileyo phantsi kwesenzo sentsimi yombane, ngokuqhelekileyo i-carrier carrier, njenge: i-electron conductor, eqhuba umbane ngokuyininzi kunye nabathwali be-electron; Ukuqhuba komkhosi; kunye nee-conductors ezixubeneyo, ezinazo zombini ii-electron ze-carrier kunye nee-ion. Ukongeza, ezinye izinto zombane azibangelwa kukufuduka komthwali, kodwa i-polarization eqinile ebangelwa yintsimi yombane, efana ne-dielectric phenomena kunye ne-dielectric materials.
Ngokubanzi, isinyithi, i-semiconductors, i-electrolytes, i-electrolyte enyibilikayo kunye nezinye ezingezona zentsimbi zinokuqhuba umbane. I-conductivity yombane yezinto ezingenayo i-electrolyte ixhomekeke kwinani lee-electron zamahhala kwi-shell yayo yangaphandle ye-athomu kunye nesakhiwo sayo se-crystal. Umzekelo, iintsimbi ziqulathe inani elikhulu leelektroni zasimahla, kwaye uninzi olungezizo iintsimbi alulula ukuqhuba umbane ngenxa yenani labo elincinci kakhulu leelektroni zasimahla. Idayimane ine-conductivity yombane, ehambelana nokwahlukana kwesakhiwo sayo se-crystal. I-Electrolytes iqhuba umbane ngenxa yokuba i-anion yenziwe xa i-ionic compounds ichitheka okanye inyibilika, kwaye ngaloo ndlela iqhuba umbane.
Njengentsimbi eqhubayo ngaphandle kwesilivere, ubhedu ludla ngokusetyenziswa kwiintambo ezibalulekileyo kunye neepleyiti zokuqhuba. Ukuphakama kobunyulu, ngcono i-conductivity.
Njengesixhobo se-3D esinemingxuma esenziwe ngobhedu njengento ekrwada, kokukhona umgangatho we-copper foam ungcono kwaye uphezulu ubuchwephesha bokwenza, kokukhona ubusulungekileyo bobhedu, kwaye kokukhona ukuhanjiswa kombane ngokufanelekileyo.
I-conductivity yombane ye-foam yensimbi ihambelana ne-conductivity yombane yentsimbi eninzi. Kwiimeko ezininzi, kukho iioksidi ezine-conductivity engalunganga kumphezulu wesiseko sesinyithi, kwaye kukho iziqhubi ezininzi ezimbi zombane kwisakhiwo esinemingxuma yesinyithi esinamagwebu, ngoko ke ukuqhutyelwa kwesinyithi esinamagwebu akulunganga ngolo hlobo. yentsimbi eninzi.
Kwibhalansi ye-conductivity yombane kunye ne-3D isakhiwo se-porous, iimodeli ezininzi ziye zaphuhliswa ezithatha ingqalelo zombini. Ekusetyenzisweni, nangona ukuqhutyelwa kombane akulunganga njengeentambo zobhedu ezicocekileyo kunye namaphepha, inzuzo ye-3D yesakhiwo se-porous isetyenziswe ngokupheleleyo. Xa kuthelekiswa nezinto zobhedu ezicocekileyo ezingaqinisiweyo, i-conductivity yombane ye-foam yobhedu ingcono.
