Ua kapa ʻia ka hiki ʻana o kekahi mea i ke au uila. He ʻokoʻa ka conductivity o nā metala, ʻoi aku ka maikaʻi o ke kala, a ukali ʻia e ke keleawe a me ke gula. ʻO ka conduction solid-state e pili ana i ka neʻe lōʻihi o nā electrons a i ʻole nā ion i loko o kahi paʻa ma lalo o ka hana o kahi kahua uila, maʻamau ka mea lawe ukana, e like me: kahi mea lawe uila, nāna e hoʻokele i ka uila me nā mea lawe uila; Conductivity o ka mea hoʻokipa; a me nā conductors hui ʻia, nona nā electrons lawe a me nā ion. Eia kekahi, ʻaʻole i hoʻokumu ʻia kekahi mau mea uila e ka neʻe ʻana o ka mea lawe, akā ʻo ka polarization paʻa i hoʻokumu ʻia e ke kahua uila, e like me ka dielectric phenomena a me nā mea dielectric.
Ma keʻano laulā, hiki i nā metala, semiconductors, electrolytes, melt electrolytes a me kekahi mau metala ʻole ke hoʻokele uila. ʻO ka conductivity uila o nā mea non-electrolyte e pili ana i ka helu o nā electron manuahi i loko o kona ʻōpū waho atomic a me kona ʻano aniani. No ka laʻana, loaʻa i nā metala ka nui o nā electrons manuahi, a ʻo ka hapa nui o nā metala ʻaʻole maʻalahi ke alakaʻi i ka uila ma muli o kā lākou helu liʻiliʻi loa o nā electrons manuahi. Loaʻa i ka Diamond ka conductivity uila, e pili ana i ka ʻokoʻa o kona ʻano aniani. Hiki i nā Electrolytes ke hana i ka uila no ka mea ua hana ʻia nā anion i ka wā e hoʻoheheʻe ʻia ai ʻole hoʻoheheʻe ʻia nā pūhui ionic, a pēlā e hoʻokele ai i ka uila.
Ma ke ʻano he metala conductive ʻē aʻe ma mua o ke kālā, hoʻohana mau ʻia ke keleawe i nā kaula koʻikoʻi a me nā papa conductive. ʻO ke kiʻekiʻe o ka maʻemaʻe, ʻoi aku ka maikaʻi o ka conductivity.
Ma ke ʻano he 3D porous structure material i hana ʻia me ke keleawe ma ke ʻano he mea maka, ʻoi aku ka maikaʻi o ka ʻenehana keleawe a ʻoi aku ka kiʻekiʻe o ka ʻenehana hana, ʻoi aku ka kiʻekiʻe o ke keleawe, a ʻoi aku ka maikaʻi o ka conductivity uila e like me ia.
ʻO ka hoʻoili uila o ka pahu metala e pili ana i ka conductivity uila o ka metala nui. I nā manawa he nui, aia nā oxides me ka conductivity maikaʻi ʻole ma ka ʻili o ka metala kumu, a he nui nā conductors maikaʻi ʻole o ka uila i loko o ke ʻano porous o ka metala foamed, no laila ʻaʻole maikaʻi ka conductivity o ka metala foamed. o ka metala nui.
Ma ke kaulike o ka conductivity uila a me ka hoʻolālā porous 3D, ua kūkulu ʻia kekahi mau hiʻohiʻona e noʻonoʻo i nā mea ʻelua. I ka noi, ʻoiai ʻaʻole maikaʻi ka conductivity uila e like me nā kaula keleawe maʻemaʻe paʻa a me nā lau, ua hoʻokō piha ʻia nā pono o ka 3D porous structure. Ke hoʻohālikelike ʻia me nā mea keleawe maʻemaʻe ʻole, ʻoi aku ka maikaʻi o ka conductivity uila o ka pahu keleawe.
