Ka hana ana o Multiwalled carbon nanotubes

Hana uila

ʻO kēlā me kēia kalapona kalapona o ka sp2 hybrid he electron unpaired perpendicular to the pi orbital of the sheet, ka mea e hāʻawi ai i carbon nanotubes maikaʻi loa ka conductivity uila.Hiki ke hiki i ka 109Acm-2 ka nui loa o kēia manawa o nā nanotubes kalapona, ʻo ia ka 1000 mau manawa o ka conductivity o ke keleawe.Hiki ke hoʻohana ʻia ma ke ʻano he uea liʻiliʻi loa, ke hoʻohana ʻia nei ka noi maʻamau ma ke ʻano he conductive agent i nā pā lithium-ion.Loaʻa i ka semiconducting carbon nanotubes nā noi ākea ma ke kahua o nā mea microelectronic.

Nā waiwai mīkini

ʻO ka sp2 hybrid CC σ bond kekahi o nā mea paʻa kemika ikaika loa i ʻike ʻia i kēia manawa.ʻO ka ikaika o ka hāʻawi ʻana o nā nanotubes kalapona ma ke kauoha o nā haneli GPa, a ʻo ka modulus o ka Young ma ke kauoha o TPa, ʻoi aku ka kiʻekiʻe ma mua o ke kalapona kalapona a me ka pale kino.E hoʻohana i ka fiber a me ke kila.Manaʻo ʻia e hoʻololi i ka fiber carbon i mea ikaika hou.

Hana wela

Ke kalapona nanotube wela conduction nenoaiu i oi aku ka awelika phonon noa ala, a me ka axial thermal conductivity hiki e like kiʻekiʻe e like me 6600W / (m · K), i oi aku mamua o 3 manawa o ka mea me ka mea kiekie loa thermal conductivity ma ka lumi wela-diamond. , 'o ia ma ke 'ano 'O ka mea ki'eki'e loa i'ike'ia he mea ho'opau wela maika'i i nā lako uila.

I nā makahiki i hala iho nei, ua hōʻike ka noiʻi o carbon nanotubes i nā manaʻo noi i nā mea nanoelectronic, ʻo ia hoʻi, ma ke kūkulu ʻana i nā mea uila a me nā uea e pili ana i ka carbon nanotubes me ka nui o nā nanometers he ʻumi a i ʻole ka liʻiliʻi, ʻoi aku ka wikiwiki o ka ʻike. ʻoi aku ka liʻiliʻi o ka hoʻohana ʻana i ka mana ma mua o ka carbon nanotube integrated circuits o nā kaapuni hoʻohui i kēia manawa.

Hiki ke hoʻohana ʻia ka MWCNT multi-walled carbon nanotubes no conductive, anti-static, catalyst carrier, etc.
