Nanotubes kalaponahe mau mea kupanaha.Hiki iā lākou ke ʻoi aku ka ikaika ma mua o ke kila a ʻoi aku ka lahilahi ma mua o ka lauoho kanaka.

Paʻa loa lākou, māmā, a loaʻa iā lākou nā waiwai uila, wela a me nā mīkini.No kēia kumu, paʻa lākou i ka hiki ke hoʻomohala i nā mea hoihoi e hiki mai ana.

Hiki iā lākou ke paʻa i ke kī no ke kūkulu ʻana i nā mea a me nā hale o ka wā e hiki mai ana, e like me nā mea hoʻokiʻekiʻe ākea.

Ma ʻaneʻi, ʻimi mākou i ke ʻano o ia mau mea, pehea i hana ʻia ai a me nā noi e loaʻa iā lākou.ʻAʻole kēia i manaʻo ʻia he alakaʻi hoʻopau a manaʻo wale ʻia e hoʻohana ʻia ma ke ʻano he ʻike wikiwiki.

He aha nācarbon nanotubesa me ko lakou mau waiwai?

ʻO nā nanotubes kalapona (CNTs no ka pōkole), e like me ka manaʻo o ka inoa, he mau hana cylindrical minuke i hana ʻia mai ke kalapona.ʻAʻole naʻe he kalapona wale nō, ʻo ka CNT he mau pepa i ʻōwili ʻia o hoʻokahi papa o nā molekala kalapona i kapa ʻia he graphene.

Hele mai lākou i ʻelua mau ʻano nui:

1. Nā nanotubes kalapona pā hoʻokahi(SWCNTs) - Loaʻa kēia mau mea i ke anawaena o lalo o 1 nm.

2. Nā nanotubes kalapona pā lehulehu(MWCNTs) - Aia kēia mau mea he mau nanotubes concentrically-interlinked a loaʻa i nā anawaena hiki ke piʻi ma mua o 100 nm.

I kēlā me kēia hihia, hiki i nā CNT ke loaʻa nā lōʻihi like ʻole mai waena o kekahi mau micrometers a hiki i ke kenimika.

No ka mea, kūkulu wale ʻia nā paipu mai ka graphene, kaʻana like lākou i kāna mau waiwai hoihoi.ʻO nā CNT, no ka laʻana, ua hoʻopaʻa ʻia me nā mea paʻa sp2 - ikaika loa kēia ma ka pae molekala.

Hiki nō hoʻi i nā nanotubes kalapona ke kaula pū me nā pūʻali van der Waals.Hāʻawi kēia iā lākou i ka ikaika kiʻekiʻe a me ke kaumaha haʻahaʻa.Hoʻohana nui lākou i ka uila-conductive a me ka thermally-conductive mea.

"Hiki i nā pā CNT pākahi ke metala a semiconducting paha ma muli o ke ʻano o ka lattice e pili ana i ke axis tube, i kapa ʻia ʻo chirality."

Loaʻa iā Carbon nanotubes kekahi mau mea wela a me nā mea mechanical e hoʻonanea ai no ka hoʻomohala ʻana i nā mea hou.

He aha ka hana a nā nanotubes kalapona?

E like me kā mākou i ʻike mua ai, loaʻa i nā nanotubes carbon kekahi mau mea maʻamau.Ma muli o kēia, he nui nā noi hoihoi a me nā ʻano like ʻole o nā CNT.

ʻO ka ʻoiaʻiʻo, e like me 2013, e like me Wikipedia ma o Science Direct, ua ʻoi aku ka nui o ka hana kalapona nanotube ma mua o nā tausani mau tone i kēlā me kēia makahiki.He nui nā noi o kēia mau nanotubes, me ka hoʻohana ʻana i:

• Nā hāʻina mālama mālama ikehu
• Hoʻohālike mea hoʻohālike
• Nā hale hui
• ʻO nā ʻāpana kaʻa, me nā kaʻa kaʻa hydrogen wahie
• Nā ʻili waʻa
• Nā mea pāʻani
• Nā kānana wai
• Mea uila kiʻiʻoniʻoni lahilahi
• Nā uhi
• Nā mea hoʻokele
• Palena electromagnetic
• Nā lole lole
• Nā noi biomedical, me ka ʻenekinia kiko o ka iwi a me ka ʻiʻo, ka lawe ʻana i nā kemika, nā biosensors a me nā mea hou aku

He aha nānā nanotubes kalapona pā lehulehu?

E like me kā mākou i ʻike mua ai, ʻo nā nanotubes carbon multiwalled nā nanotubes i hana ʻia mai kekahi mau nanotubes concentrically interlinked.Loaʻa iā lākou nā anawaena hiki ke piʻi ma mua o 100 nm.

Hiki iā lākou ke piʻi aku ma mua o ke kenimika ka lōʻihi a loaʻa iā lākou nā hiʻohiʻona like ʻole ma waena o 10 a 10 miliona.

Hiki ke komo i waena o 6 a me 25 mau paia concentric a ʻoi aʻe paha nā nanotubes pā nui.

Loaʻa i nā MWCNT kekahi mau waiwai maikaʻi loa i hiki ke hoʻohana ʻia i ka nui o nā noi kalepa.Aia kēia mau mea:

• Uila: ʻO nā MWNT ka mea hoʻokele maikaʻi ke hoʻohui pono ʻia i loko o kahi ʻano hui.Pono e hoʻomaopopo ʻia ʻo ka pā o waho wale nō ke alakaʻi, ʻaʻole pono nā paia o loko i ka conductivity.
• Morphology: Loaʻa i nā MWNT kahi lākiō hiʻohiʻona kiʻekiʻe, me nā lōʻihi maʻamau ma mua o 100 mau manawa o ke anawaena, a i kekahi mau hihia ʻoi aku ka kiʻekiʻe.ʻAʻole i hoʻokumu ʻia kā lākou hana a me ka hoʻohana ʻana i ka lākiō hiʻohiʻona, akā ma ke ʻano o ka entanglement a me ka pololei o nā paipu, ʻo ia hoʻi ka hana o ka degere a me ka nui o nā hemahema i loko o nā paipu.
• Ke Kino: Loaʻa i ka MWNT ka ikaika tensile maikaʻi loa, ʻaʻohe kīnā, hoʻokahi, a ke hoʻohui ʻia i loko o ka composite, e like me ka thermoplastic a i ʻole ka thermoset compound, hiki ke hoʻonui nui i kona ikaika.
