Li-nanotube tsa carbonke lintho tse makatsang.Li ka ba matla ho feta tšepe ha li ntse li le mosesaane ho feta moriri oa motho.

Li boetse li tsitsitse haholo, li bobebe, 'me li na le lisebelisoa tse makatsang tsa motlakase, mocheso le mochini.Ka lebaka lena, ba na le monyetla oa ho nts'etsapele lisebelisoa tse ngata tse khahlisang tsa nakong e tlang.

Ba ka 'na ba boela ba tšoara senotlolo sa ho aha thepa le meaho ea nako e tlang, joalo ka lilifi tsa sepaka-pakeng.

Mona, re hlahloba hore na ke eng, hore na li entsoe joang le hore na li na le lisebelisoa life.Sena ha se reretsoe ho ba tataiso e felletseng mme e reretsoe feela ho sebelisoa joalo ka kakaretso e potlakileng.

Ke engli-nanotube tsa carbonle thepa ea bona?

Li-nanotubes tsa carbon (CNTs ka bokhutšoane), joalo ka ha lebitso le bontša, ke metsotso ea cylindrical e entsoeng ka k'habone.Empa eseng feela k'habone, CNT's e na le maqephe a phuthoang a karolo e le 'ngoe ea limolek'hule tsa carbon tse bitsoang graphene.

Li atisa ho tla ka mefuta e 'meli e meholo:

1. Li-nanotube tsa carbon tse nang le lebota le le leng(SWCNTs) - Tsena li atisa ho ba le bophara bo ka tlase ho 1 nm.

2. Li-nanotube tsa carbon tse nang le marako a mangata(MWCNTs) - Tsena li na le li-nanotube tse 'maloa tse hokahaneng ka kotloloho mme li na le li-diameter tse ka fihlang ho feta 100 nm.

Boemong bofe kapa bofe, CNTs e ka ba le bolelele bo fapaneng ho tloha lipakeng tsa li-micrometer tse 'maloa ho isa ho lisentimitara.

Kaha li-tubes li hahiloe feela ho tsoa ho graphene, li arolelana lintho tse ngata tse khahlisang.Ka mohlala, li-CNTs li hokahane le li-bond tsa sp2 - tsena li matla haholo boemong ba limolek'hule.

Li-nanotubes tsa carbon le tsona li na le tšekamelo ea ho roala hammoho ka mabotho a van der Waals.Sena se ba fa matla a phahameng le boima bo tlase.Li boetse li na le lisebelisoa tse tsamaisang motlakase haholo le tse tsamaisang mocheso.

"Marako a motho ka mong a CNT a ka ba a tšepe kapa a semiconducting ho latela sebopeho sa lesela mabapi le axis ea tube, e bitsoang chirality."

Li-nanotubes tsa carbon li boetse li na le lisebelisoa tse ling tse hlollang tsa mocheso le mechine tse etsang hore li khahle bakeng sa ho etsa thepa e ncha.

Li-carbon nanotubes li etsa eng?

Joalokaha re se re bone, carbon nanotubes e na le lintho tse sa tloaelehang haholo.Ka lebaka lena, CNTs e na le lits'ebetso tse ngata tse khahlisang le tse fapaneng.

Ebile, ho tloha ka 2013, ho latela Wikipedia ka Science Direct, tlhahiso ea carbon nanotube e feta lithane tse likete tse 'maloa ka selemo.Li-nanotubes tsena li na le lits'ebetso tse ngata, ho kenyelletsa le ts'ebeliso ho:

• Litharollo tsa polokelo ea matla
• Moetso oa lisebelisoa
• Mehaho e kopantsoeng
• Likarolo tsa likoloi, ho kenyeletsoa tse ka bang teng ka har'a likoloi tsa hydrogen fuel cell
• Likarolo tsa likepe
• Thepa ea lipapali
• Lisefa tsa metsi
• Thin-filimi elektronike
• Liaparo
• Li-activators
• Tšireletso ea motlakase
• Lisebelisoa
• Lisebelisoa tsa biomedical, ho kenyelletsa boenjiniere ba lisele tsa masapo le mesifa, phepelo ea lik'hemik'hale, li-biosensors le tse ling

Ke engli-nanotube tsa carbon tse nang le marako a mangata?

Joalo ka ha re se re bone, li-nanotube tsa khabone tse ngata ke li-nanotubes tse entsoeng ka li-nanotube tse 'maloa tse hokahaneng.Li na le li-diameter tse ka fihlang ho feta 100 nm.

Li ka fihla bolelele ba lisenthimithara tse fetang lisenthimithara 'me li atisa ho ba le likarolo tse fapaneng tse pakeng tsa 10 le 10 milione.

Li-nanotubes tse nang le marako a mangata li ka ba le mabota a pakeng tsa 6 le 25 kapa ho feta.

Li-MWCNTs li na le thepa e ntle haholo e ka sebelisoang molemong oa lits'ebetso tse ngata tsa khoebo.Tsena li kenyelletsa:

• Motlakase: Li-MWNT li sebetsa haholo ha li kopantsoe hantle le sebopeho sa motsoako.Hoa lokela ho hlokomeloa hore lerako le ka ntle le le mong le tsamaisa, marako a ka hare ha a na thuso ho conductivity.
• Morphology: MWNTs e na le karo-karolelano e phahameng, ka bolelele ka makhetlo a fetang 100 bophara, 'me maemong a mang e phahame haholo.Ts'ebetso ea bona le ts'ebeliso ea bona ha lia itšetleha feela ka karo-karolelano ea likarolo, empa hape le ka tekanyo ea ho ts'oaroa le ho otloloha ha li-tubes, tseo ka lehlakoreng le leng e leng mosebetsi oa tekanyo le boholo ba likoli ka har'a li-tubes.
• 'Mele: E se nang sekoli, motho ka mong, li-MWNT li na le matla a matla a ho tsitsa mme ha li kopantsoe ka har'a motsoako, joalo ka metsoako ea thermoplastic kapa thermoset, li ka eketsa matla a eona haholo.
