I-Carbon Nanotubesizinto ezinhle kakhulu. Bangaba namandla kunensimbi ngenkathi bencipha kunezinwele zomuntu.

Futhi zizinzile, zingasindi, futhi zinezakhiwo ezimangalisayo zikagesi, ezishisayo nezemishini. Ngalesi sizathu, babamba amathuba okuthuthuka kwezinto eziningi ezijabulisayo zesikhathi esizayo.

Bangase futhi babambe ukhiye wokwakha izinto zokwakha nezakhiwo zekusasa, njengezindawo eziphakeme zesikhala.

Lapha, sihlola ukuthi bayini, ukuthi zenziwa kanjani nokuthi yiziphi izicelo abavame ukuba nazo. Lokhu akuhloselwe ukuba yigayidi eqeda amandla futhi kuhloswe ukuthi kusetshenziswe kuphela njengokubuka okusheshayo.

Yini iziI-Carbon Nanotubeskanye nezakhiwo zabo?

I-Carbon Nanotubes (CNTs Forfut), njengoba igama libonisa, yizakhiwo ze-cylindrical zenziwe ngekhabhoni. Kepha hhayi noma iyiphi ikhabhoni, ama-CNT aqukethe amashidi asongwe ngongqimba olulodwa lwama-molecule e-carbon abizwa nge-graphene.

Bajwayele ukuza ngezindlela ezimbili eziphambili:

1. I-Carbon Nanotubes eyodwa(SWCNTS) - Lokhu kuvame ukuba nobubanzi obungaphansi kwe-1 nm.

2. Ama-nanotubes amaningi e-carbon(MWCNTS) - Lokhu kuhlanganisa ama-nanotubes ahlukahlukene ahlanganiswe kakhulu futhi athambekele kumadayimitha angafinyelela ngaphezulu kwe-100 nm.

Kunoma yikuphi, ama-CNTs angaba nobude obuhlukahlukene phakathi kwama-micrometers amaningana kumasentimitha.

Njengoba amashubhu ayakhiwa kuphela kusuka ku-graphene, abelana ngezinto eziningi ezihehayo. Isibonelo, i-CNS, ihlanganiswe ngama-SP2 Bonds - Lawa aqine kakhulu ezingeni lamangqamuzana.

I-Carbon Nanotubes nayo inokuthambekela kwezintambo ndawonye ngeVan der Waals Forces. Lokhu kubanikeza amandla aphezulu nesisindo esiphansi. Futhi bavame ukuba yizinto zokwakha ezisebenza ngogesi kakhulu futhi eziphathekayo.

"Izindonga ze-CNT yomuntu ngamunye zingaba yinsimbi noma i-semiconducting ngokuya ngokuqagela kwe-lattice maqondana ne-axis ye-tube, ebizwa ngokuthi yiChirality."

I-Carbon Nanotubes nayo inezinye izakhiwo ezimangalisayo zokushisa nezemishini ezibenza bakhange ngokwakha izinto ezintsha.

Wenzani ama-carbon nanotubes?

Njengoba sesibonile, ama-carbon nanotubes anezakhiwo ezingejwayelekile. Ngenxa yalokhu, ama-CNTs anezicelo eziningi ezithokozisayo nezihlukahlukene.

Eqinisweni, kusukela ngo-2013, ngokusho kweWikipedia Via Scient Direct, Carbon Nanotube ukukhiqizwa kwadlula izinkulungwane zamathani ngonyaka. Lawa ama-nanotubes anezicelo eziningi, kufaka phakathi ukusetshenziswa ku:

• Izixazululo Zokugcina Amandla
• Modeling Specivius
• Izinhlaka eziyinhlanganisela
• Izingxenye zezimoto, kufaka phakathi okungaba khona kuma-hydrogen fuel cell cell
• Izikebhe zezikebhe
• Izimpahla zemidlalo
• Izihlungi zamanzi
• Ama-elekthronikhi wefilimu athambile
• Ukumboza
• ABUSTU
• Ukuvikelwa kwe-electromagnetic
• Izindwangu
• Izicelo ze-Biomedical, kufaka phakathi ubunjiniyela bezicubu zethambo kanye nemisipha, ukulethwa kwamakhemikhali, ama-bioses nokuningi

Yini iziAma-nanotubes amaningi e-carbon?

Njengoba sesibonile, ama-carbon nanotubes anhlobonhlobo ama-nanotubes awenziwa ama-nanotubes ahlukahlukene ahlanganiswe kakhulu. Bavame ukuba namadayimitha angafinyelela ngaphezulu kwe-100 nm.

Bangafinyelela ngaphezulu kwamasentimitha ubude futhi bathambekele ekubeni nezilinganiso ezingefani ezihlukahluka phakathi kwezigidi eziyi-10 nezingu-10.

Ama-nanotubes anezimbotshana eziningi angaqukatha phakathi kwezindonga ezi-6 no-25 noma ngaphezulu ezihlanganisiwe.

I-MWCNTS inezinye izakhiwo ezinhle ezingaxhashazwa ngenani elikhulu lezicelo zokuthengisa. Lokhu kufaka phakathi:

• Electrical: Ama-MWNTs aqhutshwa kakhulu lapho ahlanganiswe kahle esakhiweni esiyinhlanganisela. Kumele kwaziwe ukuthi udonga lwangaphandle luphela luqhuba, izindonga zangaphakathi azisebenzi ukuzokwenza.
• I-Morphology: Ama-MWNTs anesilinganiso esiphakeme kakhulu, ngobude ngokujwayelekile ngokuvamile ububanzi obukhulu, futhi ezimweni ezithile eziphakeme kakhulu. Ukusebenza kwabo kanye nesicelo sabo kusekelwe hhayi nje ku-Aspect Ratio, kepha futhi ngezinga lokubanjwa kanye nokuqondile kwamashubhu, okuwukusebenza kokubili degree kanye nobukhulu bobunzima kumashubhu.
• Okomzimba: Ukuphelelwa yithemba, umuntu ngamunye, ama-MWNTs anamandla amahle kakhulu ashubile futhi lapho ahlanganiswe kwinhlanganisela, njengezinhlanganisela ze-thermoplastic noma i-thermoset, zingakhulisa kakhulu amandla alo.
