I-carbon nanotubesyizinto ezimangalisayo.Bangaba namandla kunensimbi kuyilapho bebancane kunoboya bomuntu.

Ziphinde zizinze kakhulu, azisindi, futhi zinezakhiwo ezimangalisayo zikagesi, ezishisayo nezomshini.Ngenxa yalesi sizathu, babambe amandla okuthuthukiswa kwezinto eziningi ezithakazelisayo zesikhathi esizayo.

Bangase futhi babambe ukhiye wokwakha izinto kanye nezakhiwo zesikhathi esizayo, njengamakheshi emkhathini.

Lapha, sihlola ukuthi ziyini, zenziwa kanjani nokuthi yiziphi izinhlelo zokusebenza ezivame ukuba nazo.Lokhu akusho ukuthi kube umhlahlandlela ophelele futhi kuhloswe ukuthi kusetshenziswe kuphela njengokubuka konke okusheshayo.

Yini iziama-carbon nanotubesnezimpahla zabo?

Ama-nanotubes e-Carbon (ama-CNTs ngamafuphi), njengoba negama liphakamisa, ayizakhiwo eziyisilinda ezincane ezenziwe ngekhabhoni.Kodwa hhayi nje noma iyiphi ikhabhoni, i-CNT iqukethe amashidi agoqiwe ongqimba olulodwa lwe-carbon molecule ebizwa ngokuthi i-graphene.

Zivame ukuza ngezindlela ezimbili eziyinhloko:

1. Ama-nanotube ekhabhoni enodonga olulodwa(SWCNTs) - Lawa avame ukuba nobubanzi obungaphansi kuka-1 nm.

2. I-carbon nanotubes enezindonga eziningi(MWCNTs) - Lawa aqukethe ama-nanotube amaningana axhumene ngokujulile futhi avame ukuba namadiayamitha angafinyelela ngaphezu kuka-100 nm.

Kunoma ikuphi, ama-CNT angaba nobude obuguquguqukayo ukusuka phakathi kwama-micrometer ambalwa ukuya kumasentimitha.

Njengoba amashubhu akhiwe ngokukhethekile kusuka ku-graphene, abelana ngezinto eziningi ezithakazelisayo.Ama-CNT, isibonelo, ahlanganiswe namabhondi e-sp2 - lawa aqine ngokwedlulele ezingeni lamangqamuzana.

Ama-nanotubes e-Carbon nawo anomkhuba wokubopha izintambo ndawonye ngokusebenzisa amabutho e-van der Waals.Lokhu kubanikeza amandla aphezulu kanye nesisindo esincane.Futhi zivame ukuba izinto ezisebenza ngogesi kakhulu kanye ne-thermal-conductive.

"Izindonga zomuntu ngamunye ze-CNT zingaba zensimbi noma ze-semiconducting kuye ngokuthi i-lattice ibheke kuphi ngokuphathelene ne-tube axis, ebizwa ngokuthi i-chirality."

Ama-nanotubes ekhabhoni aphinde abe nezinye izinto ezishisayo ezishisayo nezemishini ezenza zithandeke ekwakheni izinto ezintsha.

Enzani ama-carbon nanotubes?

Njengoba sesibonile, ama-carbon nanotubes anezakhiwo ezingavamile kakhulu.Ngenxa yalokhu, ama-CNT anezinhlelo zokusebenza eziningi ezithakazelisayo nezihlukahlukene.

Eqinisweni, kusukela ngo-2013, ngokusho kweWikipedia nge-Science Direct, ukukhiqizwa kwe-carbon nanotube kudlula amathani ayizinkulungwane ezimbalwa ngonyaka.Lawa ma-nanotubes anezinhlelo eziningi zokusebenza, okuhlanganisa ukusetshenziswa ku:

• Izixazululo zokugcina amandla
• Ukumodela idivayisi
• Izakhiwo ezihlanganisiwe
• Izingxenye zezimoto, okuhlanganisa okungenzeka ukuthi usezimotweni ze-hydrogen fuel cell
• Izikebhe zemikhumbi
• Izimpahla zemidlalo
• Izihlungi zamanzi
• I-Thin-film electronics
• Izigqoko
• Ama-Actuator
• Electromagnetic shielding
• Izindwangu
• Izicelo ze-biomedical, okuhlanganisa ubunjiniyela bezicubu zethambo nemisipha, ukulethwa kwamakhemikhali, ama-biosensors nokuningi

Yini izimulti walled carbon nanotubes?

Njengoba sesibonile, ama-nanotube ekhabhoni anezindonga eziningi yilawo nanotubes enziwe ngama-nanotube amaningana axhumene ngokujulile.Zivame ukuba nama-diameter angafinyelela ngaphezu kwe-100 nm.

Angafinyelela ngaphezu kwamasentimitha ngobude futhi avame ukuba ne-aspect ratios ehluka phakathi kwezigidi ezingu-10 nezingu-10.

Ama-nanotube anezindonga eziningi angaqukatha phakathi kwezindonga eziqondile eziyisi-6 nezingu-25 noma ngaphezulu.

Ama-MWCNT anezakhiwo ezinhle kakhulu ezingase zisetshenziswe kwinani elikhulu lezinhlelo zokusebenza zentengiso.Lokhu kubandakanya:

• Ugesi: Ama-MWNT ahamba kahle kakhulu uma ehlanganiswe kahle nesakhiwo esiyinhlanganisela.Kumele kuqashelwe ukuthi udonga lwangaphandle lulodwa luqhuba, izindonga zangaphakathi azihlanganisi conductivity.
• I-Morphology: Ama-MWNT ane-aspect ratio ephezulu, enobude ngokuvamile obungaphezu kuka-100 ubukhulu, futhi kwezinye izimo buphakeme kakhulu.Ukusebenza kwawo kanye nokusetshenziswa kwawo akusekelwe nje ku-aspect ratio, kodwa futhi nasezingeni lokubanjwa kanye nokuqondisa kwamashubhu, okubuye kube umsebenzi wawo kokubili izinga kanye nobukhulu bokukhubazeka kumashubhu.
• Okungokomzimba: Angenasici, ngamanye, ama-MWNT anamandla amahle kakhulu okuqina futhi uma ehlanganiswe nenhlanganisela, njengezinhlanganisela ze-thermoplastic noma i-thermoset, angawandisa kakhulu amandla awo.
