Njengommeleli kakhulu we-nanomatale enobukhulu,I-Carbon Nanotubes eyodwa(Swcnts) inezakhiwo eziningi ezinhle kakhulu zomzimba nezamakhemikhali. Ngokucwaninga okuqhubekayo okujulile kokuyisisekelo nokusetshenziswa kwe-carbon nanotubes eyodwa ebingelwa yi-carbon, akhombisa amathuba okusebenza abanzi ezinkambeni eziningi, kufaka phakathi izithasiselo ze-nano, amafilimu ezinto ezibonakalayo, amafilimu we-catalyst, amafilimu we-bio-nano, njll.

Izakhiwo zemishini ze-Carbon Nanotubes eyodwa

Ama-athomu e-carbon e-carbon nanotubes eyodwa ahlanganiswe nezibopho eziqinile ze-CC COOLEND. Kucatshangelwa kusuka esakhiweni esinamandla aphezulu angenzi lutho, uBremsstrahleng kanye ne-elastic modulus. Abaphenyi balinganisa imvamisa yokudlidliza yokuphela kwamahhala kwama-CNTs ama-CNTs futhi bathola ukuthi i-modulus ye-carbon nanotubes ingafinyelela i-1TPA, ecishe ilingane ne-modulus yedayimane, ecishe ibe ngamahlandla ama-5. Ama-SWCNTs anamandla aphezulu aphezulu ambi, cishe izikhathi eziyi-100 zensimbi; Uhlobo olunwebekile lwe-carbon nanotubes eyodwa-olubi olulodwa lungama-5%, kuze kufike ku-12%, okungama-60 amahlandla angama-60 ensimbi. I-CNT inobunzima obuhle kakhulu nokugunda.

I-Carbon Nanotubes edonswe ngodonga olulodwa yikuqinisa kahle kwezinto ezihlanganisiwe, ezingadlulisela izakhiwo zazo ezinhle kakhulu zemishini ezintweni ezihlanganisiwe, ngakho-ke ukuthi izinto ezihlanganisiwe zibonisa amandla, ukuqina, ukuqina kokukhathala ukuthi abanazo ekuqaleni. Ngokuya ngamaNanoprobes, i-carbon nanotubes ingasetshenziswa ukwenza amathiphu we-scan scan ngokuskena ngokulungiswa okuphezulu nokujula okuphezulu kokutholwa.

Izici zikagesi ze-Carbon Nanotubes eyodwa

Isakhiwo se-tusher tubular solodwa se-carbon nanotubes eyodwa edonswayo sinquma izakhiwo zayo ezihlukile nezihle kakhulu zikagesi. Ucwaningo lwe-theoretical lukhombisile ukuthi ngenxa yokuhamba nge-ballistic kwama-elektroni ama-nanotubes, umthamo wamanje wokuthwala kuwo uphakeme njengo-109A / CM2, okuphezulu kwethusi ngokusebenza okuhle. Ububanzi be-carbon nanotube eyodwa ebiyelwe ngodongeni bumayelana ne-2NM, kanye nokunyakaza kwama-elektroni kunayo i-quantum yokuziphatha. Ethintwa yi-Quantum Physics, njengoba ububanzi kanye nemodi ye-SWCNT Shintsha, igebe lamandla weqembu le-valence futhi i-conduction band ingashintshwa kusuka ku-zero kuya ku-1 Kuze kube manje, ayikho enye into etholakele ukuthi ifana ne-carbon nanotubes eyodwa edonswa yi-carbon nayo ingalungisa igebe lamandla ngokushintsha ukuguqulwa kwama-athomu.

I-Carbon Nanotubes, efana ne-graphite nedayimane, bangabaqhubi abahle kakhulu abashisayo. Njengokuqhutshwa kwabo ngogesi, ama-nanotubes e-carbon nawo anokuphakelayo okuhle kwe-axial axial futhi akulungile izinto ezisebenzayo ezishisayo. Izibalo ze-Theoretical zibonisa ukuthi uhlelo lokushisa lokushisa lwe-carbon nanotube (CNT) lunendlela enkulu yamahhala yama-purons, izingxoxo zalo zidluliselwe kahle kanye nepayipi, futhi ukuvumelanisa kwalo okuxakekile kumayelana ne-6600W / m • K noma ngaphezulu, okufana nokuvuselelwa kwe-thermal of lingle-ungqimba graphene. Abaphenyi balinganisa ukuthi izinga lokushisa lekamelo elishisayo le-carbon nanotube elilodwa elibingelwe yi-carbon nanotube (SWCNT) lisondele ku-3500W / m Yize ukusebenza kokushisa kokushisa kwe-carbon nanotubes eqondisweni ze-axial kuphezulu kakhulu, ukusebenza kwawo kokushisa okuphezulu kuncishiswe yi-geometric ephansi, futhi ukunwebeka kwawo kunqunyelwe ku-zero, ngakho-ke i-carbon nanotubes ilinganiselwe kwinqwaba, ukushisa kwawo kuhlanganiswe ku-carbon nanotube kuya kwenye.

Ukuvuselelwa okungcono kakhulu kwe-carbon nanotubes okukodwa kwe-carbon nanotubes (SWCNTS) kubhekwa njengento enhle kakhulu yendawo yokuxhumana yezindawo zokuxhumana ezilandelayo, ezingabenza babe yi-ejenti yokuvuselela ama-radiators wekhompyutha we-CPU chip esikhathi esizayo. I-radiator ye-carbon nanotube CPU, indawo yakhe yokuxhumana ne-CPU yenziwe ngokuphelele nge-carbon nanotubes, inokuphamba okushisa amahlandla ama-5 asetshenziswa izinsiza zamathusi ezijwayelekile. Ngasikhathi sinye, ama-carbon nanotubes angawodwa anamathemba wohlelo lokusebenza ezintweni eziphakeme ze-armickivity composite izinto futhi zingasetshenziswa ezingxenyeni ezihlukile zokushisa okuphezulu njengezinjini namarokhethi.

Izakhiwo ze-Optical ze-Carbon Nanotubes eyodwa

Isakhiwo esiyingqayizivele se-carbon nanotubes eyodwa - sidale izakhiwo zayo ezihlukile ze-Optical. I-Raman Spectroscopy, i-fluorescence spectroscopy kanye ne-ultraviolet-ebonakalayo-ebonakalayo-esondela ebonakalayo ye-infraredroscopy isetshenziswe kabanzi ekufundweni kwezakhiwo zayo ezibonakalayo. I-Raman Spectroscopy iyithuluzi elisetshenziswa kakhulu lokutholwa kwe-carbon nanotubes eyodwa. Imodi yokudlidliza eyindinganiso ye-Carbon Nanotubes ye-Vibration ye-Vibving engabodwa (i-RBM) ivela cishe ngo-200nm. I-RBM ingasetshenziselwa ukunquma ukucaciswa kwe-microsbon nanotubes futhi inqume ukuthi isampula liqukethe i-carbon nanotubes eyodwa ebingelwa yikhabhoni.

Izici Zobuthene ze-Carbon Nanotubes eyodwa

I-Carbon Nanotubes inezindawo eziyingqayizivele zezibuthe, ezi-anisotropic ne-diamagnetic, futhi zingasetshenziswa njengezinto ezithambile ze-ferromagnetic. Amanye ama-carbon nanotubes anodonga olubiwodwa anezakhiwo ezithile nawo ane-superconductivity futhi angasetshenziswa njengezintambo ezinhle kakhulu.

Ukusebenza Kwesitokwe segesi se-carbon nanotubes eyodwa

Isakhiwo esisodwa se-tubular kanye nobude obukhulu bobubanzi be-carbon nanotubes ye-carbon-wally eyodwa benza umthambo weshubhu ongenamsebenzi ube nomphumela oqinile we-capillary, ukuze inezinhlaka ezihlukile ze-adsorption, ukugcinwa kwegesi kanye nezimpawu zokungena. Ngokusho kwemibiko ekhona yocwaningo, ama-carbon nanotubes angawodwa we-carbon anezinto zokwakha ama-adsolption anomthamo omkhulu we-hydrogen wesitoreji, odlula ezinye izinto zokugcina ze-hydrogen, futhi zizosiza ukukhuthaza ukuthuthukiswa kwamangqamuzana kaphethiloli we-hydrogen.

Umsebenzi we-catalytic we-carbon nanotubes eyodwa

I-Carbon Nanotubes eyodwa edonswe yi-carbon inokuqhutshwa okuhle kakhulu ngogesi, ukuqina okuphezulu kwamakhemikhali kanye nendawo enkulu engaphezulu komhlaba (SSA). Zingasetshenziswa njengama-catalysts noma abathwali be-catalyst, futhi babe nomsebenzi ophakeme we-catalytic. Akunandaba ne-heterogeneous catalysis yendabuko, noma nge-elektrocacisisis kanye ne-photocatalsis, i-carbon nanotubes eyodwa ebingelwe yi-carbon ibonise amandla amakhulu wohlelo lokusebenza.

UGuangzhou Hongwewu uhlinzeka ngekhwalithi ephezulu ye-carbon nanotubes ebiwolwayo ebiyelwe ngodonga elinobude obuhlukile, ubumsulwa (91- 99%), izinhlobo ezisebenzayo. Futhi ukuhlakazeka kungenziwa ngezifiso.
