Kev ua tau zoo ntawm Multi walled carbon nanotubes

Kev ua haujlwm hluav taws xob

Txhua cov pa roj carbon atom ntawm sp2 hybrid muaj ib qho hluav taws xob tsis sib haum xeeb rau pi orbital ntawm daim ntawv, uas muab cov pa roj carbon nanotubes zoo heev hluav taws xob conductivity.Qhov siab tshaj plaws tam sim no ntawm cov pa roj carbon nanotubes tuaj yeem ncav cuag 109Acm-2, uas yog 1000 npaug ntawm cov khoom siv tooj liab.Nws tuaj yeem siv los ua cov xaim me me, daim ntawv thov raug tam sim no siv los ua tus neeg sawv cev hauv cov roj teeb lithium-ion.Cov pa roj carbon nanotubes semiconducting muaj kev siv dav dua hauv cov khoom siv microelectronic.

Mechanical zog

sp2 hybrid CC σ daim ntawv cog lus yog ib qho ntawm cov khoom siv tshuaj muaj zog tshaj plaws uas paub tam sim no.Lub zog ntawm cov pa roj carbon nanotubes yog nyob rau hauv qhov kev txiav txim ntawm pua ​​pua ntawm GPa, thiab cov Young's modulus yog nyob rau hauv qhov kev txiav txim ntawm TPa, uas yog ntau dua li cov carbon fiber thiab lub cev armor.Siv fiber ntau thiab hlau.Nws xav tias yuav hloov cov pa roj carbon fiber ntau ua cov khoom siv zog tshiab.

Kev ua haujlwm thermal

Cov pa roj carbon nanotube thermal conduction system muaj qhov loj dua qhov nruab nrab phonon dawb txoj kev, thiab axial thermal conductivity yuav siab li 6600W / (m·K), uas yog ntau tshaj 3 npaug ntawm cov khoom siv thermal conductivity siab tshaj plaws ntawm chav tsev kub-pob zeb diamond. , uas yog nyob rau hauv qhov zoo tshaj plaws cov ntaub ntawv uas paub yog ib tug npaum li cas tshav kub dissipation khoom nyob rau hauv cov khoom siv hluav taws xob.

Nyob rau hauv xyoo tas los no, kev tshawb fawb ntawm carbon nanotubes tau pom tias daim ntawv thov kev cia siab nyob rau hauv nanoelectronic pab kiag li lawm, uas yog, los ntawm kev tsim cov khoom siv hluav taws xob thiab cov xov hlau raws li cov pa roj carbon nanotubes nrog ib tug loj ntawm kaum ntawm nanometers los yog txawm me me, lub realization ceev yog ceev npaum li cas. kev siv hluav taws xob tsawg dua li cov pa roj carbon nanotube integrated circuits ntawm tam sim no integrated circuits.

Tsis tas li MWCNT multi-walled carbon nanotubes tuaj yeem siv rau conductive, anti-static, catalyst carrier, thiab lwm yam.
