Cov Nanotubes yog cov tshiab polymer nanomaterials nrog kev ua tau zoo, zoo kawg thov kev ua tau zoo thiab ruaj khov.
Qhov tseem ceeb tshaj plaws cov qauv ntawm cov pa roj carbon nanotube Ciav tshuaj muab tshuaj txhuam yog tias nws yog tsim ntawm ib lossis ntau txheej ntawm graphite daim ntawv curled ib puag ncig tib lub chaw. Cov Nanotubes, xa mus rau raws li CNT ua lus Askiv, koom nrog tag nrho cov pa roj carbon system. Lawv yog micrometer-siized nyob rau hauv ntev thiab nanometer-loj hauv lub taub. Lawv yog cov xeeb ceem tshaj plaws ntawm ib-seem nanomaterials. Nyob rau macroscopic nplai, carbon nanotubes yog hmoov dub. On ntawm lub microscopic nplai, carbon nanotubes yog cov tshuaj carbon molecules muaj cov muaj cov hlau roj carbon monoxide. Txhua txheej ntawm cov hlab roj carbon yog ua los ntawm cov qauv roj densely pw hauv graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtseg qauv ntawm graphene, thiab cov khaubncaws sab nraud povtsuaj Txawm hais tias tus qauv ntawm cov pa roj carbon nanotubes zoo ib yam li cov ntaub ntawv polymer, nws cov qauv yog qhov ruaj khov ntau dua li cov ntaub ntawv polymer. Nws yog cov khoom siv nrog lub siab tshaj plaws melting point paub kom deb li deb.
Cov Nanotube Conde muab muab faib ua ntau hom raws li cov yam ntxwv sib txawv. Los ntawm kev pom kev lag luam, nws feem ntau yog feem ntau ua raws li cov khaubncaws sab nraud povtseg thiab kev tshaj lij ntawm lub raj raj raj. Raws li tus naj npawb ntawm cov khaubncawsbones ntawm cov pa roj carbon, carbon nanotubes tuaj yeem faib ua ib leeg-walled carbon nanotubes thiab ntau phab ntsa carbon nanotubes; Hais txog conductivity, carbon nanotubes tuaj yeem yog xim hlau lossis semiconducting, thiab txawm ntau qhov chaw ntawm cov pa roj carbon nanotube tuaj yeem qhia sib txawv. Yog li ntawd, raws li qhov sib txawv hauv kev ua haujlwm zoo, nws tuaj yeem faib ua hlau carbon nanotubes thiab semiconduces carbon nanotubes.
Cov qauv tshwj xeeb thiab cov tshuaj phem ntawm cov pa roj carbon nanotube cerease muab nws tus kheej tshuab, thermal thiab tshuaj lom neeg siv hauv ntau thaj teb.
Cov Khoom Siv Neeg Kho Tshuab
1) Lub zog zoo tshaj plaws: Cov kev sib txuas lus sib txuas txuas cov pa roj carbon atoms hauv cov pa roj carbon nanotubes yog cov neeg siv tshuaj uas ruaj khov tshaj plaws hauv xwm. Cov Nanotubes muaj lub zog tensile tsis tshua muaj zog thiab elastic maculus. Nyob rau tib lub sijhawm, qhov ntom ntawm cov pa roj carbon nanotubes tsuas yog 1\/6 ntawm cov hlau, ua rau nws lub zog tshaj plaws uas tuaj yeem npaj tau tam sim no.
2) Muaj zog hloov tau: Cov Nanotubes muaj zog yog muaj zog tab sis tsis nkig. Thaum khoov roj carbon nanotubes lossis thov siab rau lawv axusially, txawm tias lub zog sab nraud tshaj li lub zog ntawm Euler yuav tsis tawg, tab sis yuav ua thawj zaug khoov ntawm lub kaum sab xis loj. Thaum lub zog sab nraud yog tso tawm, cov pa roj carbon nanotubes rov qab rau lawv cov qauv qub.
Cov Khoom Siv Hluav Taws Xob
3) Kev Ua Haujlwm Zoo: Tus qauv ntawm cov pa roj carbon nanotubes yog tib yam li cov qauv qauv ntawm graphite, thiab muaj kev ua haujlwm zoo. Cov kev tawm tsam ntawm cov pa roj carbon nanotubes yog ywj siab ntawm lawv qhov ntev thiab lub taub. Thaum cov tshuab hluav taws xob dhau los ntawm cov nanotubes, lawv tsis tsim cov cua sov kom ua kom sov cov pa roj carbon nanotubes. Cov khoom xa hluav taws xob hauv carbon nanotubes yog zoo li cov kev xa tawm ntawm lub teeb ntsuas ntawm cov cim fiber ntau. Lub zog poob yog me me, thiab nws yog tus neeg coj tus thawj coj zoo.
4)) Cov khoom siv hluav taws xob zoo heev: Cov Nanotubes tau muaj siab heev thermal conductivity, uas yog ob zaug uas muaj pob zeb diamond ntawm chav tsev. Nws yog qhov zoo tshaj plaws uas paub thermal ua cov khoom siv. Tsis tas li ntawd, kev sib pauv cua sov ntawm cov pa roj carbon nanotubes hauv cov kev taw qhia axial yog siab heev, thaum lub tshav kub sib pauv hauv cov kev taw qhia radial yog tsawg. Los ntawm kev taw qhia tsim nyog, cov pa roj carbon nanotubes tuaj yeem ua ke rau hauv anisottropic thermal cov ntaub ntawv conductive cov ntaub ntawv.
5) Cov khoom lag luam hydrogen zoo: cov pa roj carbon nanotubes muaj qhov chaw tshwj xeeb thaj tsam thiab muaj kev cia siab hydrogen cia tom qab kev kho.
6) Zoo heev lithium cov khoom lag luam: hollow raj kab noj hniav ntawm cov khaubncaws sab nraud povtseg, cov khoob ntawm cov raj ntawm cov chaw tso tawm thiab thauj mus los raws li Lithium ions.
7) Tshuaj Muaj Zog: Cov Nanotubes yog cov nanotubes yog tshuaj ruaj khov thiab muaj kua qaub thiab alkali tsis kam. Ntxiv cov pa roj carbon nanotubes rau cov pa roj polymer tuaj yeem txhim kho cov kua qaub thiab oxidation tsis kam ntawm cov khoom nws tus kheej.
