Cov Nanotubes, qhov no zoo tshaj plaws nanomaterial, tau nyiam ntau dua txij li thaum nws tshwm sim vim nws lub cev thiab tshuaj lom neeg tshwj xeeb. Ntawm lawv, hluav taws xob cuam tshuam ntawm cov pa roj carbon nanotubes tau ua tshwj xeeb yog ua rau muaj kev txaus siab ntau ntawm cov kws tshawb fawb ntawm ntau. Yog li, cov pa roj carbon nanotubes yeej muaj hluav taws xob conductivity? Cov lus teb yog muaj.
Txhawm rau kom nkag siab txog cov qauv theem pib ntawm cov pa roj carbon nanotubes. Nws yog lub tubular qauv muaj cov carbon atoms teem rau hauv ib txoj kev. Tus qauv no xaus carbon nanotubes nrog ntau yam khoom siv. Ntawm lawv, qhov tseem ceeb tshaj plaws yog nws qhov hluav taws xob conductivity. Vim tias cov pa roj carbon nanotubes tau txuas los ntawm kev sib txuas lus, yog li cov pa roj carbon nanotubes, yog li preceploing carbon nanotubes nrog hluav taws xob zoo.
Tsis tas li ntawd, cov hluav taws xob cuam tshuam ntawm cov pa roj carbon nanotubes yog ze rau lawv txoj kab uas hla thiab chairality. Kev tshawb fawb tau pom tias thaum lub cheeb ntawm carbon nanotubes yog me me, lawv cov hluav taws xob conduction yog feem ntau zoo dua. Qhov no yog vim tias cov kab me me carbon nanotubes muaj cov hluav taws xob hluav taws xob ntau dua, tso cai rau cov hluav taws xob los kis cov tshuab hluav taws xob zoo dua hauv lawv. Nyob rau tib lub sijhawm, lub chairality ntawm cov nanotubes tseem cuam tshuam lawv cov hluav taws xob conduction. Cov pa roj carbon nanotubes nrog cov nkauj tshwj xeeb tuaj yeem ua rau meters, semiconducting, lossis insulating zog, nyob ntawm kev npaj ntawm lawv cov qauv hluav taws xob.
Qhov tseeb vim tias cov pa roj carbon nanotubes muaj cov hluav taws xob zoo xws li muaj kev cuam tshuam zoo, lawv muaj kev cia siab thov kev cia siab hauv ntau thaj teb. Piv txwv li, hauv cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob, cov nanotubes tuaj yeem siv ua cov ntaub ntawv siv hlau los hloov cov xov hlau tsoos, yog li txhim kho cov khoom siv hluav taws xob thiab ruaj khov ntawm cov khoom siv hluav taws xob. Ntxiv mus, cov nanotubes tseem tuaj yeem siv tau los tsim cov khoom siv tau zoo thiab hloov dua siab tshiab, xws li cov roj teeb lithium-ion.
Hauv kev xaus, carbon nanotubes ua tau hluav taws xob conduction, thiab cov cuab yeej no muab chaw loj heev rau lawv cov ntawv thov hauv ntau thaj teb. Nrog kev txhim kho kev kawm txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, peb tau ntseeg tias cov pa roj carbon nanotubes yuav ua lub luag haujlwm ntawm lub neej tom ntej, txhawb kev nce qib thiab kev txhim kho ntawm tib neeg lub zej zog.
