Cov Nanotubes yog ib hom nanoscale tubular cov ntaub ntawv cov khoom siv muaj cov pa roj atoms. Vim lawv lub zog siab, thermal hluav taws xob conduction, thiab tshuaj lom neeg ruaj khov, lawv tau siv dav hauv ntau daim teb xws li nanelectronics, nanobiomedicine, thiab cov ntaub ntawv science.
Ntawm lawv, thermal conductivity ntawm cov pa roj carbon nanotubes tseem muaj ntau xim. Qhov tseeb, lub thermal conductivity ntawm cov pa roj carbon nanotubes yog nyob deb tshaj plaws rau cov neeg ua pa thermal xws li tooj liab thiab txhuas. Qhov no yog vim muaj kev sib txuam ntawm cov pa roj carbon nanotubes, cov kis tau ceev ceev ntawm cov neeg nqa khoom, thiab khaus thermal oscillations, ntawm lwm yam.
Tshwj xeeb, carbon nanotubes, raws li hom nanomaterial, muaj qhov chaw loj thiab muaj kev kub ceev hloov tau kev ua kom sov. Tsis tas li ntawd, kev nrawm ntawm cov neeg nqa khoom ntawm cov pa roj carbon monoxide Cov kev sim tau qhia tias cov thermal conductivity ntawm cov pa roj carbon nanotubes tuaj yeem ncav cuag ntau dua 3000, uas yog ntau tshaj 3 txog 5 zaug ntawm tooj liab.
Qhov no zoo heev thermal conductivity tau ua cov carbon nanotubes kev tshawb fawb tsom nyob rau hauv ntau thaj teb, xws li cov khoom tswj thermal, thermal interface cov ntaub ntawv, thiab cov cua sov sov. Nyob rau tib lub sijhawm, nws kuj tseem muaj cov ntawv thov dav hauv NanelectRonics thiab kev sib xyaw ua ke.
Txawm li cas los xij, nws yuav tsum raug sau tseg tias kev ua nanotub tam sim no tseem ntsib qee qhov kev cov nyom. Ntawm ib sab tes, kev ua haujlwm thiab npaj cov txheej txheem rau cov nanotubes tseem yuav tsum tau txhim kho ntxiv thiab ua kom zoo tag nrho. Ntawm qhov tod tes, loj-teev ntau lawm cov pa roj carbon nanotubes tseem yog qhov teeb meem nyuaj. Yog li ntawd, yuav ua li cas ntxiv txhim kho kev ua haujlwm ntawm cov pa roj carbon nanotubes thiab txo lawv cov nqi yuav yog qhov kev tshawb fawb yav tom ntej.
Zuag qhia tag nrho, lub thermal conductivity ntawm cov nanotubes yog ib hom khoom tshiab nrog lub peev xwm zoo. Hauv kev tshawb nrhiav yav tom ntej, kev ua yeeb yam thiab kev siv ntawm cov pa roj carbon nanotubes yuav tau tshawb nrhiav kom ua tau zoo dua kev txhim kho thiab kev xav tau ntawm tib neeg.
