Carbon nanotubes (CNTs) yog tubular nanostructures tsim los ntawm dov li ib los yog ntau txheej ntawm graphite nplooj ntawv. Lawv muaj cov khoom siv hluav taws xob tshwj xeeb, hluav taws xob, thiab thermal, yog li ua si ntau lub luag haujlwm hauv cov ntaub ntawv tshawb fawb thiab kev siv engineering.
Ua ntej, CNTs nthuav tawm cov hluav taws xob zoo heev. Ib leeg-cov pa roj carbon nanotubes muaj phab ntsa tuaj yeem ua tiav cov khoom siv hluav taws xob siab heev, ua rau lawv tsim nyog rau kev txhim kho cov conductive polymers, cov khoom sib xyaw, lossis cov khoom siv hluav taws xob. Hauv cov sensors, supercapacitors, thiab cov khoom siv hluav taws xob hloov tau yooj yim, CNTs feem ntau siv los ua cov khoom siv hluav taws xob zoo heev los txhim kho kev ua haujlwm tag nrho.
Qhov thib ob, CNTs muaj cov cuab yeej tshwj xeeb. Lawv lub zog tensile thiab Young's modulus nyob deb tshaj cov hlau, ua rau lawv yog ib qho tseem ceeb muab tub lim rau ntxiv cov khoom sib xyaw. Qhia CNTs rau hauv polymer lossis hlau matrices tuaj yeem txhim kho lub zog, toughness, thiab hnav tsis kam ntawm cov ntaub ntawv thaum tuav lawv lub teeb yuag. Qhov kev txhawb zog no yog siv dav hauv aerospace, automotive, thiab cov ntaub ntawv tsim qauv.
Tsis tas li ntawd, CNTs kuj muaj cov thermal conductivity zoo heev thiab kev ruaj ntseg tshuaj, ua rau lawv tsim nyog rau cov khoom siv thermal tswj, cov khoom siv hluav taws xob, thiab kev txhawb nqa catalyst. Hauv thaj chaw khaws cia lub zog, thaj chaw siab tshwj xeeb thiab cov qauv kev sib txuas ntawm CNTs ua rau lawv yog cov khoom siv zoo tshaj plaws rau lithium- ion roj teeb, supercapacitors, thiab roj hlwb. Hauv thaj chaw ib puag ncig thiab tshuaj lom neeg, CNTs tuaj yeem siv los ua catalyst txhawb lossis adsorbents rau kev tshem tawm cov pa phem thiab cov tshuaj tiv thaiv acceleration.
