Kuchita kwa Multi-walled carbon nanotubes

Kuchita kwamagetsi

Atomu iliyonse ya kaboni ya sp2 haibridi imakhala ndi ma elekitironi osaphatikizana ndi pi orbital ya pepala, zomwe zimapereka mpweya wabwino kwambiri wamagetsi.Pazipita kachulukidwe panopa mpweya nanotubes akhoza kufika 109Acm-2, amene ndi 1000 nthawi madutsidwe mkuwa.Itha kugwiritsidwa ntchito ngati waya yaying'ono kwambiri, kugwiritsa ntchito komwe kumagwiritsidwa ntchito pano kumagwiritsidwa ntchito ngati ma conductive mu mabatire a lithiamu-ion.Ma semiconducting carbon nanotubes ali ndi ntchito zambiri pazida zamagetsi zamagetsi.

Zimango katundu

sp2 haibridi CC σ bond ndi imodzi mwazinthu zamphamvu kwambiri zomwe zimadziwika pano.Mphamvu zokolola za carbon nanotubes zili mu dongosolo la mazana a GPa, ndipo modulus ya Young ili mu dongosolo la TPa, lomwe ndi lalitali kwambiri kuposa la carbon fiber ndi zida za thupi.Gwiritsani ntchito fiber ndi chitsulo.Akuyembekezeka kusintha kaboni fiber ngati chinthu chatsopano champhamvu.

Kutentha kwachangu

Mpweya wa carbon nanotube heat conduction system uli ndi njira yokulirapo ya phonon yaulere, ndipo ma axial matenthedwe matenthedwe amatha kukhala okwera ngati 6600W / (m · K), yomwe imakhala yopitilira 3 zinthu zomwe zimakhala ndi matenthedwe apamwamba kwambiri pa kutentha kwa diamondi. , yomwe ili m'chilengedwe Chinthu chodziwika bwino kwambiri ndi chothandizira kutentha kutentha mu zipangizo zamagetsi.

M'zaka zaposachedwa, kafukufuku wa carbon nanotubes wawonetsa chiyembekezo chakugwiritsa ntchito pazida za nanoelectronic, ndiye kuti, pomanga zida zamagetsi ndi mawaya ozikidwa pa ma nanotubes a kaboni okhala ndi ma nanometers makumi khumi okha kapenanso ang'onoang'ono, liwiro lozindikira limathamanga kwambiri. kugwiritsa ntchito mphamvu ndikocheperako kuposa ma kaboni nanotube ophatikizika amabwalo ophatikizika apano.

Komanso MWCNT Mipikisano mipanda mpweya nanotubes angagwiritsidwe ntchito kwa conductive, odana ndi malo amodzi, chothandizira chonyamulira, etc.
