Ib leeg-walled carbon nanotubes (SWCNT los yog SWNT) yog tag nrho cov tsim ntawm carbon atoms.Cov qauv geometric tuaj yeem suav tias yog ib txheej ntawm graphene curled, thiab cov qauv txiav txim siab cov khoom.Yog li ntawd, ib leeg-walled carbon nanotubes muaj zoo heev electronics, mechanical, thiab mechanical zog.Kev ua tau zoo, ib leeg-walled carbon nanotubes kuj muaj tshuaj stability.

Ib leeg-phab ntsa carbon raj tuaj yeem siv rau lub peev xwm loj super capacitors:

Tus nqi ntawm lub zog khaws cia nyob rau hauv ib qho hluav taws xob ob txheej capacitor yog txiav txim siab los ntawm qhov ua tau zoo ntawm thaj tsam ntawm cov electrode daim hlau ntawm lub capacitor.Vim tias cov pa roj carbon nanotubes ib leeg muaj qhov loj tshaj plaws ntawm thaj chaw tshwj xeeb thiab kev ua haujlwm zoo, cov electrode npaj los ntawm cov pa roj carbon nanotubes tuaj yeem ua rau muaj peev xwm ua kom lub zog ntawm cov hluav taws xob ob txheej capacitor.

Raws li cov yam ntxwv ntawm cov pa roj carbon nanotubes, nws muaj qhov tseem ceeb adsorption rau ob qho tib si kua thiab roj.Cov pa roj carbon nanotubes khaws cov hydrogen los ntawm kev siv cov yam ntxwv ntawm lub cev adsorption lossis tshuaj lom neeg adsorption ntawm hydrogen hauv cov ntaub ntawv uas muaj qhov loj ntawm qhov chaw thiab qhov pore.
