Ko nga painga o nga SWCNT e whakamahia ana i roto i te maimoatanga parakaingaki:
Taupānga: Nā te rerekētanga o tōna diameter me te koki helix, ka taea e te ngongo waro he huanga konganuku, he huanga ahua-whakahaere ranei.Na, ka taea te whakamahi ki te hanga ngota ngota-a-iwi, a ka iti te diode ki te nanometer he iti ake i te ao i naianei.Ko te carbon nanotube te kaha teitei, he kaha ake i te maitai.I te wa ano, he tino marama te taumaha o te carbon nanotube, he kotahi noa te whakatekau o te maitai.He nui nga tirohanga tono i roto i te mara o nga rauemi hiato, ka whai mana nui ki te aerospace me te rererangi.
He pai rawa te mahi tukunga parae te waro nanotube.Ka taea te whakamahi i roto i te hanga taputapu whakaatu papatahi me te utu mo te tikanga ngongo irahiko cathode nui me te taumaha.I tua atu, ka taea hoki te whakamahi i te waro nanotube ki te hanga i nga tohu ngota me te karetao nano.He pai ki te whakamahi hei taonga rokiroki hiko penei i te rokiroki hauwai.I roto i te tikanga rongoa, ka taea te whakamahi hei ipu nano me te whakatutuki i te mana whakahaere.
Ko te ngongo mitanano te karaehe mitanano nga tioata graphite tubular, kei roto ko te monolayer, multilayer flakegraphite ranei e karapoti ana i te pou o waenganui i runga i etahi koki torino mingimingi me te ngongo porotakaroa kore.Na te hanga motuhake, he maha nga ahuatanga motuhake ka taea te whakamahi i roto i te hikohiko, miihini, rongoa, kaha, matū, optics me etahi atu waahanga o te hangarau rauemi, tae atu ki nga whakamahinga pea i roto i nga waahanga hoahoa.Ka whakaatuhia e ratou te kaha nui me nga ahuatanga hiko ahurei, a he pai te kawe waiariki.
Ko te kaha me te ngawari o nga ngongo waro ka taea te whakamahi ki te whakahaere i etahi atu hanganga nanoscale, e kii ana ka whai waahi nui ratou ki te hangarau nanotechnology.
