Nanotube waro whakaata tākaka i rahi ake i te arylon whakaata tākaka me te kaha o te kawe ia i te 10o MS/m mō te wā tuatahi

wā:2020-09-14 Ngā Taunga:

Nanotube waro whakaata tākaka (CNTF) ko te āhuatanga o te taumaha marama, kaha nui me te multifunction, etc. Hei whakatupuranga hou o whakaata tākaka motuhake, he nui nga rautaki tikanga ake mo te whanaketanga o te hangarau whakamutunga. Ahakoa kaore anō te ao kia hanga i te nanofibers waro, ko te academia ia o te tangata e whakapono ana, ko te whakatupuranga panuku o te kaha o te tino whakaata tākaka o runga rawa.




Aita i maoro a'e, Matteo Pasquali et al. te Whare Wānanga o Raihi i te taha o te nanotubes waro o Amerika, i te roanga o te tino nanotube fibers. Ehara te fibers i te marama ki te taumaha, engari he pai hoki, ngā āhuatanga hiko, ngohengohe.




Kua pūrongotia te modulus o te taitama, elongation toharite i te kotinga me te tensile kaha o te CNTS whakaata tākaka i whakaritea e te utuhia, 3.5% me 4.2 GPa, tawhiti ake i te Kevlar® 3.6 GPa. Ano hoki, kua kawe ia tana pai ki te 10.9 ms/m, e pā ana ki 80% o kapa, ko te wa hoki tenei i te tuatahi, kua pakaru te kawe ia o te nanotube waro i te 10MS/m.




Mā te taurite i ngā āhuatanga o te nanotube waro whakaata tākaka ki te whakaata tākaka waro, takahurihuri waro nanotube whakaata tākaka, waerau whakaata tākaka me te konganuku, i kitea e te utuhia he mea nanotube te whakaata tākaka waro i roto i tēnei whakamātautau tāniko paheko ai i te kaha o te tensile waro, i te taha o te whakaata tākaka, i te kawe ia waro, i te mea he rite tonu ki te konganuku, he pai hoki tākai kawe ia.




Te nanotube waro fibers, ko te mo tekau o te miriona o te nanotubes puta noa i te wāhanga-whiti, e ako ana mō te Arawhata hei tapi i te manawa tūkino, atanga hiko ki te roro, awa implants, ngohengohe antennas, me ngā wakaaunoa me ngā taupānga aerospace. Heoi, he nui tonu te wero ki te whakapai i te mokatere o te huanga, a, ka whakaiti i te utu nanotubes.
