Carbon nanotube fiber (CNTF) ine hunhu hwehuremu huremu, simba rakawanda uye multifunction, etc. Sechizvarwa chitsva cheyakakosha fiber material, ine hukuru hunokosha hunokosha pakuvandudza teknolojia yepamusoro. Kunyangwe nyika isati yaumba kabhoni nanofibers uye composite zvinhu indasitiri, asi iyo academia inowanzo tenda kuti ichave chizvarwa chinotevera cheakakwirira-simba fiber zvinhu.

Munguva pfupi yapfuura, Matteo Pasquali et al. weRice University kuUnited States akashandisa kabhoni nanotubes emhando yepamusoro uye kureba kugadzira kabhoni nanotube fiber kuburikidza nesolution spinning. Iyo fiber haisi chiedza chete muhuremu, asiwo ine yakanaka mechanical, magetsi uye inoshanduka zvinhu.

Zvinonzi modulus yevadiki, avhareji elongation panguva yekuzorora uye kusimba kwesimba reCNTS faibha yakagadzirwa nevaongorori yaive 260GPa, 3.5% uye 4.2GPa, yakakwira zvakanyanya kupfuura Kevlar®'s 3.6GPa. Uyezve, conductivity yayo yakagadziridzwa kusvika 10.9ms / m, inenge 80% yemhangura, iyo inguva yekutanga iyo conductivity ye carbon nanotube fiber yakaputsika kuburikidza ne10MS / m.

Nekuenzanisa zvimiro zvekabhoni nanotube fiber ine kabhoni faibha, yakananga spun kabhoni nanotube faibha, polymer faibha nesimbi, vaongorori vakawana kuti kabhoni nanotube faibha yakagadzirwa muchiyedzo ichi inonyatso batanidza kusimba kwekutengesa kabhoni fiber nemagetsi conductivity yekuruka yakananga kabhoni nanotube fiber yakafanana nesimbi, uye ine yakanakisa yekupisa conductivity.

Iyo kabhoni nanotube fibers, ine makumi emamiriyoni e nanotubes pamhiri-chikamu, ari kudzidzwa kuBridges kugadzirisa moyo yakakuvadzwa, magetsi anopindirana kuuropi, cochlear implants, anochinjika antenna, uye mota uye aerospace application. Nekudaro, ichiri dambudziko rakakura kuvandudza mwero wekugadzira uye kuderedza mutengo wekugadzira kabhoni nanotubes.
