Carbon nanotube fiber wanda ƙarfinsa ya zarce fiber arylon da ƙarfin lantarki ya wuce 10MS/m a karon farko.

Carbon nanotube fiber (Farashin CNTF) yana da halaye na nauyin nauyi, babban ƙarfi da multifunction, da dai sauransu. A matsayin sabon ƙarni na kayan fiber na musamman, yana da mahimmancin mahimmanci don haɓaka fasaha mai mahimmanci. Ko da yake har yanzu duniya ba ta samar da carbon nanofibers da masana'antar kayan haɗaka ba, amma masana kimiyya gabaɗaya sun yi imanin cewa zai zama ƙarni na gaba na sabbin kayan fiber masu ƙarfi.




Kwanan nan, Matteo Pasquali et al. na Jami'ar Rice a Amurka ta yi amfani da carbon nanotubes masu inganci da tsayi mai tsayi don yin fiber nanotube fibers ta hanyar juyawa.. Fiber ɗin ba kawai nauyi ba ne, amma kuma suna da injina mai kyau, lantarki da sassauƙa Properties.




An ba da rahoton cewa ma'auni na matasa, Matsakaicin elongation a karya da ƙarfin ƙarfi na fiber CNTS da masu binciken suka shirya sun kasance 260GPa, 3.5% da 4.2GPa, nisa fiye da Kevlar® 3.6GPa. Haka kuma, an inganta halayensa zuwa 10.9ms/m, game da 80% na jan karfe, wanda kuma shine karo na farko da sarrafa wutar lantarki na carbon nanotube fiber ya karye ta hanyar 10MS/m.




Ta hanyar kwatanta kaddarorin fiber nanotube na carbon nanotube tare da fiber carbon, kai tsaye spun carbon nanotube fiber, polymer fiber da karfe, Masu binciken sun gano cewa fiber na carbon nanotube da aka shirya a cikin wannan gwaji daidai ya haɗu da ƙarfin ƙarfi na fiber carbon na kasuwanci tare da ƙarfin lantarki na fiber carbon nanotube kai tsaye mai kama da ƙarfe., kuma yana da kyakkyawan yanayin thermal conductivity.




Karbon nanotube fibers, wanda ke da dubun-dubatar nanotubes a fadin wani yanki, ana nazarin Gada don gyara zukata da suka lalace, hanyoyin sadarwa na lantarki zuwa kwakwalwa, cochlear implants, m eriya, da aikace-aikacen motoci da sararin samaniya. Duk da haka, har yanzu babban kalubale ne don inganta yawan samarwa da rage farashin samar da carbon nanotubes.
