Loaʻa i ka fiber nanotube kalapona (CNTF) nā ʻano o ke kaumaha māmā, ka ikaika kiʻekiʻe a me ka multifunction, a pēlā aku. Ma ke ʻano he hanauna hou o nā mea fiber kūikawā, he koʻikoʻi koʻikoʻi nui ia no ka hoʻomohala ʻana i ka ʻenehana kiʻekiʻe. ʻOiai ʻaʻole i hoʻokumu ka honua i ka ʻoihana nanofibers kalapona a me nā mea composite, akā manaʻoʻiʻo ka ʻoihana kula e lilo ia i hanauna hou o nā mea fiber ikaika kiʻekiʻe hou.

I kēia mau lā iho nei, ua hoʻohana ʻo Matteo Pasquali et al. o ke Kulanui ʻo Rice ma ʻAmelika Hui Pū ʻIa i nā nanotubes kalapona o ke ʻano kiʻekiʻe a me ka lōʻihi e hana i nā olonā nanotube kalapona ma o ka milo ʻana i ka hopena. ʻAʻole wale nā ​​​​loea i māmā, akā he mau waiwai mechanical, uila a me ka maʻalahi hoʻi.

Ua hōʻike ʻia ʻo ka modulus o ka ʻōpio, ka elongation awelika i ka haki a me ka ikaika tensile o ke kaula CNTS i hoʻomākaukau ʻia e nā mea noiʻi he 260GPa, 3.5% a me 4.2GPa, ʻoi aku ka kiʻekiʻe ma mua o ka 3.6GPa o Kevlar®. Eia kekahi, ua hoʻomaikaʻi ʻia kona conductivity i 10.9ms /m, ma kahi o 80% o ke keleawe, ʻo ia hoʻi ka manawa mua i haki ai ka conductivity o ke kaula nanotube kalapona ma o 10MS / m.

Ma ka hoʻohālikelike ʻana i nā waiwai o ke olonā nanotube kalapona me ke olonā kalapona, ke olonā nanotube kalapona i milo pololei ʻia, ke olonā polymer a me ka metala, ua ʻike nā mea noiʻi ua hoʻohui maikaʻi ke olonā nanotube kalapona i hoʻomākaukau ʻia ma kēia hoʻokolohua i ka ikaika tensile o ke olonā kalapona kalepa me ka conductivity uila o ke olonā nanotube kalapona i milo pololei ʻia e like me ka metala, a he conductivity thermal maikaʻi loa.

Ke aʻo ʻia nei nā olonā nanotube kalapona, nona nā ʻumi miliona o nā nanotubes ma kahi ʻāpana kea, no nā Bridges e hoʻoponopono i nā puʻuwai i hōʻino ʻia, nā pilina uila i ka lolo, nā implants cochlear, nā antennas flexible, a me nā noi kaʻa a me nā aerospace. Eia nō naʻe, he pilikia nui nō ia e hoʻomaikaʻi i ka wikiwiki o ka hana ʻana a hoʻemi i ke kumukūʻai hana o nā nanotubes kalapona.
