Nā ʻāpana alakaʻi nanotube kalapona TPU - ka "momi ma luna o ka lei aliʻi" o ka ʻoihana hana kaila!

Ua wehewehe ʻo Scientific American i kēlā; Inā kūkulu ʻia kahi alapiʻi ma waena o ka Honua a me ka Mahina, ʻo nā nanotubes kalapona wale nō ka mea hiki ke uhi i kahi mamao me ka ʻole o ka huki ʻia e kona kaumaha ponoʻī.
He mea quantum hoʻokahi-dimensional nā nanotubes kalapona me kahi ʻano kūikawā. Hiki i ko lākou conductivity uila a me ka thermal ke hiki i 10000 mau manawa o ke keleawe, ʻo ko lākou ikaika tensile he 100 mau manawa o ke kila, akā ʻo ko lākou density he 1/6 wale nō o ke kila, a pēlā aku. ʻO lākou kekahi o nā mea ʻoi loa ka pono.
ʻO nā nanotubes kalapona he mau paipu poepoe coaxial i haku ʻia me kekahi mau papa a ʻumi paha o nā ʻātoma kalapona i hoʻonohonoho ʻia i loko o kahi ʻano hexagonal. E mālama i kahi mamao paʻa ma waena o nā papa, ma kahi o 0.34nm, me ke anawaena maʻamau mai 2 a 20nm.
ʻO ka polyurethane thermoplastic (TPU)hoʻohana nui ʻia i nā kahua e like me nā mea uila, nā kaʻa, a me nā lāʻau lapaʻau ma muli o kona ikaika mechanical kiʻekiʻe, ka hiki ke hana maikaʻi, a me ka biocompatibility maikaʻi loa.
Ma ka hoʻohuihui hoʻoheheʻe ʻiaTPUme ka conductive carbon black, graphene, a i ʻole carbon nanotubes, hiki ke hoʻomākaukau ʻia nā mea i hui pū ʻia me nā waiwai conductive.
Ka hoʻohana ʻana o nā mea hui TPU/carbon nanotube blend ma ke kahua mokulele
ʻO nā huila mokulele wale nō nā ʻāpana e pili ana i ka honua i ka wā o ka lele ʻana a me ka pae ʻana, a ua manaʻo mau ʻia ʻo ia ka "lei aliʻi" o ka ʻoihana hana huila.
ʻO ka hoʻohui ʻana i nā mea hui TPU/carbon nanotube i ka rubber heʻe tire mokulele e hāʻawi iā ia i nā pono e like me ka anti-static, ke alakaʻi wela kiʻekiʻe, ke kū'ē ʻana i ke kapa komo, a me ke kū'ē ʻana i ka haehae kiʻekiʻe, i mea e hoʻomaikaʻi ai i ka hana holoʻokoʻa o ka tire. ʻO kēia ka mea e hiki ai i ka hoʻouka static i hana ʻia e ka tire i ka wā o ka lele ʻana a me ka pae ʻana ke hoʻoili like ʻia i ka honua, me ka maʻalahi hoʻi e mālama i nā kumukūʻai hana.
Ma muli o ka nui o nā nanotubes kalapona, ʻoiai hiki iā lākou ke hoʻomaikaʻi i nā ʻano like ʻole o ka rapa, nui nō hoʻi nā pilikia loea i ka hoʻohana ʻana i nā nanotubes kalapona, e like me ka hoʻolaha maikaʻi ʻole a me ka lele ʻana i ka wā o ke kaʻina hana kāwili rapa.Nā ʻāpana alakaʻi TPUʻoi aku ka like o ka nui o ka hoʻopuehu ʻana ma mua o nā polymers fiber kalapona maʻamau, me ka pahuhopu e hoʻomaikaʻi i nā waiwai anti-static a me ka thermal conductivity o ka ʻoihana rubber.
Loaʻa i nā ʻāpana conductive carbon nanotube TPU ka ikaika mechanical maikaʻi loa, ka conductivity thermal maikaʻi, a me ka resistivity haʻahaʻa haʻahaʻa ke hoʻopili ʻia i loko o nā kaila. Ke hoʻohana ʻia nā ʻāpana conductive carbon nanotube TPU i nā kaʻa hana kūikawā e like me nā kaʻa lawe pahu aila, nā kaʻa lawe ukana lapalapa a pahū, a pēlā aku, ʻo ka hoʻohui ʻana o nā nanotubes carbon i nā kaila e hoʻoponopono pū i ka pilikia o ka hoʻokuʻu electrostatic i nā kaʻa waena a kiʻekiʻe, hoʻopōkole hou i ka mamao braking maloʻo a pulu o nā kaila, hoʻemi i ke kū'ē ʻana o ka huila, hoʻemi i ka walaʻau o nā kaila, a hoʻomaikaʻi i ka hana anti-static.
ʻO ka hoʻopili ʻana onā ʻāpana alakaʻi nanotube kalaponama luna o ka ʻili o nā kaila hana kiʻekiʻe ua hōʻike i kona mau pono hana maikaʻi loa, me ke kūpaʻa kiʻekiʻe o ke kapa komo a me ka conductivity thermal, ke kūpaʻa haʻahaʻa a me ka lōʻihi, ka hopena anti-static maikaʻi, a pēlā aku. Hiki ke hoʻohana ʻia e hana i nā kaila hana kiʻekiʻe, palekana a pili i ke kaiapuni, a he ākea nā manaʻolana mākeke.
ʻO ka hoʻopili ʻana i nā nanoparticles kalapona me nā mea polymer hiki ke loaʻa nā mea hui hou me nā waiwai mechanical maikaʻi loa, ka conductivity maikaʻi, ke kūpaʻa i ka corrosion, a me ka pale electromagnetic. Ua manaʻo ʻia nā composites polymer nanotube kalapona he mau koho ʻē aʻe i nā mea akamai kuʻuna a e loaʻa iā lākou kahi ākea ākea o nā noi i ka wā e hiki mai ana.
