Izinhlayiya eziqhuba i-TPU carbon nanotube – “iparele elisesiqongweni” semboni yokukhiqiza amathayi!

I-Scientific American ichaza lokho; Uma iladi lakhiwe phakathi koMhlaba neNyanga, okuwukuphela kwezinto ezingahamba ibanga elide kangaka ngaphandle kokudonswa yisisindo sazo yi-carbon nanotubes.
Ama-carbon nanotubes ayizinto ze-quantum ezinobukhulu obubodwa ezinesakhiwo esikhethekile. Ukuqhuba kwawo kagesi nokushisa ngokuvamile kungafinyelela izikhathi eziyi-10000 kunezethusi, amandla awo okunamathela aphindwe izikhathi eziyi-100 kunezensimbi, kodwa ubuningi bawo buyi-1/6 kuphela yensimbi, njalo njalo. Angenye yezinto ezisetshenziswa kakhulu ezisezingeni eliphezulu.
Ama-carbon nanotubes angama-coaxial circular tubes akhiwe yizingqimba eziningana kuya kweziningi zama-athomu e-carbon ahlelwe ngephethini eliyi-hexagonal. Gcina ibanga eliqondile phakathi kwezingqimba, cishe u-0.34nm, ububanzi obuvame ukuba phakathi kuka-2 kuya ku-20nm.
I-thermoplastic polyurethane (TPU)isetshenziswa kabanzi emikhakheni efana ne-elekthronikhi, izimoto, kanye nezokwelapha ngenxa yamandla ayo aphezulu okusebenza, ukucutshungulwa kahle, kanye nokuhambisana kwayo nezinto eziphilayo okuhle kakhulu.
Ngokuxuba okuncibilikisiweI-TPUngama-carbon nanotubes adonsa umoya, i-graphene, noma i-carbon nanotubes, izinto ezihlanganisiwe ezinezakhiwo zokudonsa umoya zingalungiswa.
Ukusetshenziswa kwezinto ezihlanganisiwe ze-TPU/carbon nanotube ensimini yezindiza
Amathayi ezindiza yiwona kuphela athintana nomhlabathi ngesikhathi sokusuka nokufika, futhi abelokhu ebhekwa “njengegugu lomqhele” embonini yokukhiqiza amathayi.
Ukwengeza izinto ezihlanganisiwe ze-TPU/carbon nanotube kurubha lokuhamba ngethayi lendiza kuyinika izinzuzo ezifana nokungaguquguquki, ukuhanjiswa kokushisa okuphezulu, ukumelana nokuguguleka okuphezulu, kanye nokumelana nokuklebhuka okuphezulu, ukuze kuthuthukiswe ukusebenza kwethayi. Lokhu kwenza ukuthi ishaja engaguquki ekhiqizwa yithayi ngesikhathi sokusuka kanye nokufika idluliselwe ngokulinganayo emhlabathini, kuyilapho futhi kwenza kube lula ukonga izindleko zokukhiqiza.
Ngenxa yobukhulu be-nanoscale bama-carbon nanotubes, yize engathuthukisa izakhiwo ezahlukahlukene zerabha, kunezinselele eziningi zobuchwepheshe ekusetshenzisweni kwama-carbon nanotubes, njengokungasabalali kahle kanye nokundiza ngesikhathi senqubo yokuxuba irabha.Izinhlayiya eziqhuba i-TPUzinezinga lokusabalala elifanayo kakhulu kune-polymers ye-carbon fiber ejwayelekile, ngenhloso yokuthuthukisa izakhiwo zokulwa nokungaguquguquki kanye nokushisa kwemboni yerabha.
Izinhlayiya eziqhuba i-TPU carbon nanotube zinamandla amahle kakhulu okusebenza, ukuhanjiswa kahle kokushisa, kanye nokumelana okuphansi kwevolumu uma zisetshenziswa emathayini. Lapho izinhlayiya eziqhuba i-TPU carbon nanotube zisetshenziswa ezimotweni zokusebenza ezikhethekile njengezimoto zokuthutha amathangi kawoyela, izimoto zokuthutha izimpahla ezivuthayo neziqhumayo, njll., ukungezwa kwama-carbon nanotube emathayini nakho kuxazulula inkinga yokukhishwa kwe-electrostatic ezimotweni eziphakathi kuya kweziphezulu, kunciphisa ibanga lokubhuleka elimanzi elomile lamathayi, kunciphisa ukumelana nokugingqika kwamathayi, kunciphisa umsindo wamathayi, futhi kuthuthukise ukusebenza okulwa nokungaguquguquki.
Ukusetshenziswa kweizinhlayiya eziqhuba i-carbon nanotubeebusweni bamathayi asebenza kahle kakhulu kubonise izinzuzo zawo zokusebenza ezinhle kakhulu, okuhlanganisa ukumelana nokuguguleka okuphezulu kanye nokushisa, ukumelana nokugingqika okuphansi kanye nokuqina, umphumela omuhle wokulwa nokuma, njll. Ingasetshenziswa ukukhiqiza amathayi asebenza kahle kakhulu, aphephile futhi anobungani nemvelo, futhi anamathemba amakhulu emakethe.
Ukusetshenziswa kokuxuba ama-carbon nanoparticles nezinto ze-polymer kungathola izinto ezintsha ezihlanganisiwe ezinezakhiwo ezinhle kakhulu zemishini, ukuhanjiswa okuhle komoya, ukumelana nokugqwala, kanye nokuvikela nge-electromagnetic. Ama-carbon nanotube polymer composites abhekwa njengezindlela ezingcono kunezinto ezihlakaniphile zendabuko futhi azoba nohlu olubanzi lwezicelo esikhathini esizayo.
