Scientific American inotsanangura kuti; Kana manera akavakwa pakati pePasi neMwedzi, chinhu chega chinogona kureba chinhambwe chakadaro chisina kudhonzwa neuremu hwayo icarbon nanotubes.
Carbon nanotubes chinhu chimwe-dimensional quantum zvinhu zvine chimiro chakakosha. Maitiro avo emagetsi uye ekupisa anogona kazhinji kusvika 10000 nguva yemhangura, simba ravo rekusimba rakapetwa ka100 kune resimbi, asi density yavo inongova 1/6 yesimbi, zvichingodaro. Ndiyo imwe yeanonyanya kushanda ekucheka-kumucheto zvinhu.
Carbon nanotubes icoaxial denderedzwa machubhu anoumbwa akati wandei kusvika kune gumi nemaviri akaturikidzana emaatomu ekabhoni akarongwa mune hexagonal pateni. Chengetedza chinhambwe chakasarudzika pakati pezvikamu, zvingangoita 0.34nm, ine dhayamita inowanzobva pa2 kusvika pa20nm.
Thermoplastic polyurethane (TPU)inoshandiswa zvakanyanya muminda yakadai semagetsi, mota, uye mushonga nekuda kwesimba rayo remuchina, yakanaka processability, uye yakanakisa biocompatibility.
Nekusanganisa kunyungudukaTPUine conductive kabhoni dema, graphene, kana kabhoni nanotubes, zvinhu zvakaumbwa zvine conductive zvimiro zvinogona kugadzirwa.
Kushandiswa kweTPU/carbon nanotube blend composite zvinhu mumunda wendege
Matayi endege ndizvo chete zvikamu zvinosangana nepasi panguva yekusimuka nekumhara, uye zvagara zvichionekwa se "korona jewel" yeindasitiri yekugadzira matayi.
Kuwedzera TPU/carbon nanotube blend composite materials kune aviation tire tread rabha inopa zvakanakira senge anti-static, high thermal conductivity, high wear resistance, uye yakakwira kubvarura kuramba, kuitira kuvandudza kuita kwese kwetai. Izvi zvinoita kuti iyo static charge inogadzirwa nevhiri panguva yekusimuka uye kumhara kuti ifambiswe zvakaenzana pasi, ukuwo zvichiita kuti zvive nyore kuchengetedza mutengo wekugadzira.
Nekuda kwehukuru hwe nanoscale yekabhoni nanotubes, kunyangwe vachigona kuvandudza akasiyana siyana erabha, kune zvakare akawanda ehunyanzvi matambudziko mukushandiswa kwekabhoni nanotubes, senge kushata dispersibility uye kubhururuka panguva yekusanganiswa kwerabha.TPU conductive particlesiva nemwero wakawanda wekupararira kwakafanana pane general kabhoni fiber polymers, nechinangwa chekuvandudza anti-static uye yekupisa conductivity zvimiro zveindasitiri yerabha.
TPU kabhoni nanotube conductive particles ine yakanakisa mechini simba, yakanaka yekupisa conductivity, uye yakaderera vhoriyamu resistivity kana yaiswa mumatayari. Kana TPU kabhoni nanotube conductive zvimedu zvichishandiswa mumotokari dzinoshanda dzakaita semota dzekutakura mafuta matangi, mota dzinopfuta uye dzinoputika dzinotakura zvinhu, nezvimwewo, kuwedzera kwekabhoni nanotubes kumatayi kunogadzirisawo dambudziko rekubuda kwemagetsi mukati kusvika kumota dzepamusoro, kunowedzera kupfupisa mvura yakaoma braking kureba kwematayi, inoderedza tireyi yekutenderedza kumira, kuderedza tireyi yekupoterera uye kumisa ruzha.
Kushandiswa kwecarbon nanotube conductive particlespamusoro pematairi epamusoro-soro yakaratidza kunaka kwayo kwekushanda kwakanakisisa, kusanganisira kushandiswa kwepamusoro-soro uye kupisa kwemhepo, kuderera kwekugadzirisa uye kusimba, kunaka kwe-anti-static effect, nezvimwewo. Inogona kushandiswa kugadzira matai akakwirira, akachengeteka uye ane ushamwari, uye ane tarisiro yakakura yemusika.
Iko kushandiswa kwekusanganisa kabhoni nanoparticles nezvinhu zvepolymer kunogona kuwana zvinhu zvitsva zvakaumbwa zvine hunhu hwemakinika, yakanaka conductivity, corrosion resistance, uye electromagnetic shielding. Carbon nanotube polymer composites inoonekwa sedzimwe nzira dzechinyakare smart zvinhu uye ichave nekuwedzera kuwanda kwekushandisa mune ramangwana.
