Kev tshawb fawb Asmeskas piav qhia tias; Yog tias tus ntaiv tau tsim los ntawm lub ntiaj teb thiab lub hli, tsuas yog cov khoom siv uas tuaj yeem ncua deb li deb tsis tau rub los ntawm nws tus kheej qhov hnyav yog carbon nanotubes.
Cov pa roj carbon nanotubes yog cov khoom siv ib-dimensional quantum nrog cov qauv tshwj xeeb. Lawv cov hluav taws xob thiab thermal conductivity feem ntau tuaj yeem ncav cuag 10000 npaug ntawm tooj liab, lawv lub zog tensile yog 100 npaug ntawm cov hlau, tab sis lawv qhov ceev tsuas yog 1/6 ntawm cov hlau, thiab lwm yam. Lawv yog ib qho ntawm cov khoom siv tau zoo tshaj plaws.
Cov pa roj carbon nanotubes yog coaxial ncig cov hlab uas muaj li ntawm ob peb mus rau kaum ob txheej ntawm carbon atoms teem nyob rau hauv ib tug hexagonal qauv. Tuav qhov kev ncua deb ntawm cov khaubncaws sab nraud povtseg, kwv yees li 0.34nm, nrog ib txoj kab uas hla feem ntau yog li ntawm 2 txog 20nm.
Thermoplastic polyurethane (TPU)yog dav siv nyob rau hauv teb xws li electronics, automotive, thiab tshuaj vim nws cov neeg kho tshuab siab zog, zoo processability, thiab zoo heev biocompatibility.
Los ntawm meltingTPUnrog cov pa roj carbon dub, graphene, lossis carbon nanotubes, cov ntaub ntawv sib xyaw nrog cov khoom siv hluav taws xob tuaj yeem npaj tau.
Daim ntawv thov ntawm TPU / carbon nanotube muab cov ntaub ntawv sib xyaw hauv thaj chaw aviation
Cov log tsheb dav hlau tsuas yog cov khoom sib txuas nrog hauv av thaum lub sij hawm tawm mus thiab tsaws, thiab ib txwm raug suav tias yog "pob zeb diamond" ntawm kev lag luam log tsheb.
Ntxiv TPU / carbon nanotube muab cov ntaub ntawv sib xyaw rau aviation log tsheb tread rubber muab nws qhov zoo xws li kev tiv thaiv zoo li qub, thermal conductivity, siab hnav tsis kam, thiab ua kua muag siab, txhawm rau txhim kho tag nrho cov kev ua haujlwm ntawm lub log. Qhov no ua rau tus nqi zoo li qub uas tsim los ntawm lub log tsheb thaum lub sijhawm nqa thiab tsaws kom sib npaug sib npaug rau hauv av, thaum tseem ua rau nws yooj yim dua los txuag cov nqi tsim khoom.
Vim tias qhov loj me me ntawm cov pa roj carbon nanotubes, txawm hais tias lawv tuaj yeem txhim kho ntau yam khoom ntawm cov roj hmab, kuj tseem muaj ntau yam kev sib tw hauv kev siv cov pa roj carbon nanotubes, xws li kev tsis sib haum xeeb tsis zoo thiab ya thaum lub sij hawm sib xyaw roj hmab.TPU conductive haismuaj qhov sib txawv ntawm qhov sib txawv ntau dua li cov pa roj carbon fiber ntau polymers, nrog rau lub hom phiaj ntawm kev txhim kho cov khoom tiv thaiv zoo li qub thiab thermal conductivity ntawm kev lag luam roj hmab.
TPU carbon nanotube conductive particles muaj zoo heev mechanical zog, zoo thermal conductivity, thiab tsawg ntim resistivity thaum siv nyob rau hauv lub log tsheb. Thaum TPU carbon nanotube conductive hais yog siv nyob rau hauv tshwj xeeb kev ua hauj lwm tsheb xws li roj tank thauj tsheb, flammable thiab explosive khoom thauj tsheb, thiab lwm yam, ntxiv cov pa roj carbon nanotubes rau log tsheb kuj daws tau cov teeb meem ntawm electrostatic paug nyob rau hauv nruab nrab mus rau siab kawg tsheb, ntxiv shortens lub qhuav ntub braking deb ntawm cov log tsheb, txo cov log tsheb rolling tsis kam, kev ua tau zoo.
Daim ntawv thov ntawmcarbon nanotube conductive haisNyob rau saum npoo ntawm cov log tsheb uas muaj kev ua tau zoo tau pom tias nws qhov kev ua tau zoo zoo, nrog rau kev hnav tsis kam thiab thermal conductivity, tsis tshua muaj rolling kuj thiab durability, zoo anti-static nyhuv, thiab lwm yam. Nws tuaj yeem siv los tsim cov log tsheb ua haujlwm siab, muaj kev nyab xeeb thiab ib puag ncig zoo, thiab muaj kev lag luam dav dav.
Daim ntawv thov ntawm kev sib xyaw cov pa roj carbon nanoparticles nrog cov ntaub ntawv polymer tuaj yeem tau txais cov ntaub ntawv sib xyaw tshiab nrog cov khoom siv zoo heev, zoo conductivity, corrosion resistance, thiab electromagnetic shielding. Cov pa roj carbon nanotube polymer composites raug suav tias yog lwm txoj hauv kev rau cov khoom ntse ntse thiab yuav muaj ntau qhov kev siv ntau ntxiv rau yav tom ntej.
