Nanomaterials yog dab tsi?

Nanomaterials tuaj yeem txhais tau tias yog cov khoom muaj, yam tsawg kawg nkaus, ib qho sab nraud ntsuas 1-100nm.Cov lus txhais tau muab los ntawm European Commission hais tias qhov loj me me ntawm qhov tsawg kawg yog ib nrab ntawm cov khoom hauv tus lej loj yuav tsum ntsuas 100nm lossis qis dua.

Nanomaterials tuaj yeem tshwm sim ib txwm muaj, tsim los ntawm cov khoom siv los ntawm cov tshuaj tiv thaiv combustion, lossis raug tsim los ntawm kev tsim vaj tsev los ua haujlwm tshwj xeeb.Cov ntaub ntawv no tuaj yeem muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg rau lawv cov khoom sib txawv.

Dab tsi yog kev siv ntawm Nanomaterials?
Vim muaj peev xwm tsim cov ntaub ntawv hauv ib txoj hauv kev los ua lub luag haujlwm tshwj xeeb, kev siv nanomaterials spans thoob plaws ntau yam kev lag luam, los ntawm kev kho mob thiab tshuaj pleev ib ce rau ib puag ncig kev txuag thiab huab cua purification.

Kev kho mob, piv txwv li, siv nanomaterials nyob rau hauv ntau txoj kev, nrog rau ib qho kev siv loj yog kev xa tshuaj.Ib qho piv txwv ntawm cov txheej txheem no yog qhov uas nanoparticles tau tsim los pab kev thauj mus los ntawm cov tshuaj khomob ncaj qha rau kev loj hlob qog noj ntshav, nrog rau xa cov tshuaj mus rau thaj chaw ntawm cov hlab ntsha uas puas lawm txhawm rau txhawm rau tiv thaiv kab mob plawv.Cov pa roj carbon nanotubes tseem raug tsim los siv rau hauv cov txheej txheem xws li ntxiv cov tshuaj tiv thaiv kab mob rau cov nanotubes los tsim cov kab mob sensors.

Hauv aerospace, cov pa roj carbon nanotubes tuaj yeem siv rau hauv morphing ntawm aircraft tis.Cov nanotubes yog siv rau hauv daim ntawv sib xyaw kom khoov teb rau kev siv hluav taws xob hluav taws xob.

Lwm qhov, cov txheej txheem khaws cia ib puag ncig siv cov nanomaterials ib yam nkaus - qhov no, nanowires.Cov ntawv thov raug tsim los siv cov nanowires - zinc oxide nanowires- hauv cov hnub ci hloov tau yooj yim thiab ua lub luag haujlwm hauv kev kho cov dej qias neeg.

Piv txwv ntawm Nanomaterials thiab Industries lawv tau siv hauv
Kev siv cov nanomaterials yog dav siv nyob rau hauv ntau yam kev lag luam thiab cov khoom siv.

Hauv kev lag luam tshuaj pleev ib ce, cov ntxhia nanoparticles - xws li titanium oxide - yog siv rau hauv cov tshuaj pleev thaiv hnub, vim tias tsis muaj kev ruaj ntseg uas cov tshuaj tiv thaiv UV muaj nyob rau lub sijhawm ntev.Ib yam li cov khoom siv loj, titanium oxide nanoparticles tuaj yeem muab kev tiv thaiv UV zoo dua thaum tseem muaj qhov zoo ntxiv ntawm kev tshem tawm cov tshuaj pleev ib ce tsis zoo uas cuam tshuam nrog cov tshuaj pleev thaiv hnub hauv lawv daim ntawv nano.

Kev lag luam kev ua kis las tau tsim cov puav ncaws pob uas tau ua nrog cov pa roj carbon nanotubes, ua rau cov puav sib zog yog li txhim kho lawv cov kev ua tau zoo.Kev siv cov nanomaterials ntxiv nyob rau hauv qhov kev lag luam no tuaj yeem raug txheeb xyuas los ntawm kev siv tshuaj tua kab mob nanotechnology hauv cov khoom xws li cov phuam da dej thiab cov ntaub so ntswg siv los ntawm cov neeg ncaws pob, txhawm rau tiv thaiv cov kab mob los ntawm cov kab mob.

Nanomaterials kuj tau tsim los siv rau hauv tub rog.Ib qho piv txwv yog kev siv cov xim nanoparticles mobile pigment yog siv los tsim ib daim ntawv zoo ntawm camouflage, los ntawm kev txhaj tshuaj rau hauv cov khoom ntawm cov tub rog cov khaub ncaws.Tsis tas li ntawd, cov tub rog tau tsim cov tshuab sensor siv nanomaterials, xws li titanium dioxide, uas tuaj yeem ntes cov tshuaj lom neeg.

Kev siv cov nano-titanium dioxide kuj tseem siv tau rau hauv cov txheej txheem los tsim cov khoom siv tu tus kheej, xws li cov rooj zaum yas vaj.Ib zaj duab xis kaw dej yog tsim rau ntawm txheej, thiab txhua yam av dissolves hauv zaj duab xis, tom qab da dej tom ntej no yuav tshem tawm cov av thiab qhov tseem ceeb ntxuav cov rooj zaum.

Qhov zoo ntawm Nanomaterials
Cov khoom ntawm nanomaterials, tshwj xeeb tshaj yog lawv qhov loj me, muaj ntau qhov zoo sib txawv piv rau cov ntaub ntawv ntau ntawm cov ntaub ntawv, thiab lawv cov kev ua tau zoo ntawm kev muaj peev xwm los kho lawv rau cov kev cai tshwj xeeb accentuates lawv cov txiaj ntsig.Ib qho ntxiv kom zoo dua yog lawv cov porosity siab, uas ntxiv rau qhov kev thov rau lawv siv nyob rau hauv ntau qhov kev lag luam.

Hauv kev lag luam hluav taws xob, kev siv nanomaterials yog qhov zoo uas lawv tuaj yeem ua cov txheej txheem uas twb muaj lawm ntawm kev tsim hluav taws xob - xws li cov hnub ci vaj huam sib luag - ntau dua thiab siv tau zoo, nrog rau qhib txoj hauv kev tshiab rau ob qho tib si siv thiab khaws lub zog. .

Nanomaterials kuj tau teeb tsa los ua kom paub ntau qhov zoo hauv cov khoom siv hluav taws xob thiab kev lag luam suav.Lawv txoj kev siv yuav tso cai rau kev nce qib ntawm qhov tseeb ntawm kev tsim hluav taws xob hauv hluav taws xob ntawm qib atomic, pab tsim cov khoom siv hluav taws xob ntau.

Qhov loj heev saum npoo-rau-ntim piv ntawm nanomaterials yog tshwj xeeb tshaj yog pab tau nyob rau hauv lawv cov kev siv nyob rau hauv kev kho mob teb, uas tso cai rau lub bonding ntawm hlwb thiab active cov khoom xyaw.Qhov no ua rau pom tseeb qhov txiaj ntsig ntawm kev nce ntxiv ntawm qhov ua tau zoo ntawm kev tiv thaiv ntau yam kab mob.
