2023.8 Ua tiav daim ntawv nanocomposite

Raws li tib neeg qhov kev thov rau cov khoom siv tshiab thiab ib puag ncig tus phooj ywg tseem nce ntxiv, txoj kev loj hlob zeem muag ntawm nanocomposite lim ntawv yog qhov dav heev. Cia peb saib ze dua ntawm cov txiaj ntsig thiab kev siv ntawm cov thev naus laus zis no. Ib qho txiaj ntsig tseem ceeb ntawm nanocomposite lim ntawv yog nws lub peev xwm los ua kom pom kev ua haujlwm zoo. Kev lim dej tuaj yeem txhim kho tau zoo los ntawm kev sib xyaw nanomaterials, xws li nanoparticles lossis nanofibers, rau hauv cov ntawv lim ntawv matrix. Cov nanomaterials muaj cov khoom tshwj xeeb xws li thaj chaw siab, qhov pore me me, thiab cov khoom siv hluav taws xob uas tso cai rau lawv tshem tawm cov khoom me me, kab mob, kab mob, thiab lwm yam kab mob los ntawm cov kua lossis roj. Qhov ua kom pom kev ua tau zoo ntawm nanocomposite lim ntawv ua rau nws haum rau ntau yam kev siv.

Lwm qhov txiaj ntsig tseem ceeb ntawm nanocomposite lim ntawv yog nws cov khoom siv tshuaj tua kab mob. Nanomaterials embedded nyob rau hauv cov ntawv lim tuaj yeem pom cov kab mob tua kab mob thiab cuam tshuam kev loj hlob thiab kev loj hlob ntawm cov kab mob thiab kab mob. Hauv kev lag luam xws li kev noj qab haus huv, ntim khoom noj thiab kev kho dej, qhov chaw tswj kom tsis muaj menyuam yog qhov tseem ceeb, nanocomposite lim ntawv tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev muab qhov chaw nyab xeeb thiab noj qab haus huv rau tib neeg. Cov cuab yeej tshuaj tua kab mob no pab tiv thaiv kev kis kab mob thiab txhim kho cov qauv kev nyiam huv hauv cov khoom thiab cov chaw. Kev tiv thaiv ib puag ncig yog qhov teeb meem ceev hauv ntiaj teb niaj hnub no, thiab nanocomposite lim ntawv tuaj yeem pab txhawb kev txhim kho kom ruaj khov. Tsis zoo li cov khoom siv lim dej pov tseg, nanocomposite lim cov ntaub ntawv feem ntau rov siv tau thiab biodegradable. Cov yam ntxwv no txo ​​qis kev tsim khoom pov tseg thiab txo qis ib puag ncig cuam tshuam nrog kev siv cov lim dej pov tseg. Los ntawm kev siv nanocomposite lim ntawv, cov lag luam tuaj yeem txais kev coj ua zoo ib puag ncig thiab pab txhawb rau yav tom ntej ntsuab.

Tsis tas li ntawd, qhov versatility ntawm nanocomposite lim ntawv muab nws ntau yam ntawm daim ntawv thov kev cia siab. Ntxiv nrog rau kev lag luam kho mob thiab zaub mov kev nyab xeeb uas twb tau hais lawm, cov ntaub ntawv lim dej nanocomposite pom kev siv hauv huab cua huv, kev kho dej, kev ua tshuaj, thiab ntau qhov chaw. Lub peev xwm los tsim cov khoom ntawm nanocomposite lim cov ntaub ntawv rau cov kev cai tshwj xeeb ua rau nws muaj ntau yam kev daws teeb meem nrog kev lag luam loj loj. Qhov kev ua tau zoo no qhib tau ntau lub sijhawm ua lag luam rau cov tuam txhab thoob plaws ntau yam kev lag luam.

Hauv cov ntsiab lus, txoj kev vam meej ntawm nanocomposite lim ntawv muaj ntau yam txiaj ntsig thiab muaj kev lag luam loj heev. Nws txhim kho pom kev ua haujlwm zoo, cov khoom siv tshuaj tiv thaiv kab mob thiab cov khoom zoo ib puag ncig ua rau nws qhov kev xaiv zoo nkauj rau kev lag luam tab tom nrhiav kev daws teeb meem tshiab. Kev siv ntau yam ntxiv txhim kho kev lag luam muaj peev xwm ntawm nanocomposite lim ntawv. Los ntawm kev nqis peev hauv kev txhim kho thiab kev lag luam ntawm cov thev naus laus zis no, cov tuam txhab tuaj yeem ua tau raws li qhov xav tau ntau dua rau kev pom zoo dua, pab txhawb kom muaj kev nyab xeeb dua, muaj kev noj qab haus huv ib puag ncig, thiab tso lawv tus kheej ua cov thawj coj tshiab hauv lawv cov kev lag luam.
