Tam sim no, ob qho kev tsim khoom thiab cov ntawv thov ntawm Nanomaterials tau nyiam cov xim los ntawm ntau lub tebchaws. Tuam Tshoj tus Nanotechnology txuas ntxiv mus ua kev nce qib, thiab kev lag luam tsim khoom tau ua tiav hauv Nanoscale Sio2, TiO2, ZNO2, ZOXO3 thiab lwm cov khoom siv hmoov. Txawm li cas los xij, cov txheej txheem ntau lawm thiab cov nqi ntau lawm yog nws cov neeg ua tsis muaj zog, uas yuav cuam tshuam rau cov ntawv thov thoob plaws ntawm nanomaterials. Yog li ntawd, txhim kho tas mus li yog qhov tsim nyog.
Vim yog cov qauv hluav taws xob tshwj xeeb thiab cov hluav taws xob loj ntawm lub ntiaj teb tsis tshua muaj neeg siv tshuaj, lawv cov tshuaj lom neeg muaj ntau yam txawv ntawm lwm cov ntsiab lus. Yog li ntawd, txoj kev npaj ua haujlwm thiab cov thev naus laus zis ntawm cov av tsis tshua muaj zog kuj sib txawv ntawm lwm cov khoom. Cov kev tshawb fawb tseem ceeb suav nrog:
1. Txoj kev cai nag lossis daus, suav nrog nag lossis daus, yog qhov yooj yim los tswj, cov cuab yeej siv tau yooj yim, thiab tuaj yeem tsim khoom high-huv cov khoom lag luam. Tab sis nws yog qhov nyuaj rau lim thiab yooj yim rau kev sib sau ua ke.
2. Hydrothermal Txujci: Ua kom nrawm dua thiab ntxiv dag zog rau cov tshuaj tiv thaiv hydrolysis hauv hydrolysis thiab cov xwm txheej tawg, thiab cov ntawv dispersed nanocrystalline nuclei. Hom no tuaj yeem tau txais cov hmoov tsis zoo nrog kev sib cais thiab cov khoom siv me me, tab sis nws yuav tsum tau siv cov khoom kub siab thiab tsis nyab xeeb ua haujlwm.
3. Gel Txoj Kev: Nws yog ib txoj kev tseem ceeb rau kev npaj cov ntaub ntawv inorganic, thiab ua lub luag haujlwm tseem ceeb hauv inorganic synthesis. Ntawm qhov kub tsawg, organicetallic sib txuas lossis cov organic compound tuaj yeem tsim sol los ntawm polymerization lossis cov yeeb tshuaj gel nyob rau qee yam. Ntxiv cov kev kho cua sov tuaj yeem tsim cov khoom noj ultrarafine mij nrog cov nto cuam tshuam loj thiab ua kom zoo dua. Hom no tuaj yeem nqa tawm hauv qab mob me, ua rau hauv cov hmoov nrog qhov chaw loj dua thiab rov ua dua. Txawm li cas los xij, lub sijhawm kev tawm tsam yog ntev thiab siv sijhawm ntau, ua rau nws nyuaj kom tau raws li qhov yuav tsum tau ua.
4. Khoom theem theem: Kev ntsuas kub siab yog nqa los ntawm cov khoom sib txuas lossis cov khoom sib xyaw theem nrab. Piv txwv li, tsis tshua muaj lub ntiaj teb nitrate thiab oxalic acid tau sib xyaw los ntawm lub ntiaj teb tsis tshua muaj zog, uas yog tom qab ntawd decomposed ntawm qhov kub siab kom tau ultrafine hmoov. Cov qauv no tau ua rau muaj kev cuam tshuam ntau, cov khoom siv yooj yim, thiab kev ua haujlwm yooj yim, tab sis lub txiaj ntsig yooj yim muaj cov morphology thiab tsis xwm yeem.
Cov hau kev no tsis yog qhov tshwj xeeb thiab tsis tuaj yeem siv tau rau kev lag luam. Tseem muaj ntau txoj kev npaj, xws li organic micriaemulsion txoj kev, Cawv thiab lwm yam thiab lwm yam.
