Nano Graphene Hmoov CAS 1034343-98-0 Hoobkas Nqe Rau Roj Teeb Qib
Kev piav qhia txog khoom
Graphene oxide muaj ntau pawg uas muaj oxygen nyob rau ntawm nws qhov chaw. Nws muaj cov kuab tshuaj zoo thiab sib raug zoo nrog cov polymers. Cov pa oxygen ntawm cov pab pawg oxygen yog 30-40%, cov dej yaj zoo heev, thiab cov ntsiab lus ntawm monolayer tom qab yaj yog ntau dua 99%. Qhov loj thiab tuab ntawm microchip yog txij li 0.5 txog 3 um thiab txij li 0.55 txog 1.2 nm. Tsis muaj nag lossis daus.
Cov hmoov graphene oxide tau los ntawm kev ziab graphene oxide sol hauv lub tshuab nqus tsev. Thaum ziab graphene oxide, graphene oxide yuav tsis poob cov pab pawg uas muaj oxygen ntawm qhov chaw thiab ua rau muaj kev sib tshooj ntawm cov txheej graphene oxide. Cov hmoov tom qab ziab yog qhov porous thiab spongy. Nws yaj sai thiab tag nrho tom qab ntxiv dej, thiab yuav luag tam sim ntawd rov qab kho cov yam ntxwv ntawm sol qub.
Cov hmoov graphene oxide tuaj yeem faib ncaj qha rau hauv cov kua dej thiab cov kuab tshuaj (ultrasound zoo dua) kom tau txais cov tshuaj sib xyaw thiab ruaj khov (saib phau ntawv qhia txog kev faib tawm rau txoj kev faib tawm tshwj xeeb).

Daim Ntawv Thov
Graphene yog ib qho khoom siv carbon nano ob-seem nrog lub lattice honeycomb hexagonal uas muaj cov pa roj carbon atoms thiab sp² hybrid orbitals.
Graphene muaj cov khoom siv kho qhov muag, hluav taws xob, thiab kho tshuab zoo heev, thiab muaj cov kev siv tseem ceeb hauv kev tshawb fawb txog cov ntaub ntawv, kev ua cov micro-nano, lub zog, biomedicine, thiab kev xa tshuaj. Nws suav hais tias yog cov khoom siv hloov pauv tshiab yav tom ntej.
Cov txheej txheem tsim cov hmoov graphene feem ntau yog cov txheej txheem mechanical peeling, redox method, SiC epitaxial growth method, thiab cov txheej txheem tsim cov yeeb yaj kiab nyias yog cov tshuaj vapor deposition (CVD).
Ntim Khoom & Khaws Cia
Ntim: 10g / 100g / 1kg / ib lub raj mis
Yuav tsum hnav khaub ncaws tiv thaiv thiab hnab looj tes kom zoo kom tsis txhob raug lub cev tib neeg. Yog tias raug, yuav tsum yaug nrog dej ntau ntau tam sim ntawd. Yuav tsum muaj cov txheej txheem ua kom txaus los tiv thaiv kom tsis txhob muaj plua plav. Xyuas kom muaj cua nkag tau zoo thiab teeb tsa cov khoom siv los sau plua plav kom tsis txhob ua pa. Ceev faj thaum thauj khoom thiab tshem khoom kom tiv thaiv kev puas tsuaj rau pob khoom.
Cov khoom no yuav tsum tau khaws cia rau hauv cov thawv kaw ruaj ruaj hauv qhov chaw qhuav, txias, thiab muaj cua nkag zoo, kom nyob deb ntawm cov chaw taws teeb thiab cua sov. Nws yuav tsum tau cais tawm ntawm cov tshuaj txo qis muaj zog thiab cov tshuaj uas yooj yim hlawv. Xyuas kom tseeb tias cov pob khoom tseem zoo thiab tsis muaj qhov xau. Thaum lub pob khoom qhib lawm, cov khoom yuav tsum tau siv tam sim ntawd. Cov pob khoom siv ib nrab yuav tsum tau rov kaw ruaj ruaj. Cov khoom no rhiab heev rau cov dej noo. Yog tias cov khoom nqus cov dej noo, txawm tias yog vim lub pob khoom puas tsuaj lossis qhib qhov chaw cia, nws raug pom zoo tias, tom qab tshem cov pob khoom sab nraud (tsis suav nrog lub hnab ntawv), cov khoom yuav tsum ziab ntawm 80 ° C rau ob peb teev kom txog thaum nws mus txog qhov tsis muaj dej noo.
Raws li qhov xwm txheej ntawm kev ntim khoom thiab kev thauj mus los uas tau hais los saum toj no, cov khoom no yuav siv tau ntev. Yog tias muaj cov kev cai nruj txog cov dej noo, nws yog ib qho tseem ceeb uas yuav tsum ziab raws li Tshooj 5 ua ntej siv.
KEV THAUJ MUS LOS
Cov khoom tsis txwv. Tiv thaiv kom tsis txhob raug tshav ntuj, nag, xau thiab cov ntawv lo uas raug tshem tawm. Txwv tsis pub muab pov tseg. Ua tib zoo tuav thaum thauj khoom thiab tshem tawm kom tsis txhob puas tsuaj. Khaws cia kom deb ntawm cov khoom siv hluav taws xob thiab cua sov. Yuav tsum tsis txhob thauj mus nrog cov tshuaj corrosive.
