Diyaarinta Macro hufan ee Graphene waa la xaqiiqsaday

Graphene waa walax cusub oo laba-geesood leh oo ka kooban hal lakab oo sp2 atamka kaarboon, kaas oo leh sifooyin farsamo, koronto iyo kulayl aad u wanaagsan. Iyada oo leh sifooyinkeeda gaarka ah, graphene waxay muujisay awood codsi oo weyn oo dhinacyo badan leh, waxayna noqotay goob cilmi baaris oo cilmi baaris ah maanta.

Recently, kooxda cilmi sayniska Sun Youyi ee North University of China isticmaalay colloidal kimikada mugga celinaya, oo ay weheliso hab cusub oo laba-cabbir xaashi nanomaterial xariijimo, si loo gaaro diyaarinta Macro hufan ee graphene.

Sida laga soo xigtay warbixinnada, hababka diyaarinta graphene ee caadiga ah waa habka REDOX, habka xariijinta farsamada, habka uumiga dhigaalka, habka xarigga sare, iwm, kuwaas oo habka REDOX uu yahay habka ugu muhiimsan ee wax soo saarka warshadaha ee graphene hadda. Kooxda cilmi-baaristu waxay qaateen habka xumbo-caawinta dareeraha wejiga farsamada, iyadoo la adeegsanayo jiilka goobta ee goobooyinka u dhexeeya lakabyada graphite si loo ballaariyo farqiga u dhexeeya lakabyada graphite, beddelaya habka dhaqanka ee aashitada xooggan iyo ballaarinta lakabka oksaydheynta xooggan, hoos u dhigista xoogga van der Waals ee u dhexeeya xaashiyaha graphite, oo lagu daro kolloidal kiimikaad celiska mugga kiimikada, kor u qaadida awoodda dareeraha ee hoos yimaada heerka dareeraha. Si loo xalliyo dhibaatooyinka habka adag, cilladaha waaweyn iyo dhalidda hoose ee graphene oo loo diyaariyey habka farsamaynta.

Habkani ma aha oo kaliya habka diyaarinta fudud, xakamaynta wanaagsan ee qaab dhismeedka graphene iyo xasilloonida dufcadda, laakiin sidoo kale waxay isticmaashaa asiidhyo xooggan iyo oxidants xooggan waxayna soo saartaa biyaha wasakhda ah ee yar, waxayna leedahay faa'iidooyinka ilaalinta deegaanka cagaaran, qiimaha hooseeya ee graphene, cillado yar, iyo qaabdhismeed wanaagsan. Sida laga soo xigtay Sun Youyi, habka ma aha oo kaliya in ay bixiso suurtogalnimada diyaarinta qiimo jaban, graphene tayo sare leh, laakiin sidoo kale waxay bixisaa fikrad cusub oo loogu talagalay diyaarinta qalabka kale ee nanosheet laba-geesoodka ah.
