Habka kiimikaad ayaa marka hore oksaydh ka dhigaya graphite graphite oxide by falcelinta oksaydhisku, oo waxay kordhisaa kala dheeraynta lakabka iyada oo la soo bandhigayo ogsijiin ka kooban kooxo shaqaynaysa atamka kaarboonka ee u dhexeeya lakabyada garaafka, taas oo wiiqaysa isdhexgalka ka dhexeeya lakabyada.

oksidation caadiga ah

Hababka waxaa ka mid ah habka Brodie, Habka Staudenmaier iyo Habka Hummers [40].Mabda'a ayaa ah in marka hore lagu daaweeyo graphite leh aashito xoog leh,

Ka dibna ku dar oksaydhiyaha xooggan ee oksaydheynta.

Garaafiga oksaydhka ah ayaa laga xayuubiyay ultrasonic si uu u sameeyo graphene oxide, ka dibna la yareeyo iyadoo lagu darayo wakiilka yaraynta si loo helo graphene.

Wakiilada yaraynta caadiga ah waxaa ka mid ah hydrazine hydrate, NaBH4 iyo yaraynta alkali ultrasonic xooggan.NaBH4 waa qaali waana sahlan tahay in lagu hayo curiyaha B,

In kasta oo yaraynta alkali alkali xoog waa mid fudud oo deegaanka saaxiibtinimo, way adag tahay in la yareeyo *, iyo tiro badan oo ah kooxaha functional oxygenated sii joogi doona ka dib markii la dhimay.

Sidaa darteed, hydrazine hydrate ka jaban ayaa badanaa loo isticmaalaa si loo yareeyo graphite oxide.Faa'iidada hoos u dhigista hydrazine hydrate waa in hydrazine hydrate uu leeyahay awood yareyn xoog leh oo ay fududahay in la beddelo, markaa ma jiri doonto wax wasakh ah oo ku hadhay alaabta.Habka dhimista, qadar ku habboon oo biyaha ammonia ah ayaa badanaa lagu daraa si loo hagaajiyo awoodda dhimista ee hydrazine hydrate,

Dhanka kale, waxay ka dhigi kartaa in dusha sare ee graphene ay iska celiyaan midba midka kale sababtoo ah eedeymaha taban, taas oo yareyneysa qulqulka graphene.

Diyaarinta miisaanka weyn ee graphene waxaa lagu xaqiijin karaa oksaydhka kiimikada iyo habka dhimista, iyo graphene oxide wax soo saarka dhexdhexaadka ah ayaa si fiican ugu firidhsan biyaha,

Way fududahay in wax laga beddelo oo la shaqeeyo graphene, sidaas darteed habkan waxaa badanaa loo isticmaalaa cilmi-baarista walxaha isku dhafan iyo kaydinta tamarta.Laakiin sababtoo ah oksaydheynta

Maqnaanshaha qaar ka mid ah atamka kaarboon ee habka ultrasonic iyo hadhaaga kooxaha functional oxygen-ka kooban ee geeddi-socodka dhimista inta badan ka dhigi graphene soo saaray ka kooban cillado dheeraad ah, taas oo yaraynaysaa ay conductivity, sidaas xaddidaya ay codsi ee berrinkii graphene leh shuruudaha tayada sare leh. .
