MODİFİYE HUMMERS YÖNTEMİYLE GRAFEN OKSİT (GO) SENTEZİ VE KARAKTERİZASYONU

Öz

ÖZET

Bu çalışmada modifiye Hummers yöntemi kullanılarak grafitten grafen oksit (GO) sentezlenmiştir. Literatürde bilinen diğer yöntemlere göre modifiye Hummers yöntemi; işlem basamakları açısından daha basit ve düşük maliyetlidir. Ayrıca Hummers yöntemine göre daha tehlikesiz ve daha çevre dostu bir yöntemdir. SEM görüntülerinde katmanlı ve çok ince GO yapıları gözlenmiştir. EDX/SEM Elementel analizde oksijen (O) oranının yaklaşık %23,60 olması oksidasyon işleminin gerçekleştiğini göstermektedir. GO yapısının termal kararlılığı TGA analizinden anlaşılmaktadır. XRD analizinde 2θ piki, 10,5524° de elde edilmiştir. Ayrıca, FT-IR spektroskopisi ve Raman spektroskopisinde ise GO’e ait karakteristik pikler görülmüştür. Elde edilen sonuçlardan modifiye Hummers yöntemi ile grafit tozundan başarılı bir şekilde GO sentezlendiği anlaşılmaktadır.
