Progress in the functional modification of graphene/graphene oxide: a review

Abstract

Graphene and graphene oxide have attracted tremendous interest over the past decade due to their unique and excellent electronic, optical, mechanical, and chemical properties.

Sample Preparation Using Graphene-Oxide-Derived Nanomaterials for the Extraction of Metals

“…In this approach, the structure and excellent properties of graphene oxide are maintained, while its dispersibility and stability are improved. Finally, element doping modifications are performed to incorporate different elements into the sorbent and thus enhance the overall performance of the material [58,59].…”

Investigation of Properties of Graphene Reinforced Epoxy Nanocomposites

“…Bu nedenle, literatürde, grafenin yukarıda sayılan üstün özelliklerinden dolayı epoksi matrisi içerisine katılması ile ilgili çok fazla deneysel çalışma bulunmaktayken [17][18][19][20][21][22][23][24][25][26], bu çalışmaların bir kısmı, grafenin yüzeyinin modifiye edilmesi ile grafen ve epoksi arasındaki ara yüzey enerjisininin arttırılmasını ve daha homojen karışımların hazırlanmasını sağlamaya yöneliktir [27]. Kovalent bağlar ile fonksiyonelleştirme, kovalent olmayan fonksiyonelleştirme ve elementel doplama fonksiyonelleştirmede kullanılan temel yöntemlerdir [28]. Duan ve ark., benzil glisidil eterini (BGE) grafen yüzeyini modifiye etmekte kullanmışlardır.…”

Recent advances in graphene-based materials for dye-sensitized solar cell fabrication

“…As a result, the derivatives of graphene, such as graphene oxide (GO), which is an oxygen functionalized graphene sheet, and reduced graphene oxide (rGO), have been widely explored owing to their high solubility in organic solvents, which makes them compatible with the lowcost, facile, and large-scale solution synthesis. 28 Although GO exhibits an insulating character, the chemical or thermal reduction of GO to remove the oxygen functional groups helps restore electron delocalization, enhancing carrier transport, and thereby converting the electrically insulating GO into conducting graphene sheets. [29][30][31] Among the graphene synthesis routes, the reduction of GO and CVD, are the most commonly used approaches due to their capability for large-scale synthesis.…”
