습식산화된 CVD 그래핀에서의 산화아연 나노막대 직접성장 방법에 관한 연구

초록

In this study, the surface properties of graphene based on wet oxidation duration and examined the formation of ZnO nanorods on oxidized graphene without a seed layer. Raman spectroscopy and XPS examination demonstrated that with prolonged oxidation time, there was a corresponding increase in surface defects and oxygen functional groups (epoxy, hydroxyl, and carboxyl). A substantial rise in oxygen functional groups was noted during 60 minutes of oxidation, signifying the advancement of oxidation. ZnO nanorods were synthesized on oxidized graphene using a hydrothermal technique, resulting in an increase in diameter and a drop in length as the oxidation duration extended. This study illustrates that ZnO nanorods can proliferate on oxidized graphene without a seed layer and elucidates the correlation between the conditions of graphene oxidation and the growth of ZnO nanostructures.
