Background:

• Graphene oxide (GO) is derived from graphite via chemical exfoliation, introducing oxygen functional groups.
• These functional groups impart unique properties to GO, influencing its behavior in thin films.
• GO's solubility in various solvents facilitates large-area thin-film deposition.

Purpose of the Study:

• To review the fundamental structure and properties of graphene oxide (GO) thin films.
• To discuss the relationship between GO's chemical and atomic structure and its properties.
• To explore the potential applications of GO-based thin films in electronics and optoelectronics.

Main Methods:

• Review of existing literature on graphene oxide synthesis and characterization.
• Analysis of structure-property relationships in GO thin films.
• Discussion of fabrication techniques for GO thin films.

Main Results:

• Graphene oxide (GO) thin films exhibit tunable electrical and optical properties.
• Properties are strongly dependent on chemical structure and can be modified via chemical engineering.
• Large-area thin-film fabrication is achievable due to GO's solubility.

Conclusions:

• Graphene oxide (GO) thin films are promising materials for next-generation electronics and optoelectronics.
• Understanding and controlling GO's structure is key to optimizing its performance.
• Further research into chemical engineering of GO can unlock its full potential in device applications.
