Graphene oxide (GO) is a promising material with diverse applications in electronics, energy storage, desalination, and medicine. However, its instability leads to challenges in product management. This study identifies three distinct GO states—stable intrinsic GO (iGO), metastable GO (mGO), and transient GO (tGO)—using UV-Vis absorption spectra and other analytical techniques. The iGO state is stable for only 5 days at 298 K, but can be stabilized by storing at low temperatures or adding ammonium peroxydisulfate. The mGO state is characterized by a blue shift in the π-π* transition, while the tGO state transforms into reduced graphene oxide (rGO). The study reveals that GO undergoes structural and chemical changes during ripening, including the decomposition of epoxy groups, changes in oxygen functional groups, and alterations in interlayer distances. These changes affect the optical, magnetic, and electrical properties of GO. The research highlights the importance of understanding GO's instability for its application in various fields. The findings suggest that controlling ripening conditions can help stabilize GO and improve its performance in devices. The study provides insights into the structural evolution of GO and offers strategies for its long-term stability.Graphene oxide (GO) is a promising material with diverse applications in electronics, energy storage, desalination, and medicine.
