GO can degrade or detach from the substrate over time, compromising the protective barrier. Developing strategies to enhance the adhesion and durability of GO coatings is crucial for their practical implementation.

The scalability of GO production and coating processes presents a significant hurdle for industrial adoption. Current methods for producing high-quality GO are often limited to laboratory scales, and scaling up these processes while maintaining consistent quality and cost-effectiveness is challenging. Similarly, applying GO coatings uniformly and efficiently on large or complex surfaces requires further technological advancements.

Compatibility issues between GO and various substrate materials pose another challenge. Different metals and alloys may interact differently with GO, affecting adhesion and overall performance. Developing universal GO-based solutions that work effectively across a wide range of substrates is an ongoing area of research.

Environmental concerns and regulatory compliance also present challenges. While GO itself is considered relatively environmentally friendly, the production processes and potential long-term environmental impacts of GO-based coatings need thorough investigation. Ensuring that these coatings meet stringent environmental regulations without compromising performance is a delicate balance to achieve.

Lastly, the cost-effectiveness of GO-based anti-corrosion solutions compared to traditional methods remains a significant barrier to widespread adoption. While the potential benefits are clear, the current production costs and application processes of GO coatings often outweigh those of conventional anti-corrosion treatments. Bridging this economic gap is crucial for the commercial viability of GO-based anti-corrosion technologies.

The anti-corrosion properties enhancement using graphene oxide (GO) is an emerging field in materials science, currently in its growth phase.
