Hybrid Carbon–Metal/Framework Materials (Graphene/MOF/COF) for Corrosion Protection and Electrochemical Stability

The global economic impact of metallic corrosion represents a significant challenge to industrial sustainability, with costs estimated to exceed USD 2.5 trillion annually, often surpassing three percent of the global gross domestic product. Traditional protective measures, primarily organic and chromate-based coatings, are increasingly scrutinized due to environmental toxicity and intrinsic structural limitations, such as micropores and chain-gap defects that facilitate the ingress of corrosive species like chloride ions and moisture. Graphene-based nanostructures have emerged as a revolutionary alternative, offering exceptional barrier properties and mechanical toughness. However, challenges regarding uniform dispersion and the "corrosion promotion effect" of pristine graphene have necessitated the development of hybrid architectures. By integrating graphene with Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs), researchers can leverage tunable porosity and active chemical sites for superior anticorrosion performance. This market for advanced graphene coatings is projected to excel in near future which is driven by demands in aerospace, automotive, and marine engineering for high-performance, multifunctional protective solutions.The primary objective of this Research Topic is to serve as a foundational reference and a strategic roadmap for the global scientific and industrial communities concerned with advanced corrosion mitigation. The topic aims to compile and synthesize the broader landscape of hybrid framework materials to assist readers in conducting precise corrosion assessments and designing optimized protective systems for modern infrastructure. Key objectives include:1. Providing a comprehensive and detailed review of the fundamentals of reticular chemistry as applied to corrosion science, establishing a robust theoretical base for researchers, engineers, and graduate students.2. Evaluating a diverse range of modern synthesis methodologies—including in-situ growth, solvothermal routes, and scalable fabrication techniques—to aid industry professionals in selecting optimal production pathways.3. Detailing the individual and synergistic effects of Graphene, Metal-Organic Frameworks (MOFs), and Covalent Organic Frameworks (COFs) on systemic Corrosion Protection and Electrochemical Stability, exploring how their integration enhances barrier impermeability, chemical robustness, and active inhibition.This Research Topic welcomes Original Research, Reviews, Mini Reviews and Perspectives on the following, but is not limited to, themes:• Novel synthesis strategies for robust graphene/MOF/COF hybrids, including in-situ growth, in-situ polycondensation, de novo framework design, chemical vapor deposition, and solvothermal routes• Advanced characterization techniques, including electrochemical impedance spectroscopy (EIS), molecular dynamics simulations, and operando spectroscopic methods for corrosion assessment• Mechanistic insights into the tortuous path effect and its role in enhancing barrier impermeability of hybrid coatings• Functional hybrid coatings with pH-responsive self-healing behavior enabled by encapsulated inhibitors within MOF or COF pores• Applications of graphene/MOF/COF hybrids in advanced energy storage systems, including supercapacitors, batteries, and electrocatalytic devices• Scalable fabrication pathways and techno-economic considerations for translating hybrid framework coatings from laboratory to industrial deployment• Recent advances in Hybrid Carbon–Metal/Framework Materials (Graphene/MOF/COF) Topic editors: Dr. Ashish Kumar, Saprizal Hadisaputra, Shveta Sharma Source: https://www.frontiersin.org/research-topics/81352/hybrid-carbon-metalframework-materials-graphenemofcof-for-corrosion-protection-and-electrochemical-stability
