Abstract

Graphene-based nanocomposite coatings have emerged as a promising solution for flame-retardant applications in industrial sectors due to their exceptional thermal stability, high surface area, and superior barrier properties. These coatings enhance fire resistance by creating protective char layers, reducing heat release rates, and limiting the spread of flames. Recent innovations focus on incorporating graphene with polymers, metal oxides, and other nanomaterials to achieve synergistic flame-retardant effects, while also improving mechanical strength, thermal conductivity, and environmental sustainability. Advanced fabrication techniques—such as solution blending, layer-by-layer (LBL) assembly, plasma-assisted deposition, and 3D printing—enable effective integration and precise control over coating structure and performance. Among these, solution blending stands out for its simplicity, scalability, and ability to ensure uniform dispersion of graphene within polymer matrices. Moreover, the integration of graphene-based coatings with smart sensing technologies allows real-time monitoring of thermal degradation, enhancing safety in critical industrial applications such as aerospace, construction, and manufacturing. This review highlights the latest advancements in graphene-enhanced flame-retardant coatings, discussing their mechanisms, fabrication strategies, and industrial potential. Future research directions should focus on cost-effective large-scale production, environmental impact assessment, and multifunctional applications to optimize fire protection in modern industries.

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
