Description
Summary:Thermoplastic resins are indispensable materials in various applications, including automotive, electronics, packaging, and construction, owing to their superior mechanical strength, ease of processing, and versatility. However, their inherent flammability poses a significant challenge to fire safety, limiting their broader use in environments demanding stringent flame-retardant performance. MXenes, a newly emerging class of two-dimensional (2D) nanomaterials, have recently attracted significant attention for their application in flame-retardant polymer composites because of their multilayered structure and exceptional versatility. This review comprehensively explores the state-of-the-art advancements in flame-retardant thermoplastic resins, focusing on the use of MXenes and MXene-based materials to meet high-performance requirements, including mechanical strength, thermal stability, flame retardancy, electromagnetic interference (EMI) properties, and multifunctionality. Furthermore, the modification approaches of MXene-based flame retardants, the preparation of MXene-based thermoplastic resin composites, and the mechanisms of action for different matrices are also discussed in this review. Finally, this review discusses the challenges and potential developments for MXene-based thermoplastic composites, offering insights into the practical applications and growing demands for flame-retardant materials.
