In recent years, bio-based flame retardants have gained significant attention as sustainable alternatives, achieving important breakthroughs in flame retardancy and becoming a key focus for future development. Derived from biomass, chitosan (CS) has been widely used in the field of advanced functional materials. However, in the field of flame retardancy, chitosan alone shows limited effectiveness, leading researchers to explore its reactive functional groups for creating multifunctional flame retardant chitosan composites (FRCC). This review examines FRCC modifications, focusing on how physical and chemical techniques enhance flame retardancy based on combustion mechanisms. Particular emphasis is placed on the impact of embedding flame-retardant elements. Additionally, this paper outlines FRCC performance characteristics, addressing operational requirements in varied environments, and discusses key challenges. This study offers researchers a comprehensive overview of FRCC, serving as a valuable resource for ongoing research and development.
近年来，生物基阻燃剂作为可持续替代品受到了广泛关注，在阻燃性方面取得了重要突破，成为未来发展的关键焦点。壳聚糖（CS）来源于生物质，已广泛应用于先进功能材料领域。然而，在阻燃领域，单独的壳聚糖显示出有限的有效性，这促使研究人员探索其反应性功能基团以制备多功能阻燃壳聚糖复合材料（FRCC）。本综述研究了FRCC的改性，重点关注物理和化学技术如何基于燃烧机理提高阻燃性。特别强调了嵌入阻燃元素的影响。此外，本文概述了FRCC的性能特点，讨论了其在不同环境中的使用要求，并探讨了关键挑战。本研究为研究人员提供了FRCC的全面概述，是正在进行的研发的宝贵资源。
