Abstract

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.

壳聚糖的功能化及其在阻燃剂中的应用综述。

近年来，生物基阻燃剂作为可持续替代品受到了广泛关注，在阻燃方面取得了重要突破，成为未来发展的重点。壳聚糖（CS）源于生物质，在高级功能材料领域得到了广泛的应用。然而，在阻燃领域，壳聚糖单独表现出有限的效果，这促使研究人员探索其反应官能团，以制备多功能阻燃壳聚糖复合材料（FRCC）。本文综述了FRCC的改性，重点介绍了物理和化学技术如何基于燃烧机制增强阻燃性。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，解决了不同环境下的操作要求，并讨论了关键挑战。本研究为研究人员提供了FRCC的全面概述，为正在进行的研究和开发提供了宝贵的资源。

期刊介绍： The International Journal of Biological Macromolecules is a well-established international journal dedicated to research on the chemical and biological aspects of natural macromolecules. Focusing on proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids, the journal presents the latest findings in molecular structure, properties, biological activities, interactions, modifications, and functional properties. Papers must offer new and novel insights, encompassing related model systems, structural conformational studies, theoretical developments, and analytical techniques. Each paper is required to primarily focus on at least one named biological macromolecule, reflected in the title, abstract, and text.
