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.

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.
