During the last decade, the utilization of chitin, and in par0ticular its deacetylated form, i.e., chitosan, for flame retardant purposes, has represented quite a novel and interesting application, very far from the established uses of this bio-sourced material. In this context, chitosan is a carbon source that can be successfully exploited, often in combination with intumescent products, in order to provide different polymer systems (namely, bulky materials, fabrics and foams) with high flame retardant (FR) features. Besides, this specific use of chitosan in flame retardance is well suited to a green and sustainable approach. This review aims to summarize the recent advances concerning the utilization of chitosan as a key component in the design of efficient flame retardant systems for different polymeric materials.
在过去的十年中，壳聚糖的应用，特别是其脱乙酰化形式，即壳聚糖，在阻燃方面的应用，代表了一种非常新颖和有趣的应用，与这种生物来源材料的既定用途相去甚远。在这种情况下，壳聚糖是一种碳源，可以与膨胀型产品成功结合，为不同的聚合物系统（即块状材料、织物和泡沫）提供高阻燃（FR）性能。此外，壳聚糖在阻燃方面的这种特殊用途非常适合绿色和可持续的方法。本综述旨在总结壳聚糖作为设计不同聚合物材料高效阻燃体系的关键组成部分的最新进展。
