Fire retardancy is of crucial importance for most of the polymer applications and fire proofing materials are often based on polymer blends with high fire retardants contents (up to 60wt%) which induce cost increase and lower mechanical performances. The use of ammonium polyphosphate (APP) as fire retardant allows maintaining good mechanical properties but it can be removed from the polymer matrix under hygrothermal conditions. In this context, halloysite nanotubes (HNTs) offer a good alternative as carriers of flame retardant systems to control the migration of the flame retardant molecules encapsulated in the HNT lumen for long-term aging properties. This review highlights the influence of the presence of HNTs and its derivatives on the fire retardancy performances of polymer-based composites. The discussion is examined according to the nature of the polymer from thermoplastics to thermosets.

阻燃性对于大多数聚合物应用至关重要，并且防火材料通常基于具有高阻燃剂含量（最高60wt％）的聚合物共混物，这会导致成本增加和机械性能降低。使用聚磷酸铵（APP）作为阻燃剂可保持良好的机械性能，但可在湿热条件下将其从聚合物基质中除去。在这种情况下，埃洛石纳米管（HNT）提供了很好的替代品，作为阻燃剂系统的载体，以控制封装在HNT内腔中的阻燃剂分子的迁移，以实现长期老化。这篇综述强调了HNTs及其衍生物的存在对聚合物基复合材料阻燃性能的影响。
