Influence of halloysite nanotubes onto the fire properties of polymer based composites: A review

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