Research Progress in Flame-retardant Polyurethane Nanocomposites
Polyurethane has excellent physical and mechanical properties,and is widely used in leather,functional materials and medical fields.However,polyurethane is prone to combustion,so the introduction of nanomaterials with flame-retardant function in polyurethane is of great significance to improve the fire safety of polyurethane materials.This review first summarized the advantages of nanomaterials over traditional flame retardants.The development of flame-retardant polyurethane nanocomposites in terms of preparation,mechanism,and applications in leather and functional materials was demonstrated in this review.We also discussed the introduction of various types of nanomaterials,e.g.,carbon nanotubes,metal-organic frameworks,and MXene.Meanwhile,research and development direction of the flame-retardant polyurethane nanocomposites was discussed.
