Summary: This review focuses on the applications of polyphthalamide (PPA) in the automotive industry and other industries. The properties and research progress of PPA and its blends, as well as PPA composites, are discussed. PPA is widely used in various fields due to its excellent chemical resistance, high strength, stiffness at high temperature, and dimensional stability. Moreover, there are still many unexplored research opportunities, particularly in electric vehicle and aerospace applications.

Summary: Intumescent flame retardant (IFR) is an environmentally friendly flame retardant that has improved water solubility, making it suitable for use in cellulose-based textiles. By treating cotton fabrics with a water-soluble carbon-nitrogen-phosphorus (C-N-P) ternary IFR called PTETP, the flame retardant performance and thermal stability of the fabrics are significantly enhanced without compromising their tensile strength.

Summary: The novel microcapsule flame retardant MAHP significantly improves the flame retardancy and heat resistance of EP matrix, with a large amount of residue in TG tests. The addition of MAHP also results in a dense and continuous carbon layer in char residues, while retaining the mechanical properties of the material.

Summary: The synthesized PASO can effectively improve the flame retardancy of polycarbonate while maintaining its mechanical performances, achieving UL 94V-0 rating and high limited oxygen index value when loaded with 1 wt% PASO and 5 wt% talc as anti-dripping agent. Analysis showed that PASO exhibited flame retardant mechanism in both gas and condensed phases.

Summary: The aim of this research was to design a dual-exterior surface chemical modification of eco-friendly layered double hydroxides (LDH-S@PA) to improve the dispersibility and flame retardancy in the polymer matrix. The study successfully prepared the target product with a hydrophobic surface and improved the thermal stability of LDH-S@PA. The addition of LDH-S@PA into biobased poly(trimethylene terephthalate) (PTT) significantly enhanced the dispersity and flame retardancy of the PTT, while also improving the mechanical properties of the composites. This facile approach holds promise for flame retardant formulations in future polymer applications.

Summary: Polyoxymethylene (POM) nanocomposites reinforced with synthetic wollastonite nanofibers (SWN) showed improved mechanical, thermal, and flammability properties as the aspect ratio of SWN increased. Higher aspect ratio SWN resulted in increased tensile strength, Young's modulus, and impact strength in POM nanocomposites. However, lower aspect ratio SWN performed better in flame retardancy, with delayed time to ignition and decreased peak heat release rate.

Summary: A copolymer of alkali lignin and polyacrylamide was fabricated by graft copolymerization and chelated with Fe3+ to prepare flame-retarded PBS composites. The replacement of IFR by lignin chelate improved mechanical performance and flame retardancy. When the loading of IFR and lignin chelate were 24 and 1 wt%, significant improvements in LOI value, char residue mass, and thermal properties were observed.

Summary: This study investigated the effect of different concentrations of an intumescent formulation and montmorillonite on the fire behavior of polylactic acid composites. The results showed that the addition of the intumescent formulation and montmorillonite improved the fire-retardant performance of the composites, with the highest AP concentration (17%) and the lowest ANa concentration (1.2%) achieving the best result.
