“…Different types of flame retardants have different effects on the properties of PA based materials due to their varied flame-retardant mechanisms. However, the halogen-containing flame retardants are not friendly to the environment and have been banned in many countries [7]. Mu et al [8] have synthesized PA6/MCA by in situ polymerization.…”

Flame retardant polyamide 6 (PA6) composites (PA6/PTCDA) were prepared by in situ polymerization of caprolactam with adding 0.01-2.5 wt% perylene-3,4,9,10-tetracar-boxylic dianhydride (PTCDA). The structure and properties of PA6/PTCDA composites were studied by Fourier transform infrared spectroscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, thermal conductivity, and limiting oxygen index (LOI) measurements. The results indicated that the crystallization of the PA6 chains was suppressed with 2.5 wt% PTCDA, and the LOI of the composite was 29.5. At the same time, the addition of PTCDA made the composites form a coke layer in the process of combustion, protecting the flammable components from volatilization and enhanced the flame retardant performance of the composites. This indicated that the PA6/PTCDA composite prepared by in situ polymerization possessed good flame retardant properties.

With the rapid development of society, polymer materials are widely used in automotive, construction, and electronic components due to their excellent properties such as easy processing, cheap price, and corrosion resistance. However, most polymers, such as rubber and leather, suffer from poor mechanical properties, susceptibility to micro cracking and ammability. In this paper, an epoxidized natural rubber (ENR)/polylactic acid (PLA)/chitosan (CS)/guanidine phosphate (GP) composite with certain self-healing and ame-retardant properties was successfully prepared. The network structure is constructed by forming thermoplastic elastomers (TVPs) through ENR and PLA, and the amino groups on CS and GP can form hydrogen bonds with ENR. which improves the mechanical properties of ENR/PLA composites and gives the ENR/PLA/CS/GP composites excellent self-healing properties. Secondly, CS and GP can also form intumescent ame retardants to improve the ame-retardant properties of ENR/PLA composites. Among them, the ENR/PLA/CS 2 /GP 4 composite can achieve 78% self-healing effect and 35.8% reduction in ame retardant heat release rate (HRR).
