“…The recognized characteristic bands of phytic acid viz., O-P-O vibration band that appears at 1639 cm − 1 , and CH 2 stretching vibration band at 2844 cm − 1 , and the P-OH vibration was at 2820 cm − 1 [34]. Moreover, bands at 1091 and 975 cm − 1 which are assigned to asymmetric and symmetric stretching vibrations of P-O-C [35].The disappearance of some bands in the FTIR spectra of HPP/Keratin and HPPBTCA/sericin as compared to PA, such as those at 2820 and 1247 cm -1 , proved that there is a chemical reaction that has taken place between PA and PE (structure 1) as well as PE and BTCA (structure 3).…”

A synergy of phytic acid (PA) and proteinic biopolymer, namely keratin and sericin, was adopted to boost the resistance to flame, ultraviolet rays, and electrostatic charges, as well as enhance hydrophilicity of acrylic fabric. An efficient flame retardant (FR) was synthesized by reacting calculated amounts of PA and pentaerythritol (PE) to form hexa-pentaerythritol phytate ester (HPP), which in turn reacted with a proteinic bioplymer in the presence or absence of a crosslinking agent to produce a multifunctional FR formulation. The prepared formulation was utilized as a multifunctional textile auxiliary for improving the resistance of alkali-hydrolyzed acrylic fabric to flame and UV rays and for enhancing its hydrophilic and anti-static properties. The solubility of the prepared formulation in different solvents at different temperatures was examined. The chemical structure of the synthesized functional FR was investigated using FTIR and by determining its phosphorus, nitrogen, and carboxylic contents. The mechanism of reaction between the synthesized FR and the hydrolyzed fabric was proposed. The discrepancy between the topography of the treated and untreated fabrics was monitored using scanning electron microscopy. The results revealed that the treated acrylic fabric exhibited a durable and superior resistance to flame, which was not adversely affected by washing up to 20 times. The anti-static property and wettability of the treated fabrics were highly improved, whereas their resistance to the deteriorative action of UV rays was enhanced to an almost adequate level. The proposed process is an additive method for improving some performance and comfort attributes of acrylic fabric without causing severe loss in the fabric’s strength.

“…Due to the ammability of ENR and PLA, it is an urgent challenge to improve their ame retardancy [15,16]. At present, the main strategy to improve the ame retardancy of polymers is to add ame retardants to the matrix, such as halogen additives [17,18], metal hydroxides [19,20], silicon compound ame retardants [21,22], intumescent ame retardants (IFRs) [23][24][25]. As far as these ame retardants are concerned, IFRs have received widespread attention because of their low smoke[26], low toxicity [27], high e ciency[28] and small addition [23].…”

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).

“…In the 1980s, European countries and the United States of America discussed the toxicity and environmental issues posed by halogenated flame retardants, which promoted research on new flame retardants. The goals of low toxicity, halogen-free, and synergistic compounding have become the focus of flame-retardant research [5].…”

Epoxy resins (EPs) require the addition of flame retardants to extend their application scope. High-efficiency flame retardants typically contain halogens, which can cause tremendous harm to humans and the environment. In this study, we investigated the syntheses of new phosphorus–nitrogen flame retardants (DIT) and flame-retardant EP. DIT is composed of 6-(2,5-dihydroxyphenyl) dibenzo[c,e][1,2]oxaphosphinine 6-oxide, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, and tris-(2-hydroxyethyl) isocyanurate. DIT chemical structure was analysed by Fourier-transform infrared spectroscopy. Several formulations of modified epoxy resins (DIT-EPs) were obtained by adding different quantities of DITs. We found that when the flame retardant content reached 25%, the limiting oxygen index of the DIT-EP was 29.0%. This finding expands the application range of EPs.
