“…Ammonium PA (APA) synthesized from urea and PA afforded excellent flame retarded materials 24,67 . The formation of P‐O‐C covalent bonding with OH bearing materials makes ammonium PA favorable for flame retarding different materials (e.g., cellulose‐based materials) 24,67 . For example, it was reported that pHHR drastically reduced from 198.1 to 10.7 kW/m 2 , and CO/CO 2 production significantly decreased from 86.16 to 3.05 24 .…”

The article reviews the different methods of which, phytic acid (PA) can be employed as a flame retardant (FR) filler for different polymeric materials. The methods are critically discussed, based on the available literature and patents. Depending on the method used and the addition of FRs into a PA flame retarded system, different flame retarding modes of action and fire resistance performances are attained. The mechanism of action for PA‐based system remains similar to those observed in other phosphorus‐based FRs, namely, condensed and gas‐phase mechanisms.

Cotton fabric is widely used in many occasions, but it is flammable with high fire risk. To meet the great fire safety demands of cotton fabric, a novel lignocellulosic-based P-N synergistic (LFPN) flame-retardant coating with high efficiency and environment friendly was developed via mechanochemistry strategy in the aqueous phase. The characterisation results showed the stable P-O-C bond formed to bind both lignocellulosic fibre and ammonium polyphosphate (APP). Meanwhile, LFPN has an excellent dispersion in water with a nanometer-scale enveloping rod structure. The cotton fabric treated by the LFPN coating showed outstanding flame-retardant properties, the peak heat release rate (PHRR) was reduced by 77% and the residue mass was increased by 259% compared with control cotton fabric. And there was a self-extinction phenomenon during the flammability test of flame retardant cotton. Based on the analysis of the combustion and pyrolysis process, a gas-condensed two-phase flame retardant mechanism model was proposed, which could be used to explain the action process of LFPN for cotton fabric during combustion.

Flame-retardant materials with superwettability have received broad attention and research in the field of oil-water separation in recent years. However, it remains big challenging to fabricate flame-retardant and superwettable materials in terms of the complexity and environmental performance. Herein, a non-fluorinated coating containing flame retardants phytic acid/3-aminopropyltriethoxysilane and silica micronparticle/hexadecyltrimethoxysilane was developed. The performance of the coated samples is evaluated by thermogravimetric analysis, limiting oxygen index (LOI), cone calorimetry, and, water contact angle tests. The percentage of residue at 800 C for coated samples (cotton fabric, absorbent cotton, filter paper, cottonwood, packing cardboard) was reduced by 47.6%, 42.2%, 45.5%, 53.2%, and 50.8%, respectively. However, their control samples reduced by 87.4%, 84.6%, 88.4%, 77.2%, and 72.2%, respectively, under the same conditions. The percentage of residue at 800 C for coated samples is much higher than that of the pristine samples. The coated cotton fabric showed excellent flame retardant and superhydrophobic properties. Specifically, the coated cotton fabrics exhibited self-extinguishing properties in the flame burning tests, and the LOI increased significantly from 17.7% to 50.8%. Furthermore, the peak heat release rate and the total heat release values of the coated cotton fabric were significantly declined by 83.4% and 83.6% compared to untreated cotton fabrics, respectively. Additionally, due to its super-hydrophobic surface, the coated cotton fabric exhibited super-strong self-cleaning ability and waterproof performance. The coated cotton fabrics also showed good organic solvent/oil and water separation capabilities while reducing the risk of fire.
