“…FTIR characterization of the samples resulted in identification and confirmation of chemical species, which resulted improved flame retardancy. Similarly, a new peak at 1720 cm −1 was observed due to C=O group as reported in previous literature [48]. This effect was not observed with the COT, COT-1 (A.W), COT-2 (A.W), or COT-3 (A.W) samples.…”

“…The peak of ZnO was perceived at 456 cm −1 in the FTIR spectra. Thus, SiO2 and ZnO have increased the flame retardancy [48][49]. Figure 2b has shown the FTIR (ATR) results of PC, PC-1 (B.W and A.W), PC-2 (B.W and A.W), and PC-3 (B.W and A.W).…”

“…Untreated COT was completely degraded at 600 • C in a nitrogen supply. Generally, COT decomposes in three stages: volatilization, main degradation, and carbonization [48]. The first stage started (300-400 • C) involves the conversion of COT into aliphatic char and volatile products.…”

In recent years, the use of functional textiles has attained attention due to their advantageous health and safety issues. Therefore, this study investigated the flame retardancy on cotton (COT) and polyester-cotton (PC) fabrics treated with different concentrations of silica and zinc nanoparticles through a sol-gel finishing technique. FTIR, SEM, and TGA were conducted for the characterization of coated fabric samples. The FTIR and SEM of Pristine and Treated Cotton and PC fabrics illustrated that the SiO2 (silica dioxide) and ZnO (Zinc oxide) nanoparticles were homogeneously attached to the fiber surface, which contributed to the enhancement of the thermal stability. The starting thermal degradation improved from 320 to 350 °C and maximum degradation was observed from 400 to 428 °C for the COT-2 cotton substrate. However, the initial thermal degradation improved from 310 to 319 °C and the highest degradation from 500 to 524 °C for the PC substrate PC-2. The outcomes revealed that the silica has a greater influence on the thermal properties of COT and PC fabric samples. Additionally, the tensile strength and flexural rigidity of the treated samples were improved with an insignificant decrease in air permeability.

“…− and BF 4 − anions were found to be much better compared to the other anions such as Cl − , CH 3 COO − , and (CF 3 SO 2 ) 2 N − . 24 Mostovoi et al 25 developed new compositions for fireproof foamed epoxy polymers using ammonium polyphosphate and ATFB. As a result, the after flame time of epoxy foam becomes shorter and mass losses when flaming in the air are reduced significantly.…”

In this study, a novel flame retardant ammonium tetrafluoroborate (ATFB) was successfully synthesized using boric acid (H 3 BO 3) and ammonium hydrogen difluoride (NH 4 HF 2) as the reactants. In addition to ATFB, aluminum hydroxide (Al(OH) 3) was used as a flame retardant and red mud (RM) waste was used as a filler to prepare epoxy composite materials with enhanced flammability properties. The appropriate ratio of RM:ATFB:Al(OH) 3 both in terms of combustion and mechanical properties was found to be 15:10:5 wt%. The tensile strength of the composite in this ratio was obtained as 112 MPa, while the neat ER was 46 MPa. The burnout of the composite with the appropriate RM:ATFB:Al(OH) 3 ratio decreased in the first 10 seconds, and extinguished in 32 seconds. Moreover, the burned area of this composite was the smallest among all the others. The experimental and estimated LOI values for this composite was found as 26 and 29, respectively.

“…23 The sol-gel method is a technique that can be used to trap molecules, such as fluorophore, in a 2D or 3D silica-based system, and is a technique well known for its low-temperature conditions and its ability to achieve different shapes. [24][25][26][27][28] This process requires hydro-alcoholic solutions of an organometallic precursor, whereby most of the time a hybrid film is coated onto the textile surface to confer it new functionalities, depending on the entrapped molecules, such as flame retardancy, 29 water repellency, 30 or antimicrobial. 31,32 Besides, when a chromic dye is incorporated inside the sol-gel coating, the surface of the textile materials can be used as a pH probe, which leads to flexible sensors that offer the possibility for continuously controlling the pH of large volume systems.…”
