“…They achieved fire retardancy; however, the tensile strength and handle-ability of the treated samples were reduced. In the review of literature data, a lot of studies have also described layer-by-layer techniques [34][35][36], green synthesis methods, and natural approaches [9] for thermal stability and FR performances; however, due to the involvement of high cost of technology and loss of deposited minerals during repeated washings, the FRs predicament has yet to be resolved [37]. Recently, organosilicon derivatives (silanes and polysiloxanes) have been applied to cotton fabrics for high FR efficiencies and protection coatings [38].…”

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.

“…Composite materials with natural cellulosic fibers had attracted a lot of attention due to their biodegradability, excellent mechanical properties, and high surface reactivity. Cotton is one of the most abundant cellulosic fibers and it is widely used in industry and research settings due to its flexibility, comfortability, water absorption, air permeability, and low cost . The functionalization of cotton with inorganic nanoparticles such as silver, zinc oxide, titanium dioxide, silica, and magnetite has rendered a myriad of composite materials in order to incorporate unique magnetic, supercapacitor, UV protection, self‐cleaning, antibacterial/antimicrobial, photocatalysts, fire retardant, and drug loading and delivery properties with extensive applications in medical, construction, automotive and smart materials fields …”

Magnetite (Fe3O4) and magnetic core‐shell mesoporous silica (Fe3O4‐mSiO2) nanoparticles are employed to coat cotton fibers using a room temperature water‐based direct electrostatic assembly method with polyelectrolytes. Core‐shell nanoparticles are fabricated by coating super‐paramagnetic magnetite clusters with a mesoporous silica layer (mSiO2) using a surfactant‐templating approach. The Fe3O4 clusters are initially synthesized by a co‐precipitation process. The cotton fibers are modified through a layer‐by‐layer technique using dipping cycles with PDDA and PSS polyelectrolytes solutions to enable further nanoparticles attachment. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) images provides morphologic information of the synthesized nanoparticles and the modified cotton fibers. Composition and physicochemical properties are studied by powder XRD, FTIR, and SEM‐EDX methods, and thermogravimetric analysis (TGA) are carried out to determine the amount of nanoparticles adsorbed onto cotton samples. The saturation magnetization (MS) of nanoparticles determined by a vibrating sample magnetometer (VSM) is greater than that of the cotton‐nanoparticles nano‐composites. Potential applications of these composite materials can include protective clothing and transdermal drug delivery systems.

“…Changes in the degradation curve can be observed from Figure 4 and Table 1. The weakest C–NH chain of pristine PU caused degradation of hard segments of PU, which led to the formation of isocyanates, –OH functional groups, –NH functional groups, and carbon dioxide [23]. The temperature was 302 °C when weight loss was 10% (T d10 ).…”

The NCO functional group of 3-isocyanatoproplytriethoxysilane (IPTS) and the OH functional group of 10-(2,5-dihydroxyphenyl)-10H-9-oxa-10-phospha-phenantbrene-10-oxide (DOPO-BQ) were used to conduct an addition reaction. Following completion of the reaction, triglycidyl isocyanurate (TGIC) was introduced to conduct a ring-opening reaction. Subsequently, a sol–gel method was used to initiate a hydrolysis–condensation reaction on TGIC–IPTS–DOPO-BQ to form a hyperbranched nitrogen–phosphorous–silicon (HBNPSi) flame retardant. This flame retardant was incorporated into a polyurethane (PU) matrix to prepare a hybrid material. Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), limiting oxygen index (LOI), UV-VIS spectrophotometry, and Raman analysis were conducted to characterize the structure and analyze the transparency, thermal stability, flame retardancy, and residual char to understand the flame retardant mechanism of the prepared hybrid material. After the flame retardant was added, the maximum degradation rate decreased from −36 to −17 wt.%/min, the integral procedural decomposition temperature (IPDT) increased from 348 to 488 °C, and the char yield increased from 0.7 to 8.1 wt.%. The aforementioned results verified that the thermal stability of PU can be improved after adding HBNPSi. The LOI analysis indicated that the pristine PU was flammable because the LOI of pristine PU was only 19. When the content of added HBNPSi was 40%, the LOI value was 26; thus the PU hybrid became nonflammable.
