“…One of the first examples of this type of coating was made of positive alumina-coated silica (10 nm) and negative silica nanoparticles (10 or 40 nm): this structure turned out to improve the flame-retardant features of cotton or polyester fabrics [80,81]. More specifically, the fully inorganic coatings were able to prevent the melt-dripping phenomena of polyester during vertical flame spread tests and to significantly improve the time to ignition in cone calorimetry experiments.…”

Fabric flammability is a surface-confined phenomenon: in fact, the fabric surface represents the most critical region, through which the mass and heat transfers, responsible for fueling the flame, are controlled and exchanged with the surroundings. More specifically, the heat the fabric surface is exposed to is transferred to the bulk, from which volatile products of thermal degradation diffuse toward the surface and the gas phase, hence feeding the flame. As a consequence, the chemical and physical characteristics of the fabric surface considerably affect the ignition and combustion processes, as the surface influences the flux of combustible volatile products toward the gas phase. In this context, it is possible to significantly modify (and improve) the fire performance of textile materials by "simply" tailoring their surface: currently, one of the most effective approaches exploits the deposition of tailored coatings able to slow down the heat and mass transfer phenomena occurring during the fire stages. This paper reviews the current state of the art related to the design of inorganic, hybrid, or organic flame-retardant coatings suitable for the fire protection of different fabric substrates (particularly referring to cotton, polyester, and their blends). More specifically, the use of sol-gel and layer-by-layer (LbL) methods is thoroughly discussed; then, some recent examples of flame retardant coatings are presented, showing their potential advances and their current limitations.

“…Carosio's and Mannen's research groups applied nanoparticles of aluminosilicates and zirconium phosphate which, deposited on synthetic fibres, completely or almost utterly diminished dropping of polymer melt [34][35][36][37][38]. Regardless of the kind of substrate, most of the modifications minimized heat and gas products release during pyrolysis and combustion.…”

In this work, layer-by-layer assembly technique has been employed to deposit cationic chitosan (CH) and anionic montmorillonite (MMT-Na ? ) polyelectrolyte coatings on polyamide 6 (PA6). Without an additional surface treatment, 5, 10 and 20 bilayers of CH/MMT-Na ? were successfully adsorbed on PA6 matrix as confirmed by XRD, ATR-FTIR and SEM-EDX results. The thermal stability was evaluated using TGA and DSC methods, and it was found that neat PA6 demonstrated better performance (by ca. 5°C) and bilayers caused slightly delayed melting of PA6 crystalline phase. Some interesting results proving imparted flame retardancy by applied assemblies were obtained by vertical (VFT) and horizontal (HFT) flammability tests and microcalorimetric analysis (MCC) methods. It was found that all of the coated PA6 specimens have accomplished V-0 notes in VFT and the intensity of melt dripping reduced. According to MCC results, PA6 covered with 20 bilayers showed the highest reduction-up to 10% relative to reference material-in PHRR.
