“…The first attempt has been made by depositing complex architectures made of chitosan, ammonium polyphosphate and silica nanoparticles bearing positive or negative charge on cotton-PET blends [101]. Such coating constituents have been selected on the basis of the results achieved by silica/silica coatings and chitosan/ ammonium polyphosphate coatings described in the previous paragraphs.…”

“…The first example of an LbL hybrid coating consisted of chitosan, ammonium polyphosphate, and silica nanoparticles (bearing positive or negative charges) deposited on cotton-PET blends [112]. It was found that the morphology and the physical stability of the assemblies play a key role in determining the fire performance of the treated substrates.…”

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.

“…34 Since then, researchers have developed LbL FR coatings for textiles, [34][35][36] plastic plaques, [37][38][39] and polyurethane foam (PUF) 40,41 . The coatings were constructed of synthetic and bio-based polymer binders (e.g., polyacrylic acid and DNA), 42 and have contained a wide range of fire retardants and protective residue formers (e.g., montmorillonite clay, 16,33,34 silica, [43][44][45] α-M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT zirconium phosphate, 46 and carbon nanotubes and nanofibers [47][48][49].…”
