“…Superhydrophobic, superoleophobic, and other surfaces of extreme wetting properties have attracted the interest of many researchers owing to their wide range of potential applications [1,2]. Superhydrophobicity is usually achieved by developing a special hierarchical micrometer and nanometer sized structure [3] on the surface of interest and applying low surface energy agents [4].…”

A method to produce multifunctional coatings for the protection of silk is developed. Aqueous dispersion, free of any organic solvent, containing alkoxy silanes, organic fluoropolymer, silane quaternary ammonium salt, and silica nanoparticles (7 nm in mean diameter) is sprayed onto silk which obtains (i) superhydrophobic and superoleophobic properties, as evidenced by the high contact angles (>150 •) of water and oil drops and (ii) antimicrobial properties. Potato dextrose agar is used as culture medium for the growth of microorganisms. The protective coating hinders the microbial growth on coated silk which remains almost free of contamination after extensive exposure to the microorganisms. Furthermore, the multifunctional coating induces a moderate reduction in vapor permeability of the treated silk, it shows very good durability against abrasion and has a minor visual effect on the aesthetic appearance of silk. The distinctive roles of the silica nanoparticles and the antimicrobial agent on the aforementioned properties of the coating are investigated. Silica nanoparticles induce surface structures at the micro/nano-meter scale and are therefore responsible for the achieved extreme wetting properties that promote the antimicrobial activity. The latter is further enhanced by adding the silane quaternary ammonium salt in the composition of the protective coating.

“…The same group [106] proposed a polyhexamethylene guanidine phosphate-ammonium polyphosphate LbL assembly for providing cotton fabric with flame-retardant and antimicrobial properties. Vertical flame spread tests demonstrated that the deposited LbL coating was able to reduce the burning time, suppress the afterglow, and increase the residue, while keeping intact the textile structure.…”

Surface-Engineered Fire Protective Coatings for Fabrics through Sol-Gel and Layer-by-Layer Methods: An Overview

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.

“…Electrostatic layer‐by‐layer (LbL) assembly is used as a common technique for cotton modification through the formation of controllable nanolayers on the surface by the adsorption of oppositely charged polyelectrolytes . LbL technique is attractive due to its simplicity and easy incorporation, besides, the solutions employed during this technique can be reused in which water is the main solvent . Methods like dip‐coating and padding allow the formation of eletrostatic nanolayers controlled by assembly cycles that tailor onto the morphology of the cotton fiber surface, resulting in an electrostatic interaction between the negative charges of nanoparticles and the polyelectrolytes of the cotton surface …”

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.
