“…However, an experimental investigation conducted to find the impact of pH and temperature on average conductivity of copper-plated fabric [23,24]. After soaking the polyester fabrics into an acidic SnCl 2 bath, Sn 2 ? ions adsorb onto the particle surface, forming a uniform layer.…”

An experimental investigation was utilized to present the IR rejection performance of Cu-Ni-P-Ni composite double-layer electroless plated PET fabric compared to fabric samples composed of Cu-Ni-P metallic monolayer. Accordingly, the effect of a range of operational parameters was explored on the conductivity of electroless plated PET fabric. Results indicate higher conductivity and lower durability for Cu-Ni-P-coated samples compared to its counterpart with same sub-layer included with nickel on top layer. The SEM image of CuNi-P particle on PET fabric shows a hexagonal non-homogenous morphology with nanoscale crack on its surface. However, the micrograph of the Cu-Ni-P-Ni electroless plated fabric shows an extremely compact and continuous phase with clear boundaries containing semispherical particles. The thermopile radiated sensing system was used as a sophisticated device to show the thermal energy absorption level. The acquired data indicate a 2.3 and 2.7 unit reduction in transmitted radiated power, respectively, for Cu-Ni-P and Cu-Ni-P-Ni conducting fabric. The captured thermal camera images of human body while keeping in front of a Cu-Ni-P conducting fabric revealed a nearly black and blue feature which proves the significant decrease in body radiated thermal energy. However, the thermal image of Cu-Ni-P-Ni conductive fabric shows almost black appearance in all areas. It can be presumably due to improving of the IR rejection performance and also formation of a massive barrier against body thermal radiation for promising camouflage applications.

“…Deposition of metallic layers on fabric substrates in recent years has been area of interest for diverse applications such as electronic textiles and electromagnetic interference (EMI) shielding [1,2]. The metalized textiles also are a preferred choice for light and radiant heat protection according to high surface reflection [3,4].…”

“…It should be mentioned that silica nanoparticles were used in this work, due to the fact that their smaller particle sizes tend to further improve the corrosion and mechanical resistance of the composite layers, while increasing the hardness and the lifetime of the coatings, as compared to the larger particles [14,27]. However, silica nanoparticles significantly tend to be agglomerated in the plating bath due to the high surface free energy, van der Waals forces, and effective compression of the diffused double layer surrounding the particles by the high ionic strength, reducing particle suspension in the bath [31][32][33]. Therefore, SiO 2 content in the composite is low.…”

This article presents a method for the electrochemical preparation of a coating of nickel-silica nanocomposites on a carbon steel substrate. The incorporation of hydrophilic silica particles into the Ni composite coating during co-electrodeposition is so difficult due to the small size and the hydrophilicity of SiO 2 particle, generally less than 2 v% of silica is incorporated into the composite at different current densities, agitation speeds and silica concentrations. The effect of the presence of four surfactants, namely cocamidopropyl betaine (CAPB), decylglycoside (DG), cetyltrimethyl ammonium chloride (CTAC) and ammonium lauryl ether sulfate (ALES), on overcoming this problem was investigated in this research, and the surfactants were found to greatly influence the surface charge of silica, silica incorporation percentage and the microstructure of the composite. In fact, upon increasing the internal stresses, the products prepared in the presence of CAPB and DG were found to crack to some degree. CTAC was found to lead to entrapment mode silica co-deposition in the Ni coating. Furthermore, the addition of ALES into an electrolyte bath negatively supercharged silica surfaces and increased silica dispersion, which led to a dramatic increase in the silica incorporation percentages to around 14 v%. The results showed that Ni-SiO 2 composites prepared in the presence of ALES had better corrosion resistance, hardness and wear properties.

“…There are many reports which show that the amount of particles in a deposit reaches a maximum at a certain temperature; at a higher temperature, the amount decreases [5][6][7][8][9][10]. Shi et al [6] demonstrated that the amount of deposited particles increases by increasing the temperature up to 40 • C, and then decreases by further increasing temperature.…”

Morphology, Hardness, and Wear Properties of Ni-Base Composite Coating Containing Al Particle

Ni–Mo/Al composite coatings were obtained by electrodeposition from a Ni–Mo plating bath containing suspended Al particles. The factors including temperature, current density, and stirring rate affecting coating composition, wear, roughness, and morphology have been studied. It was found that properties such as hardness, roughness, wear, and the Al particle content showed parabolic behavior when changing each parameter. That means that there is a critical value for the mentioned parameters at which the properties of coatings become maximal.
