“…By increasing the concentration of the surfactant the particles become hydrophilic again, once a bilayered surfactant coating forms. With the formation of a bilayer the zeta-potential is increased and the stability of the suspension is improved, because of the electrostatic and steric repulsions [24].…”

“…Aggregation experiments were carried out with sodium dodecyl benzene sulfonate (SDBS, Sinopharm Chemical Reagent Co., Ltd., China, m = 272.38 g/mol, AR) and potassium chloride (KCl, Tianjin Qilun Chemical Technology Co., Ltd., China, m = 74.45 g/mol, AR). SDBS is a common polymer surfactant for ceramic materials (Chai, Cheng, Peng, Huang, & Zhang, 2006;Ge & Liang, 2010;Panya, Arquero, Franks, & Wanless, 2004;Panya, Wanless, Arquero, & Franks, 2005;Satchawan et al, 2014) and was used at dosages of 0.5, 1.0, and 3.0 wt% (based on the weight of the solid in suspension). In the case of KCl, the suspensions were firstly diluted with distilled water (conductivity: 0.001 S/m at 25 • C) from the ground suspension of 30 wt% to dilute suspensions of 5, 10, and 20 wt%, and then KCl was added into each suspension at 5, 10, 20, and 30 wt% to accelerate the aggregation process at the concentrations of 0.1, 0.3, and 0.5 M, respectively.…”

“…If, however, there is enough incentive for a few surfactant ions to adsorb onto the surface of the particles, then further adsorption can subsequently be driven through hydrophobic interactions (Panya et al, 2004). An increase of the particles' zeta potential with the addition of SDS to the solution ( Figure 8) provides evidence of surfactant adsorption.…”

Optimum particle dispersion is an essential feature for composite coatings carried out on the autocatalytic electroless nickel plating platform. In this regard, the potential influence of an anionic surfactant, sodium dodecyl sulphate (SDS), on the dispersion stability of a ceramic, yttria stabilized zirconia (YSZ), in an acidic electroless nickel solution of pH 4.9 has been assessed in this study. Ultra violet-visible spectrophotometry was used in accordance with the Beer-Lambert law (-log (I 1 = I 0 ) ¼ A) to evaluate the rate of YSZ particle sedimentation in electroless nickel solutions with and without surfactant. Measurement of the particles' zeta potential at each surfactant concentration was conducted in parallel with the UV-vis tests with the aim of establishing the interaction among the surfactant, YSZ particles, and electroless nickel solution. A slight increase in the negative magnitude of the particles' zeta potential indicated the adsorption of SDS onto the particles' surface and a possibility of contributing to its stability. However, the surfactant's inability to counteract an electroless nickel solution-induced particle accretion resulted in the observation of poor YSZ particle stabilities at all the investigated surfactant concentrations.Electroless co-deposition of nickel and the ceramic yttria stabilized zirconia (YSZ) recently emerged as a method of manufacturing solid oxide fuel cell (SOFC) electrodes (Davidson and Waugh, 2009). Its non-requirement of a high energy sintering stage not only significantly reduces currently high SOFC manufacturing costs, but also offers an opportunity to eliminate certain high-temperature related problems such as material warpage. While nickel provides the essential platform for electronic conductivity and fuel catalysation, YSZ, in addition to preventing the coarsening of nickel at high operating temperatures ($1000 C), relieves the thermal expansion mismatch between the anode and the electrolyte. Electroless nickel solution is the medium wherein the co-deposition process occurs. Addition of second-phase particles such as YSZ to the solution results in the manufacture of a composite coating.
