Electroless Nanocomposite Coatings: Synthesis, Characteristics, and Applications

“…Various types of surfactants, namely, anionic, cationic, and nonionic, are used for this purpose. The most commonly used surfactants are cetyltrimethylammonium bromide (CTAB), dodecyltrimethylammonium bromide (DTAB), hexadecyltrimethylammonium bromide (HTAB), sodium dodecyl sulfate (SDS), 1,3-toloyltriethanolammonium chloride (TTAC), tetraethyleneglycol dodecyl ether (Brij 30), polyethylene glycol (PEG), and fluorosurfactants [6,11,14,16,17,[27][28][29][30]. It is important to understand the role of surfactants and its interaction with the nanoparticles so that an effective dispersion of nanoparticles could be achieved in the plating bath.…”

“…However, at higher concentrations (1 mg/g for cationic and anionic, 2 mg/g for nonionic), the level of incorporation is drastically decreased (3.0, 1.0, and 1.5 wt% for nonionic, cationic, and anionic, respectively). According to Zielinska et al [28], a higher level of incorporation of ZrO 2 nanoparticles in the EL Ni-P matrix is achieved with the addition of DTAB (cationic surfactant), whereas addition of SDS (anionic surfactant) and Brij 30 (nonionic surfactant) tends to destabilize the plating bath in about 20 min. This is mainly due to the change in surface charge on the ZrO 2 nanoparticles following the adsorption of these surfactants ( Table 1).…”

Effect of surfactants on the coating properties and corrosion behaviour of Ni–P–nano-TiO2 coatings

“…The essential outcomes of such particle reinforcement can only be achieved if the solid phase is well dispersed in the metal coating [16]. Undoubtedly, the properties of Ni-P composite coatings is highly dependent on the stable dispersion of the nano particles in the plating bath, otherwise uniform distribution of particles will get affected, owing to segregation and agglomeration of nano particles with high surface energy and activity in the plating bath [17].…”
