Adsorption mechanism and dispersion efficiency of three anionic additives [poly(acrylic acid), poly(styrene sulfonate) and HEDP] on zinc oxide

EPD-deposited ZnO thin films: a review

“…Similarly, Dange et al measured the adsorption of three anionic additives -polyacrylic acid (PAA), polystyrene sulfonate (PSS), and hydroxyethylidene diphosphonic acid (HEDP), onto ZnO nanoparticles in order to evaluate their dispersion efficiency [52]. They observed that the adsorption process was different depending on the amount of dispersant added: at low additive concentrations, the additives formed complexes with Zn 2+ ions in solution which became totally adsorbed onto the particles, whereas A summary of the reported surface charge modifiers used for the stabilization of ZnO suspensions for EPD is shown in Table 1.…”

The rheological behavior and stability of Mg(OH)2 aqueous suspensions in the presence of sodium polyacrylate

“…It is well known that polyeletrolytes have been successfully used to reduce the viscosity and stabilize the high solid loading suspensions [14][15][16][17][18][19][20][21][22][23][24]. Sodium polyacrylate (NaPA) with low molecular weight is one of the most frequently applied polyelectrolytes as a dispersant to induce stability by electrosteric stabilization [15,25].…”

Influence of sodium dodecyl sulfate on the fabrication of zinc oxide nanoparticles

“…However, the average agglomerate size remained at 2.0 lm with a unimodal peak located at 0.35 lm when the addition of SDS is higher than 2 wt%. Figure 4 presents the influence of SDS on the XRD patterns of Zn 5 (CO 3 ) 2 (OH) 6 The solution basicities were reported to have a determinative effect on the morphology of ZnO, via changing the zinc species, the charge and surface potential of the precipitate [13][14][15]. Here, the solution pH was controlled at 7.5-8.0 to gain the maximum zinc yield.…”
