De‐agglomeration and Dispersion of Nano‐TiO₂in an Agitator Bead Mill

Effect of sodium dodecylsulfate monomers and micelles on the stability of aqueous dispersions of titanium dioxide pigment nanoparticles against agglomeration and sedimentation

“…Most of the literature studies have focused on ways to stabilize TiO 2 particles against agglomeration [6][7][8][9][10][11][12][13][14][15][16] by using surfactants or polymers as dispersants. When a dispersant adsorbs on the particles surface, it affects the electrostatic interactions and often introduces additional long-range steric interactions.…”

Preparation of dispersed aluminum hydroxide nanoparticles via non-aqueous route and surface modification

“…A variety of methods for preparing nanoparticles have been developed. Although nanoparticle suspensions with good stability can be achieved, complete dispersions on the primary particle size level still remain a challenge [1,2]. Inorganic nanoparticles are easy to agglomerate in mediums and show poor dispersion capacity in organic solvents, which largely limits their applications in many fields.…”

De-Agglomeration and Dispersion Behavior of TiO2Nanoparticles in Organic Media Using 3-Methacryloxypropyltrimethoxysilane as a Surface Modifier

“…These results are similar to the de-agglomeration of TiO 2 nanoparticles in BAc in the presence of polymer dispersant. [4,7] Figure 1 also shows that higher molar ratio of MPS-to-TiO 2 leads to smaller mean particle size at the same grinding time, and finally, results in smaller limited fineness. However, nearly the same limited finenesses ($163 nm) are achieved at MPS-toTiO 2 molar ratio of 0.2:1 and 0.3:1.…”

“…De-agglomeration and attaching of organic species onto the surfaces of inorganic nanoparticles are usually necessary to improve their dispersion and compatibility with organic media. In organic coatings field, inorganic nanoparticles are generally de-agglomerated in organic solvents via a bead milling process [4][5][6][7] in the presence of organic dispersants (or ligands) and then used as the additives of coatings. With this process, a contradiction between the compatibility of nanoparticles with organic solvents and the compatibility of nanoparticles with the organic binders (i.e., polymer, oligomer, and monomer) of coatings may come forth.…”
