Nov 17, 2022Most nanoparticles such as nanoclay, graphene, as well as CNTs with high surface energy tend to aggregate together so that difficult to disperse in liquid media. Stir mixer, as a common tool, supplies high shear energy to break the aggregate into smaller particles and achieve their dispersion in water, organic solvents, or polymer matrix.

Abstract: Magnetically hard PrCo 5 nanoparticles have been produced by using surfactant-assisted high-energy ball milling techniques. The use of surfactant leads to the dispersion of the crashed particles and prevents them from rewelding during the milling process. Heptane was used as the milling medium, and oleic acid as the surfactant.
