What Techniques are Used for Mechanical Dispersion?
Several techniques are employed to achieve mechanical dispersion of nanoparticles:
Ultrasonication: Uses high-frequency sound waves to create cavitation bubbles that break apart nanoparticle agglomerates. Ball Milling: Involves grinding nanoparticles with balls of various materials in a rotating cylinder, leading to particle size reduction through impact and attrition. High Shear Mixing: Utilizes high-speed rotating blades to generate shear forces that disperse nanoparticles in liquids. Microfluidization: Forces nanoparticle suspensions through narrow channels at high pressures to break apart agglomerates.
