How Does Ultrasonication Facilitate Mechanical Dispersion?
Ultrasonication utilizes high-frequency sound waves to generate cavitation bubbles within a liquid medium. These bubbles collapse violently, producing intense localized pressure and temperature fluctuations. This energy disrupts the forces holding nanoparticle agglomerates together, resulting in their dispersion into individual particles. Ultrasonication is particularly effective for aqueous suspensions and can be fine-tuned by adjusting parameters such as frequency, power, and duration.
