|Appareils à ultrasons aux nanomatériaux Disperse|
Nanomaterials have become an integral component of products as diverse as sunscreens, performance coatings, or plastic composites. Ultrasonic cavitation is used to disperse nano-size particles into liquids, such as water, oil, solvents or resins.
The application of ultrasonics to nanomaterials has manifold effects. The most obvious is the dispersing of materials in liquids in order to break particle agglomerates. Another process is the application of ultrasound during particle synthesis or precipitation. Generally, this leads to smaller particles and increased size uniformity. Ultrasonic cavitation improves the material transfer at particle surfaces, too. This effect can be used to improve surface functionalization of materials having a high specific surface area.
