Ultrasonic dispersion of nanomaterials is an advanced technology, which plays an important role in the preparation and application of nanomaterials.
Ultrasonic dispersion uses the high-frequency vibration energy of ultrasonic wave to produce strong cavitation effect and mechanical stirring effect in the liquid. When the ultrasonic wave acts on the liquid containing nanomaterials, the formation and rupture of the cavitation bubble will produce local high temperature, high pressure and strong impact force, which can effectively break the agglomeration between the nanoparticles and make them evenly dispersed in the liquid.
This decentralized approach has many advantages. First of all, it can achieve efficient dispersion effect in a short time, greatly improving the dispersion quality and stability of nanomaterials. Secondly, there is no need to add additional chemical dispersants during the ultrasonic dispersion process, which avoids the impact on the properties of nanomaterials and environmental pollution. In addition, the method is simple to operate and easy to control, and can be applied to different kinds of nanomaterials and liquid systems.
Ultrasonic dispersion of nanomaterials has been widely used in many fields. In the field of medicine, it can be used to prepare nano-drug carriers, nano-biosensors, etc., to improve the efficacy and biocompatibility of drugs. In the field of materials science, it can be used to prepare high-performance nano-composite materials, nano-coatings, etc., to improve the performance and function of materials. In the field of environmental protection, it can be used to treat nano-pollutants in wastewater and exhaust gas to achieve environmental purification and restoration.
In short, the ultrasonic dispersion technology of nanomaterials provides strong support for the development and application of nanomaterials, and has broad development prospects.
