What Are The Applications of Ultrasonic Nanodispersion Equipment?

Ultrasonic nanodispersors are key devices that utilize the cavitation effect, mechanical vibration, and shear force of ultrasound to achieve uniform dispersion of nanomaterials in liquid media. Their core advantage lies in their ability to effectively break up nanoparticle agglomerations and improve the stability and uniformity of the dispersion system. Consequently, they have broad and important applications in multiple fields. The following is a detailed introduction to their main application areas:

I. Nanomaterial Preparation and Modification

In the production and processing of nanomaterials, ultrasonic nanodispersion equipment is a core tool, directly impacting the material's performance and application results.

Nanoparticle Dispersion

For nanomaterials prone to agglomeration, such as metal nanoparticles (such as silver, copper, and gold), metal oxide nanoparticles (such as TiO₂, ZnO, and SiO₂), and carbon nanomaterials (such as carbon nanotubes, graphene, and fullerenes), ultrasonic cavitation generates localized high temperatures and high pressures, coupled with intense liquid microfluidic shear, breaking down the van der Waals forces or hydrogen bonds between the particles, achieving monodispersity or uniform dispersion.

For example, in graphene preparation, ultrasound can exfoliate graphene sheets from graphite and disperse them in a solvent, preventing agglomeration and preserving their excellent electrical and mechanical properties.

Nanocomposite Preparation

Used to uniformly disperse nanoparticles into polymer matrices (such as resins, rubbers, and plastics) to prepare high-performance nanocomposites. For example, dispersing nano-SiO₂ particles in epoxy resin can improve the material's strength, wear resistance, and heat resistance; dispersing carbon nanotubes in rubber can enhance its conductivity and mechanical properties.

II. Biomedicine

Ultrasonic nanodispersion technology plays an important role in drug delivery and the preparation of biologics, improving drug bioavailability and safety.

1. Nanopharmaceutical Preparations

Ultrasonic dispersion is used to prepare poorly soluble drugs into nanosuspensions, nanoliposomes, nanomicelles, and other formulations, ensuring uniform particle size and stable dispersion, thereby improving drug solubility, permeability, and targeting. For example, the anti-tumor drug paclitaxel, when dispersed in nanoliposomes, can reduce toxic side effects and enhance its targeting to tumor cells.

2. Biomacromolecule Dispersion

Ultrasonic nanodispersion is used to disperse and renature biomacromolecules such as proteins and nucleic acids, preventing their aggregation and precipitation in solution and preserving their biological activity. For example, in vaccine preparation, ultrasound can evenly disperse viral particles or antigenic proteins, ensuring vaccine efficacy and stability.

3. Nanobiological Probes

When preparing nanoprobes for medical imaging (such as quantum dots and magnetic nanoparticles), ultrasonic dispersion is used to ensure uniform distribution in biological media, improving imaging accuracy and sensitivity.

III. Energy and Environment

In the preparation of energy materials and environmental pollution control, ultrasonic nanodispersion technology can optimize material properties and improve reaction efficiency.

1. Energy Material Preparation

Battery Materials: In the preparation of lithium-ion battery cathode materials (such as LiFePO₄) and anode materials (such as silicon-based nanoparticles), ultrasonic dispersion can reduce particle agglomeration, increase the specific surface area and electrochemical performance of the electrode materials, and enhance the battery's capacity and cycle life.

Fuel Cells: Used to disperse fuel cell catalysts (such as platinum-based nanoparticles), ensuring uniform distribution of the catalyst on the electrode surface, improving catalytic activity and fuel utilization.

Solar Cells: In the preparation of perovskite solar cells and quantum dot solar cells, ultrasonic dispersion can optimize the uniformity of the light absorption layer material and enhance photoelectric conversion efficiency.

2. Environmental Governance

Wastewater Treatment: Ultrasonic dispersion of nanophotocatalysts (such as TiO₂ and ZnO) into wastewater increases their contact area with pollutants, enhancing photocatalytic degradation efficiency, and is used to treat pollutants such as organic dyes and pesticides. Air purification: Prepare nano-scale adsorption materials (such as activated carbon nanoparticles and molecular sieves) and improve their adsorption capacity for harmful gases such as formaldehyde and VOCs through ultrasonic dispersion.

IV. Coatings and Ink Industry

In fine chemical industries such as coatings and inks, ultrasonic nanodispersion technology can improve product performance and appearance, enhancing application effectiveness.

1. High-Performance Coatings

Used in the preparation of nanocoatings (such as antimicrobial coatings, anticorrosive coatings, and self-cleaning coatings), it evenly disperses functional nanoparticles (such as silver nanoparticles and SiO₂ nanoparticles) into the coating matrix, ensuring uniform and stable coating performance. For example, uniform dispersion of silver nanoparticles in antimicrobial coatings enhances the antibacterial effect; dispersion of nano-ZnO in anticorrosive coatings improves the coating's corrosion resistance.

2. High-End Inks

In nanoinks (such as conductive inks and anti-counterfeiting inks), ultrasonic dispersion ensures uniform distribution of conductive nanoparticles (such as silver nanowires and carbon nanotubes) or functional pigments, improving the ink's conductivity, printing accuracy, and stability. These technologies are suitable for applications such as flexible electronics and printed circuits.
