Electrospinner: How to select the type of electrostatic spraying combined with ultrasonic spraying to achieve micro/nano particle composite?

Background

The development of electrospinning technology can be traced back to the 1930s to the 1980s, but the development was relatively slow at that time, mainly focusing on the research of electrospinning devices.

In the 1990s, the Reneker research group of the University of Akron in the United States conducted in-depth research on the electrospinning process and application, which promoted the development of technology.

In recent years, with the development of nanotechnology, electrospinning technology has achieved rapid development, which has aroused great interest in the scientific research and industrial circles.

The development of electrospinning technology has gone through four stages: research on the spinnability of polymers, diversification of electrospinning nanofiber components and fine control of structure, application of electrospinning fibers in various fields, and batch manufacturing of electrospinning fibers.

Advantages of electrostatic spraying and ultrasonic spraying

Excellent nanoparticle preparation effect: Ultrasonic spraying can produce very fine droplets, combined with electrostatic spraying, it can achieve precise control and uniform dispersion of nanoparticles.

Efficient use of raw materials: Combining ultrasonic spraying and electrostatic spraying technology can more effectively use raw materials and reduce waste generation. Due to the controllability of particle size, the utilization efficiency of raw materials can be better controlled

Enhanced surface uniformity: Electrostatic spraying forms a uniform thin layer on the surface of nanoparticle composite materials, which helps to improve the surface uniformity of composite materials and is of great significance for coating materials or drug-loaded materials

Controllable process conditions: The combination of the two technologies can flexibly adjust the process conditions as needed, including ultrasonic amplitude, electrostatic field strength, etc., to meet the requirements of different applications for nanoparticle composite materials

Improved production efficiency: Ultrasonic spraying and electrostatic spraying are both relatively efficient preparation technologies, and combined use can improve production efficiency

Hardware required to achieve electrostatic spraying and ultrasonic spraying composite

Ultrasonic atomization component: An ultrasonic atomization nozzle is standardly equipped. The generator is located inside the electrical box and is controlled by the panel to achieve high-throughput atomization capability for low-viscosity liquids. When used independently, a nanoparticle deposition layer can be prepared

Yongkang Leye All-Round SS-X3 Electrospinning Equipment: It integrates two different nanoparticle generation methods, electrostatic atomization and ultrasonic atomization. It can not only form nanoparticle deposition in situ on the primary surface of nanofibers to modify nanofibers, but also form hybrid structures between nanoparticles of different components
