Note: Different solutions and suspensions of polymers are placed or glued on a substrate to create nanoparticle-sized particles and fibers (nanofibers) and place them using electrostatic force. .
While electric spraying is a very complex physical process that is not fully understood, when a sample of liquid stored in a thin capillary is supplied from a voltage of one thousand to ten thousand volts, due to the effect of the electric field concentration, a field A strong electric current is generated at the tip of the capillary. As the fluid begins to leave the capillary, it forms a cone with charged electric ions that have accumulated on its surface. Consequently, when the electrostatic force becomes stronger than the surface tension, the liquid sprays from the tip of the capillary and forms a fine jet. Because the jet is highly charged, the liquid immediately turns into tiny droplets, which are sprayed by the electrostatic force of each drop.
The droplets formed by the electric spray are fine. Therefore, the solvent evaporates and dries in a very short time, resulting in very fine nanofibers or nanoparticles. These nanofibers or fine particles charged by electrostatic force are absorbed by the electrode and deposited in various patterns, which can be controlled by a mask made of insulating material or an additional electrode. Nanofibers made using VGCF have already been developed as a high-performance filter. Can be used as catalytic carriers as well as high performance membranes. They are not limited to high performance filters and non-woven fabrics. Not only for textile fabrics but also for electronic components and high performance batteries as well as materials used for biological research and medical treatments, a wide variety of products are being produced.
Conclusion :
Different types of solutions and suspensions of polymers are placed or adhered to a substrate to create nanoparticle-sized particles and fibers (nanofibers) and to place them using electrostatic force.
