Electrospinning is a technique used to create very fine fibers from a liquid solution. In this process, an electric field is applied to a droplet of polymer solution, causing it to stretch and form a thin jet. As the jet travels through the air, it dries and solidifies into ultra-thin fibers, which can be collected on a surface. These fibers can be as small as a few nanometers in diameter, making them useful for various applications. The resulting electrospun fibers have unique properties, such as high surface area and porosity, which make them ideal for use in fields like biomedical engineering, filtration, and textiles. Researchers are exploring their potential in creating materials for drug delivery, wound healing, and even protective clothing.
