1. Understanding Electrospinning
Electrospinning is a versatile and precise technique that involves using an electric field to create nanofibers from a polymer solution or melt. The process begins by feeding the polymer solution through a syringe connected to a high-voltage power supply. The electrical charge causes the solution to form a jet that stretches and elongates into ultra-fine fibers as it moves towards a collector. The resulting electrospun nanofibers possess unique properties such as high surface area, porosity, and tunable morphology, making them highly desirable for numerous applications.
