Electrospinning is a technique used to produce nanofibers with diameters ranging from submicron to nanoscale. This process involves applying a high voltage electric field to a polymer solution or melt, which creates charged jets that are collected on a substrate to form nanofibers. The process is versatile and can be used to spin a wide variety of polymeric fibers, and it has gained significant attention in recent years due to its potential applications in various fields such as electronics, materials science, and polymer engineering. Nanofibers have high surface area and porosity, making them suitable for applications such as filter media, adsorption layers in protective clothing, and optical electronics.
The electrospinning process uses a high voltage electric field to produce electrically charged jets from polymer solutions or melts, which on drying produce nanofibers. The highly charged fibers are directed towards the oppositely charged collector, which can be a flat surface or a rotating drum. In normal conventional spinning techniques, the fiber is subjected to various forces such as tensile, gravitational, aerodynamic, rheological, and inertial forces. In electrospinning, the spinning of fibers is primarily achieved by the tensile forces created in the axial direction of the flow of the polymer by the induced charges in the presence of an electric field.
The electrospinning process has been studied extensively, and research has focused on understanding the fundamental aspects of the process, the structural morphology of nanofibers, and their characteristics. The process has been shown to produce fibers with diameters ranging from 100 nm to 500 nm, which are generally referred to as nanofibers in fiber science literature. The process is simple in construction and consists of a high voltage electric source, a syringe pump, and a conducting collector. The process has been used to spin a wide variety of fine fibers, and research has focused on understanding the factors that influence the structural morphology and properties of electrospun fibers.
The electrospinning process has been shown to produce fibers with high surface area and porosity, making them suitable for applications such as filtration, catalysis, tissue scaffolds, and drug delivery systems. The process has also been used to produce nanofibers with controlled diameters and morphologies, which are important for various applications.
