ELECTROSPINNING – ELECTROSPRAYING TECHNIQUES
The history of modern electrostatic spinning is the classic case of a scientific rediscovery. Indeed coupling electrical phenomena and fluids has been fascinating physicist for centuries, as reported in many studies and by the time started to call “electrospinning”
Electrospinning shares characteristics of both electrospraying and conventional solution dry spinning of fibers.
WHAT’S ELECTROSPINNING ?
Electrospinning is a fiber production method which uses electric force to draw charged threads of polymer solutions or polymer melts up to fiber diameters in the order of some hundred nanometers. Electrospinning shares characteristics of both electrospraying and conventional solution dry spinning of fibers.
Briefly; electrospinning uses an electrical charge to draw very fine (typically on the micro or nano scale or nanofiber) fibres from a liquid or polymer solution.
Nowadays basic Electrospinning can be described as; The electrostatic force is applied to produce electrically charged jets out of viscoelastic polymer solutions, solvent is evaporated in time and nano-micro structures are obtained at the end of the process.
