• Sommario/riassunto: Electrospinning is from the academic as well as technical perspective presently the most versatile technique for the preparation of continuousnanofi bers obtained from numerous materials including polymers, metals, and ceramics. Shapes and properties of fi bers can be tailoredaccording to the demand of numerous applications including filtration, membranes, textiles, catalysis, reinforcement, or biomedicals.This book summarizes the state-of-the art in electrospinning with detailed coverage of the various techniques, material systems and theirresulting fi ber structures and prope
