Cover Feature: Coaxial Electrospinning Formation of Complex Polymer Fibers and their Applications (ChemPlusChem 10/2019)

The cover feature shows the versatility of coaxial electrospinning in forming fibers with complex structures. Polymer solutions are fed into a nozzle with concentric openings from which a coaxial liquid jet is extracted by the application of an electric field. The resulting core–sheath fibers with nano/micrometer diameter are formed with a variety of structures and show properties that are useful in many important applications. More details are given in the Review by D. Han and A. Steckl on page 1453 in Issue 10, 2019 (DOI: 10.1002/cplu.201900281).
