Electrospinning is a straightforward method to produce polymer fibers from polymer solutions, with diameters in the range of 100 nm. Electrospun fibers often have beads in regular arrays. The viscoelasticity of the solution, charge density carried by the jet, and the surface tension of the solution are the key factors that influence the formation of the beaded fibers.
