Core/Double-Sheath Composite Fibers from Poly(ethylene oxide), Poly(L-lactide) and Beeswax

Summary

Core-sheath fibres are normally made by coaxial electrospinning, with two solutions fed through concentric needles. This study takes a less common route: spinning a homogeneous blend of poly(ethylene oxide), poly(L-lactide) and beeswax from a single spinneret, and letting the components separate during spinning to form a core with a double sheath. The result is a layered architecture obtained without coaxial hardware, driven by the physical incompatibility of the three constituents rather than by the geometry of the needle.
