Figure 6.

(A) Schematic illustration of a setup for electrospinning a polymer melt onto a static collector. (B) Illustration of electrohydrodynamically driven air flow for melt electrospinning, which is capable of enhancing the heat transfer between the jet and the surrounding medium (typically, air) by 1 order of magnitude. (C) Temperature profiles showing rapid cooling of electrospun nylon-6 (N6), PP, and PLA molten jets, as well as a photograph of the PLA molten jet. (D) Photograph of a molten jet during melt electrospinning. The molten pendant droplet has one single Taylor cone that is elongated while the jet is particularly long and is visible over almost the entire distance to the collector. (E and F) SEM images showing typical examples of coiled fibers commonly observed during melt electrospinning. The coiled fibers were formed from molten jets of (E) PP and (F) a blend of poly(ethylene glycol) (PEG)-b-PCL and PCL, respectively. (A) Reprinted with permission from ref 99.
