(A) Schematic illustration showing the formation of core− sheath nanofibers by emulsion electrospinning. (B) Schematic illustration showing the formation of core−sheath nanofibers that contain an array of colloids in the core by electrospinning a polymer solution containing cross-linked and swollen polymer colloids. (C) Confocal laser scanning microscopy image of a typical core−sheath fiber consisting of a PCL sheath and PNIPAAm microgel particles in the core. (A) Reprinted with permission from ref 428.
