(A) Photograph showing the conical drops of a polymer solution hanging from the bottom of a PTFE tube from the drilled holes, and (B) photograph of the multiple jets ejected from the holes. (C) Photograph of an electrospinning process that uses a metallic substrate containing seven holes as the spinneret, from which seven jets were simultaneously ejected. (D and E) Photographs of electrospinning processes that use (D) a jagged metallic plate and (E) a stepped pyramid as the solid spinnerets, respectively. (F) Photographs of electrospinning processes involving various rotatory solid spinnerets to eject multiple jets simultaneously. (A and B) Reprinted with permission from ref 175.
