Thumbnail image of graphical abstract

Porous, fibrous carbon nanofibers containing hollow cores (see image) are fabricated by electrospinning two immiscible polymer solutions followed by thermal treatment at 1000 °C in an inert atmosphere. This new type of carbon nanofibers has controlled porosity combined with a low density and expected high electrical and mechanical properties due to an interlinked fiber morphology, and may be utilized as an efficient electromagnetic shielding material.
