Abstract: PURPOSE: A method for preparing polymeric core-sheath nanofibers is provided to manufacture the polymeric core-sheath nanofibers in which a polymer grain cores are linearly arranged using a single nozzle electrospinning method. CONSTITUTION: A method for preparing polymeric core-sheath nanofibers comprises the following steps: manufacturing a polymer solution in which sheath polymer particles are dissolved; manufacturing a dispersion solution in which core polymer particles are swollen by adding the core polymer particles to the polymer solution; and manufacturing the core-sheath fibers by electrically spinning the dispersion solution using a single nozzle electrospinning method.
