    Abstract: A method and an apparatus for manufacturing core-shell capsules using electrospinning are provided to manufacture the core-shell capsules to large quantities and uniform sizes by forming cores from one polymer and forming shells from the other polymer using electrospinning techniques. An apparatus for manufacturing core-shell capsules using electrospinning comprises a double nozzle(100), an anode, a cathode, and a power supply unit for forming an electric field between the anode and cathode. The double nozzle includes an inner nozzle(110) and an outer nozzle(120). The inner and outer nozzles comprise main bodies(112,122) and spray parts(114,124) respectively. The spray part of the outer nozzle surrounds a lower part of the spray part of the inner nozzle. Solution feed lines are connected to polymer solution feed pumps for core and shell. The solution feed lines have solution branch lines(412,512) formed on predetermined portions thereof and connected to the inner and outer nozzles.
