Provided are a method for reinforcing a polyurethane nanomembrane with a carbon nanotube and a carbon nanotube reinforced polyurethane nanomembrane having high strength and high functionality, manufactured thereby, wherein the method comprises the steps of: dispersing a polyurethane and carbon nanotube into an organic solvent and manufacturing a polyurethane solution for electrospinning having 750-2500 cP of a viscosity; and electrospinning the polyurethane solution for electrospinning under the condition of 10-18 kV of applied voltage, 10-15cm of spinning distance, and 0.5-30ml/hour of discharge velocity. The carbon nanotube reinforced polyurethane nanomembrane can be widely applied to various areas, such as a waterproof material for an IT device, such as a cell phone, a high efficiency filter material, an electrode and a separation material for a secondary battery, high functional outdoor fabric, a nanofiber reinforcing composite material, and nanofiber for a sensor. |
