Nano fiber composite sheet and method of manufacturing the same

Abstract

There is provided a method of manufacturing a nanofiber composite sheet, the method including preparing a base sheet, surface-treating the base sheet, and forming a substrate layer having a nanofiber structure on the surface-treated base sheet.

What is claimed is: 
     
         1 . A method of manufacturing a nanofiber composite sheet, the method comprising:
 preparing a base sheet;   surface-treating the base sheet; and   forming a substrate layer having a nanofiber structure on the surface-treated base sheet.   
     
     
         2 . The method of  claim 1 , wherein the base sheet includes a polymer material. 
     
     
         3 . The method of  claim 2 , wherein the polymer material is at least one selected from a group consisting of polypropylene (PP), polyethylene (PE) and polyethylene terephthalate (PET). 
     
     
         4 . The method of  claim 1 , wherein the surface-treating is performed by irradiating energy onto the surface of the base sheet. 
     
     
         5 . The method of  claim 1 , wherein the surface-treating is performed by at least one method selected from a group including a corona treatment, a plasma treatment and an electromagnetic wave irradiation treatment. 
     
     
         6 . The method of  claim 1 , wherein the forming of the substrate layer is performed by an electrospinning process. 
     
     
         7 . The method of  claim 1 , further comprising, after the forming of the substrate layer, compressing the base sheet and the substrate layer. 
     
     
         8 . A nanofiber composite sheet comprising:
 a base sheet having a hydrophilic group formed on a surface thereof ; and   a substrate layer having a nanofiber structure and formed on the surface of the base sheet, the base sheet having the hydrophilic group formed on the surface thereof.   
     
     
         9 . The nanofiber composite sheet of  claim 8 , wherein the base sheet includes a polymer material. 
     
     
         10 . The nanofiber composite sheet of  claim 9 , wherein the polymer material is at least one selected from a group consisting of polypropylene (PP), polyethylene (PE) and polyethylene terephthalate (PET). 
     
     
         11 . The nanofiber composite sheet of  claim 8 , wherein the hydrophilic group is formed by irradiating energy onto the surface of the base sheet. 
     
     
         12 . The nanofiber composite sheet of  claim 8 , wherein the hydrophilic group is formed by at least one method selected from a group including a corona treatment, a plasma treatment and an electromagnetic wave irradiation treatment. 
     
     
         13 . The nanofiber composite sheet of  claim 8 , wherein the substrate layer is formed by an electrospinning process.
