Dry adhesive fastener system and method of using the same

Abstract

Provided are a dry adhesive fastening system which has a relatively superior adhesion, does not almost generate noises during the attaching or detaching operation, has a simplified structure adapted to mass production requirements, and a method of using the same. For this, the dry adhesive fastening system includes a first adhesion member having a first microvillus disposed on a first board and a second adhesion member having a second microvillus disposed on a second board to contact the first adhesion, thereby providing adhesion. Also, unlike the existing velcro fastening system, the hook and loop may not be classified to improve production yield and effectiveness. Also, during the attachment/detachment, the noises may do not occur. In addition, since the microvillus having the micro or nano size is used, the adhesion may be realized even though a very small area is provided. Therefore, the dry adhesive fastening system according to the embodiment of the present invention may be applied in fields greater than those of the existing velcro fastening system.

1 . A dry adhesive fastening system comprising:
 a first adhesion member having a first microvillus disposed on a first board; and   a second adhesion member having a second microvillus disposed on a second board to contact the first adhesion, thereby providing adhesion.   
     
     
         2 . The dry adhesive fastening system of  claim 1 , wherein each of the first and second microvilli has a micro or nano size. 
     
     
         3 . The dry adhesive fastening system of  claim 1 , wherein each of the first and second boards comprises a poly ethylene terephthalate (PET) board. 
     
     
         4 . The dry adhesive fastening system of  claim 1 , wherein the adhesion between the first and second microvilli is an attraction force due to a van der waals force. 
     
     
         5 . The dry adhesive fastening system of  claim 1 , wherein each of the first and second microvilli is formed of a UV curable resin. 
     
     
         6 . The dry adhesive fastening system of  claim 1 , wherein the first and second microvilli are disposed perpendicular to the first and second boards, respectively. 
     
     
         7 . The dry adhesive fastening system of  claim 1 , wherein the first and second microvilli are surface-treated to adjust the adhesion therebetween. 
     
     
         8 . A method of using a dry adhesive fastening system, the method comprising:
 preparing a first adhesion member having a first microvillus disposed on a first board; and   preparing a second adhesion member having a second microvillus disposed on a second board to contact the first adhesion, thereby providing adhesion.   
     
     
         9 . The method of  claim 8 , wherein a force applied when the first and second microvilli contact each other is adjusted to adjust the adhesion. 
     
     
         10 . The method of  claim 8 , wherein each of the first and second microvilli is varied in diameter to adjust the adhesion. 
     
     
         11 . The method of  claim 8 , wherein each of the first and second microvilli respectively formed on the first and second boards is varied in density to adjust the adhesion. 
     
     
         12 . The method of  claim 8 , wherein each of the first and second microvilli is varied in aspect ratio to adjust the adhesion. 
     
     
         13 . The method of  claim 8 , further comprising, after the contacting of the first and second microvilli, spacing portions of the first and second boards from each other to separate the first adhesion member from the second adhesion member.
