Method of making heat-shrinkable EMI/RFI shielding material

Abstract

A method of making an EMI/RFI shielding jacket comprising the steps of providing a heat-shrinkable woven fabric, coating the heat-shrinkable fabric with a conductive slurry, and drying the conductive slurry.

1 . A method of making an EMI/RFI shielding jacket comprising the steps of 
 a) providing a heat-shrinkable woven fabric;    b) coating said heat-shrinkable fabric with a conductive slurry; and    c) drying the conductive slurry.    
     
     
         2 . The method of  claim 1 , wherein the conductive slurry comprising a conductive metal, a conductive non-metal, or mixtures thereof.  
     
     
         3 . The method of  claim 2 , wherein the conductive metal is selected from the group consisting of silver, nickel, zinc, cobalt, tin, lead, platinum, gold, and alloys and mixtures thereof.  
     
     
         4 . The method of  claim 2 , wherein the conductive non-metal is graphite.  
     
     
         5 . The method of  claim 2 , wherein the conductive slurry further comprising a resin.  
     
     
         6 . The method of  claim 5 , wherein the resin is selected from the group consisting of an acrylic resin, a vinyl resin, and a polyester resin.  
     
     
         7 . The method of  claim 2 , wherein the conductive slurry further comprising a solvent.  
     
     
         8 . The method of  claim 7 , wherein the solvent is selected from the group consisting of toluene, alcohol, acetone, and stoddard solvent.  
     
     
         9 . The method of  claim 2 , wherein the conductive slurry further comprising an additive.  
     
     
         10 . The method of  claim 9 , wherein the additive is selected from the group consisting of plasticizers, flexibilizer, and antioxidants.  
     
     
         11 . The method of  claim 1 , wherein said coating step is selected from the group consisting of dipping, brushing, printing, spraying, and roller coating.  
     
     
         12 . The method of  claim 1 , wherein the heat-shrinkable woven fabric is constructed of polyolefin, polyester, or mixture thereof.  
     
     
         13 . The method of claim I, wherein the conductive slurry is absorbed into the heat-shrinkable woven fabric.
