Abstract

A separation system comprising a stationary phase, a double stranded conductive polymer system contacting the stationary phase and means to place a mobile phase carrying a component to be separated from the mobile into contacting relationship with the polymer system whereby the component is captured by the polymer. The double stranded polymer is comprised of a conjugated polymer and a polyelectrolyte.

         8 . (Cancelled)  
     
     
         9 . (Original) A method for separating components in a medium comprising: 
 contacting a double stranded conductive polymer system to a stationary phase; and    flowing the medium into a contacting relationship with the stationary phase to capture and separate the components.    
     
     
         10 . The method according to  claim 9  wherein the double stranded conductive polymer system is comprised of a π-conjugated polymer and a polyelectrolyte.  
     
     
         11 . The method according to  claim 10  wherein the π-conjugated polymer is selected from the group consisting of polyaniline, plypyrrole, polythiophene, and poly(phenylene vinylene).  
     
     
         12 . The method according to  claim 10  wherein the polyelectrolyte is selected from the group consisting of poly(acrylic acid), poly(methylvinylether-co-maleic acid), poly(butadiene-co-maleic acid), poly(vinylsulfonic acid), poly(styrenesulfonic acid), poly(methacrylic acid), poly(L-glutamic acid), poly(L-Asparic acid), and poly (methylacrylate-co-acrylic acid).
