Transparent conductive nano-composites

Abstract

The present invention, in one embodiment, provides a method of forming an organic electric device that includes providing a plurality of carbon nanostructures; and dispersing the plurality of carbon nanostructures in a polymeric matrix to provide a polymeric composite, wherein when the plurality of carbon nanostructures are present at a first concentration an interface of the plurality of carbon nanostructures and the polymeric matrix is characterized by charge transport when an external energy is applied, and when the plurality of carbon nanostructures are present at a second concentration the interface of the plurality of carbon nanostructures and the polymeric matrix are characterized by exciton dissociation when an external energy is applied, wherein the first concentration is less than the second concentration.

What is claimed: 
     
         1 . A method of providing a composite comprising:
 providing a polymer matrix;   providing a bundle of carbon nanotubes within the polymer matrix; and   dispersing the bundle of carbon nanotubes into a network of carbon nanotubes, wherein the work function of the network of carbon nanotubes substantially matches the work function of the polymer matrix.   
     
     
         2 . The method of  claim 1 , wherein the step of providing the bundle of carbon nanotubes includes laser vaporization. 
     
     
         3 . The method of  claim 1 , wherein the step of dispersing the bundle of carbon nanotubes includes a solvents comprising sodium dodecyl sulfate (SDS), sodium cholate (SC), sodium dodecyl benzene sulphonate (SDBS), t-octyl phenoxy polyethoxyethanol, or a combination thereof.
