The invention discloses a method for making a carbon nano tube/polystyrene composite conductive material, which comprises the following steps of: firstly, preparing low-concentration solution of polystyrene by using a specific solvent and dispersing carbon nanotubes by using the solution of polystyrene; secondly, preparing another solution of polystyrene by using the same solvent according to the formula of the composite material, and uniformly mixing the two parts of solution; thirdly, adding a solvent, which is soluble with the solvent of the solution of polystyrene and not soluble with the polystyrene, into the mixed solution; and finally, obtaining the solid electro-conductive composite by filtering, collecting or drying. In the invention, the carbon nanotubes can be uniformly and stably dispersed by the chain winding of a polystyrene matrix material, the pi-pi interaction and the like, no auxiliary dispersing agents are added, and the post-chemical decoration dispersion is not used ...
