Conductive polymers take much interest because of their electroactive definition as new generation smart biomaterials beside of their potential usage in proton exchange membrane fuel cells. Partially sulfonated styrene(ethylene-butylene)-styrene (sSEBS) triblock copolymer based films (coded SEBS68 with the content of 68% SEBS, 5% PP, 26,5% Wax and 0,5% stabilizer) have been focused in the present study. Chemical manipulations have been done during the synthesis of the films for formation of nano-scale cylindrical like globular and lamellar like nematic aggregations. Association of the nano aggregations and nano-domains in the films were investigated by using small- and wide-angle X-ray scattering methods. Microscale surface morphologies and features were also examined by a compact non-contact 3D surface profiler system. The results show that the changes in the nanostructures and the surface morphologies are dependent on sulfonation time. With sulfonation time of 4 min, the system could reach optimum physico-chemical properties, including the optimized size of phase segregation tunnels. It was also found that the modified polymer morphologies with nanostructural features are effective on antimicrobial activities against the different test microorganisms studied.
