Thin polymer blend films of conducting homopolymers — •M. Ruderer, J.-F. Moulin, and P. Müller-Buschbaum — TU München, Physik-Department E13, James-Franck-Str. 1, D-85747 Garching, Germany

Two conduction homopolymers, MEH-PPV Poly(1-methoxy-4-(2-ethylhexyloxy)-p-phenylenevinylene)) and P3BT (poly(3-butylthiophene-2,5-diyl), are blended with different ratios. Thin films are prepared via spin-coating on glass slides. The resulting surface structures are characterized by optical microscopy and atomic force microscopy (AFM). With optical spectroscopy (UV/Vis) in reflection and transmission geometry the absorbed part of the optical spectrum is detected. The resulting parameters are correlated with the bulk phase diagram of the components.
