Structure and optical properties of complexes based on doped polyaniline films

摘要: Conducting polymer films are promising candidates for many molecular electronics applications: in the past years the possibility was shown to build a memory device combining polyaniline (PANI) with gold nanoparticles (GNP): conductivity varies of 3-orders-of-magnitude, with fast switching times of about 25ns [1]. If properly prepared, PANI films show metallic behaviour [2] eg in the temperature dependence of the resistivity. More recently, efforts have been directed towards the construction of a neuromorphic material system employing a combination of PANI, GNP and other polymers [3]. However the complexity of the film morphologies and electronic properties has up to now limited the application of PANI in real devices, indicating the need for more basic characterization. In this work we present investigations, by synchrotron X-ray reflectivity (XRR), grazing incidence diffraction (GID), space-resolved grazing …
