摘要: The specific aspects of phase formation phenomena involved in electrodeposition conducting polymer layers are critically discussed. mechanism and the properties electrodeposited thin polyaniline (PANI) films on Au(111) p-Si(111) investigated by means transient measurements, cyclic voltammetry, electrochemical impedance spectroscopy atomic force microscopy (AFM). Experimental results show that initial stages PANI can be described a model including progressive appearance preferential 2D growth islands. electropolymerization process substrates is preceded anodic an inhomogeneous SiO2 layer giving rise to 3D redox influenced strongly electronic band structure silicon.
