Organic materials have enough potential to replace the role of conventional semiconductors due to their superior relative properties like light weight, flexibility, corrosion resistance, inexpensive production and ease of processing. Among the conducting organic polymers, polypyrrole (PPy) is of particular interest because of its high electrical conductivity (~ 1S/cm) and environmental stability in the doped state. In this study, we have synthesized free standing PPy composite films. These samples were then characterized by scanning electron microscopy and their charge transport study was carried out in the temperature range of 10-300 K.
