Conjugated polymers materials

The science and technology of conducting polymers are inherently interdisciplinary they fall at the intersection of three established disciplines chemistry, physics and engineering hence the name for this volume. These macromolccular materials are synthesized by the methods of organic chemistry. Their electronic structure and electronic properties fall within the domain of condensed matter physics. Efficient processing of conjugated polymer materials into useful forms and the fabrication of electronic and opto-electronic devices require input from engineering i. e. materials science (more specifically, polymer science) and device physics. 

Similar approach has also been taken by Ferain and Legras [133,137,138] and De Pra et al. [139] to produce nanostructured materials based on the template of the membrane with etched pores. Polycarbonate film was also of use as the base membrane of the template, and micro- and nanopores were formed by precise control of the etching procedure. Their most resent report showed the successful formation of ultrasmall pores and electrodeposited materials of which sizes were as much as 20 nm [139]. Another attractive point of these studies is the deposited materials in the etched pores. Electrochemical polymerization of conjugated polymer materials was demonstrated in these studies, and the nanowires based on polypyrrole or polyaniline were formed with a fairly cylindrical shape reflecting the side wall structure of the etched pores. Figure 10 indicates the shape of the polypyrrole microwires with their dimension changes by the limitation of the thickness of the template.

We previously noted that both intrachain and interchain transport of carriers mdst be considered when examining the electronic conductivity of conjugated polymer materials. We now describe a theoretical model recently developed by Pearson and coworkers that can be used to examine the effect of polymer molar mass and polymer orientation on the conductivity behavior of conjugated polymer materials. 

Conjugated organic polymers have been studied extensively over the last twenty years, in part, because of the fundamental and technological interest in their optic and electronic properties. Applications that have been demonstrated for these materials include their use as batteries, sensors, electrochromic devices, light-emitting diodes, and field effect transistors.(i-9) A unique advantage of conjugated polymer materials for these applications is that the properties of the polymer can be...
