Electronically conducting polymers (ECPs) such as polyaniline (PANI), polypyrrole (PPy) and po 1 y(3.4-cthy 1 cncdi oxyth iophcnc) (PEDOT) have been applied in supercapacitors, due to their excellent electrochemical properties and lower cost than other ECPs. We demonstrated that multi-walled carbon nanotubes (CNTs) prepared by catalytic decomposition of acetylene in a solid solution are very effective conductivity additives in composite materials based on ECPs. In this paper, we show that a successful application of ECPs in supercapacitor technologies could be possible only in an asymmetric configuration, i.e. with electrodes of different nature. 

The future remains bright for the use of carbon materials in batteries. In the past several years, several new carbon materials have appeared mesophase pitch fibers, expanded graphite and carbon nanotubes. New electrolyte additives for Li-Ion permit the use of low cost PC based electrolytes with natural graphite anodes. Carbon nanotubes are attractive new materials and it appears that they will be available in quantity in the near future. They have a high ratio of the base plane to edge plain found in HOPG. The ultracapacitor application to deposit an electronically conductive polymer on the surface of a carbon nanotube may be the wave of the future. 

CNT-doped conducting polymers possess improved mechanical, chemical, and optical properties. They also provide a simple strategy for making aligned CNTs. The disappearance of the characteristic peaks of carbon nanotubes in the FTIR spectrum of polymer/CNT composite films is normally an indication of perfect enwrapping of CNTs with the deposited conducting polymer [162, 163], Zhang et al. [40] have studied the...

The differently produced conductive polymer structures described above all have enhanced conductivity, which can be employed in microelectronics [44] and as sensors using immobilized enzymes [46, 47[. Martin and coworkers used polarized infrared absorption spectroscopy to access the alignment of the polymer fibers on the outer surface of the nanotubes [48[. The study showed that the enhancement of the conductivity is due to the alignment of the polymer fibers on the outer surface of the tubes.

Saratz (et al., 2005) reviewed carbon nanotubes (CNTs) and described potential applications in fields such as molecular electronics (Saratz et al 2005), conductive polymers (Saratz et al. 2005 Soussi et al., 2001 Daloglu, Yilmaz, and Alptikin 2004), and energy storage (Soussi et al. 2001 Daloglu et al., 2004, Mach and Tardy, 2001 Mach and Tardy, 2001).

Finally, the study of different types of composites has been briefly discussed, as an example to exploit the properties of the carbon nanotubes to modify those of conducting polymers, and monitor their emission features as needed in devices like light emitting diodes. 

Clear quantitative descriptions of the transport in poorly defined material systems such as acid-doped PANI or mats and ropes of nanotubes are difficult to develop. Even more problematic is the description of a composite of the two. Nevertheless we do believe that there are some conclusions that can be drawn from consideration of the data. A large amount of work has gone into understanding the transport in heterogeneous systems such as conducting polymers and nanotube mats [25, 27-31]. However, that work has focused on understanding each separately rather than as a combined composite material. Interestingly, when com-...
