2 Carbon Nanotubes/Conducting Polymers Composites for Capacitor 

Generally, a synergy effect is obtained between the components of composite, that is, CNTs and ECP. A nanocomposite gives better results than its components alone. The most attractive ECP as supercapacitor materials are polyaniline (PANl), polypyrrole (PPy), and 3,4-ethylene diox3d hiophene (PEDOT) because of the quick redox reactions (example of PPy)

Manganese Oxide/Carbon Nanotube Nanocomposites for Electrochemical Energy Storage Applications... 

Observed in 1991 by lijima [72] by transmission electron microscopy as a by-product of the reaction of the synthesis of fullerenes, carbon nanotubes can be described as a rolling-up of graphite planes. Because of its relation to graphite as well as its nanometer size and one dimensionality, this new material is expected to present unique properties. Several applications have been envisaged for electronics [73-75], for energy storage [76,77] or in medicine [78]. They also present unique mechanical properties [79] and many studies are presently being performed with the aim to use them as reinforcements in polymers [80-82].

Apart from the promising electrochemical properties that will be exhaustively discussed through this chapter, carbon nanotubes have become a hot research topic due to their outstanding electronic, mechanical, thermal, optical and chemical properties and their biocompatibility. Near- and long-term innovative applications can be foreseen including nanoelectronic and nanoelectromechanical devices, held emitters, probes, sensors and actuators as well as novel materials for mechanical reinforcement, fuel cells, batteries, energy storage, (bio)chemical separation, purification and catalysis [20].
