ABSTRACT
Nanotechnology and application as conjugated polymeric materials in nanofibers, nanocoreshell, nanocomposite, nanolithography, and semiconductive products provides a wide range of implementation, such as sensors, fuel cell, and organic light-emitting diode. Conducting polymers (CP) behave like semiconductors in terms of conductivity but normally when they are synthesized they indicate low conductivity because of being neutral. The electronic and optical properties of p-conjugated polymers result from a number of states around the highest occupied and the lowest unoccupied levels. Conjugated polymers have a conjugated p system and p bands. For conjugated polymers the gap energy is in the range of 1.5 eV to 3 eV, that is, in the range of Vis light and the near infrared, similar to inorganic semiconductors. CPs can be defined as the cationic and anionic salts of highly conjugated polymers. CP nanocomposites exhibit multifunctional and unique properties. Electroactive polymers have a very specific chemistry, which may limit the obtention of purely conjugated polymers.
