Seminar On Conducting Polymers And Applications

CONDUCTING POLYMERS SEMINAR REPORT AND PPT

Polymers (plastics) are known to have good insulating properties and are among the most used materials in the modern world. However, it has been discovered that there are some polymers which have conducting properties. Conducting polymers are polymer materials with metallic and semiconductor characteristics,a combination of properties not exhibited by any other known material. A key property of a conductive polymer is the presence of conjugated double bonds along the backbone of the polymer. In conjugation, the bonds between the carbon atoms are alternately single and double.

Since the electrons in a conjugated system are only loosely bound, electron flow may be possible. Every bond contains a localized “sigma” bond which forms a strong chemical bond.In addition, every double bond also contains a less strongly localized “pi” bond which is weaker. These enable the electrons to be delocalized over the whole system and so be shared by many atoms. This means that the delocalized electrons may move around the whole system. However, conjugation is not enough to make the polymer material conductive. In addition,the polymer material needs to be doped for electron flow to occur. Doping is either the addition of electrons (reduction reaction) or the removal of electrons (oxidation reaction) from the polymer.
