Precious Polymer
Polymers are usually organic substances
composed of a very large number of like
molecules.
Polymers are divided, on the basis of their
mechanical properties and strength, into three
categories: rubbers or elastomers,plastics and
fibers.

Conducting Polymer
Polymers are generally insulators because the
organic molecules of which they are composed
have no free electrons to carry current; all the
electrons are held firmly by atoms forming the
molecules.
Polymers in which the carbon atoms in the
backbone are linked by double bonds have the
potential to conduct electricity, especially when a
number of such bonds occur in the vicinity of
each other.

Why Conducting plastic ?
The electrons in one of the two bonds of the
double bond are held a little bit less strongly and
can get away from the atoms forming the bond.
The electrons in the weaker of the two bonds are
shared laterally or sideways while those in the
stronger bond are shared in a head-on manner.
The electrons can
