Conjugated Polymers: An Introduction and Their Applications

The accidental discovering of semiconductive polyacetylene by Heeger، MacDiarmid and Shirakawa – who were granted the Nobel Prize – a new field arised in the class of polymers that is called “conducting polymers”. In this paper we discuss conjugated polymers which are semiconductors and become conducting polymers by doping that، conductivity of some of them are as good as copper. Conducting polymers، due to unique conductivity and electroactivity properties and optical properties (in some)، have several applications. For example they can be used in medical industries، military industries، electronics and etc. In this paper it was attempted to briefly describe the history of synthesis of these polymers، their structures، ways of doping and some of their applications.
