Polymer Electronic System

Main Polymers molecules formed of many identical units, bond to each other into long chains. For a polymer to be electrically conductive it must imitate a metal – the electrons in the bonds must be freely mobile and not bound fast to the atoms. In 2000 Alan Heeger, Alan MacDiarmid and Hideki Shirakawa were awarded the Nobel Prize in Chemistry for showing how polymer can be made to conduct electric current. One condition for this is that the polymer should consist of alternate single and double bonds, termed conjugated double bonds. At present, the electronic world is very much dominated by inorganic materials, in particular silicon. The Nobel Prize hasn’t been a milestone in the progress of polymer electronics, but it showed the importance of this branch of knowledge. New word, “polymer” has appeared in electronic vocabulary as a short name of this knowledge and quickly developed technology
