The Nobel Prize in Chemistry for 2000 was given to Alan MacDiarmid, Alan Heeger, and Hideki Shirakawa for the discovery and development of electrically conductive polymers. 

Hideki Shirakawa was born in Tokyo on August 20, 1936. He was the third of five children born to Hatsutarou Shirakawa, a physician, and his wife, Fuyuno Shirakawa. In the first dozen years of his life, Hideki Shirakawa moved frequently with his family, first to the rural city of Takayama, then to the province of Manchu on the Chinese mainland (then recently conquered by the Japanese army), and finally backto Tokyo and Takayama after the end of World War II. As early as junior high school, Shirakawa was thinking about a career in the field of polymers. He wrote an essay in which he expressed a desire to "conduct research on plastics useful for ordinary people."... 

Alan Heeger and Hideki Shirakawa in the mid 1970s, resulted in their sharing the Nobel Prize in chemistry in 2000.

In 1958, polyacetylene was first synthesised by Natta et al. as a black powder. This was found to be a semi-conductor with a conductivity between 7 10 n to 7 10"3 Sm 1, depending upon how the polymer was processed and manipulated. This compound remained a scientific curiosity until 1967, when a post-graduate student of Hideki Shirakawa at the Tokyo Institute of Technology was attempting to synthesise polyacetylene and a silvery thin film was produced as a result of a mistake. 

A graduate student in Hideki Shirakawa s laboratory at the Tokyo Institute of Technology was trying to make a polymer called polyacetylene from ordinary acetylene welding gas. The polymer, a dark powder, had first been synthesized in 1955, but no one knew much about it. Instead of a dark powder, Shirakawa s student produced a lustrous, silvery film that looked like aluminum foil but stretched like Saran wrap. Looking back over his chemical recipe, the student saw his...
