Hideki Shirakawa: The Architect of Conductive Polymers
The Discovery that Sparked a Revolution
Hideki Shirakawa, a Japanese chemist, engineer, and Professor Emeritus at the University of Tsukuba and Zhejiang University, is renowned for his groundbreaking discovery of conductive polymers. This pioneering work, which earned him the Nobel Prize in Chemistry in 2000, has transformed the field of materials science and has far-reaching implications for technology and innovation.
The Early Years and Education
Born on August 20, 1936, in Tokyo, Japan, Shirakawa was the second son of a military doctor. He spent his childhood in Manchukuo and Taiwan, before moving to Takayama, Gifu, his mother's hometown. Shirakawa graduated from Tokyo Institute of Technology (Tokyo Tech) with a Bachelor's degree in chemical engineering in 1961 and earned his doctorate in 1966. He began his academic career as an assistant in the Chemical Resources Laboratory at Tokyo Tech.
The Birth of Conductive Polymers
While working as an assistant at Tokyo Tech, Shirakawa developed polyacetylene, a polymer with a metallic appearance. This innovative material caught the attention of
Alan MacDiarmid, who visited Tokyo Tech in 1975. Shirakawa's work on polyacetylene led to an invitation to work in MacDiarmid's laboratory at the University of Pennsylvania as a postdoctoral fellow in 1976. Collaborating with MacDiarmid and American physicist Alan Heeger, Shirakawa discovered that doping polyacetylene with iodine vapor could significantly enhance its conductivity.
A Nobel Prize and a Legacy
The discovery of conductive polymers led to Shirakawa, MacDiarmid, and Heeger being awarded the Nobel Prize in Chemistry in 2000. This recognition solidified Shirakawa's position as a leading figure in the field of materials science. His work has inspired new generations of researchers and has paved the way for the development of innovative materials and technologies.
Academic Career and Honors
Shirakawa's academic career spans over four decades, with notable positions at the University of Tsukuba and Zhejiang University. He became an assistant professor at the University of Tsukuba in 1979 and was promoted to full professor in 1982. In 1991, he was appointed as Tsukuba's Chief of Science and Engineering.
