Sptnws,

Thanks for responding to this. He lives in the past.

From that same article! DuPont has been active in developing this technology since 2000!!

"The properties of the materials are definitely limited by disorder," says Heeger, who in 1990 cofounded the company UNIAX, which was purchased by DuPont in 2000, to commercialize conducting polymers.

Looks like "stumbling" across conducting polymers is a common practice. ROTFLMAO!

A theme in the development of conducting polymers has been chemists' ingeniously capitalizing on mistakes. Both luck and insight played roles in the discovery of the first conducting polymer, a form of the material called polyacetylene.

I find this very interesting. Very interesting!

Orderly polymers
A different type of accident contributed to the discovery of a way to make a well-ordered, conducting polythiophene. In May 2000, Hong Meng, a student working in chemist Fred Wudl's laboratory at the University of California, Los Angeles, made a sample of a thiophene monomer known as 2,5-dibromo-3,4-ethylenedioxythiophene and sealed it in a jar. In March 2002, when Meng retrieved the jar, he discovered that the white crystalline powder he'd prepared now looked like shiny, black crystals. Because Wudl's lab studies conducting polymers, it has a rule that any metallic-appearing material that a researcher makes or finds must be tested for electrical conductivity.

Where is the patent for the material, ElectriPlast? That was the point. Until there is a patent on ElectriPlast, those other patents are not even worth the cost of a license ($1). Some of us get it!!
