Example sentencesExamples
One such early material was AsF 5 doped cis polyacetylene - this was not a pleasant dopant to use, but it increased the polymer's conductivity by a factor of as much as 10 11.
In addition, certain polyacetylene constituents of Echinacea have been found to be bacteriostatic against E. coli and Pseudomonas aeruginosa.
Both luck and insight played roles in the discovery of the first conducting polymer, a form of the material called polyacetylene.
First, researchers found that when the polymer polyacetylene acquires an extra electron, the particle seems to split into two quasi-particles, or excitations of the molecule as a whole.
