单词	polyacetylene
释义	polyacetylene /ˌpɒlɪəˈsɛtɪliːn / noun [mass noun] Chemistry A black electrically conducting solid which is a hydrocarbon polymer containing chains of carbon atoms joined by alternate double and single bonds.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.... Both luck and insight played roles in the discovery of the first conducting polymer, a form of the material called polyacetylene. 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.
