  • Patent number: 7641977
    Abstract: Nonconjugated conductive polymers, which are all polymers that have a ratio of double bonds to total bonds of less than ½ are doped or used to produce compositions with unexpected characteristics in this invention. A light emitting structure can be produced by coating a quartz or glass substrate with a high work function metal which has a nonconjugated conductive polymer film on the metal and a low work function metal deposited on the nonconjugated polymer. The electrical conductivity of nonconjugated polymers can be greatly increased by doping the polymer with a dopant. The mechanical and elastomeric properties of a nonconjugated polymer can be changed by doping the polymer. The electro-optic effect and the refractive index of a nonconjugated conductive polymer can be greatly changed by doping the polymer. Among the nonconjugated polymers are styrene-butadiene-rubber (SBR), poly(?-pinene) and cis-1-4 polyisoprene.
