In some cases, light emission is observed when a voltage is applied to a thin layer of a conductive organic polymer film. It has led to the development of flat panel displays using OLEDs, solar panels and optical amplifiers.
Conductivity in conjugated polymers can be increased by photoconductivity, oxidizing or reducing the polymer with a "dopant" (though unlike typical dopants, large amounts are used, on the order of 1:4 to 1:2 dopants per monomer unit). This increase in conductivity can also be accomplished in a field effect transistor (organic FET or OFET).
The conductivepolymers obtained can be used in the electrical industry for the production of solar cells, for the conversion and fixing of radiation and for the production of electrical and magnetic switches, as well as for the antistatic treatment of plastics.
The polymers prepared by the process according to the invention are soluble and have intrinsic viscosities of [.eta.]>0.5, ie.
The electrically conductivepolymers prepared according to the invention and having conductivities greater than 10.sup.-2 S/cm may be used for the antistatic treatment of plastics, for the production of solar cells, for the conversion and fixing of radiation and for the production of electrical and magnetic switches.
The major objective of this report is to analyze electroactive, or conductive, polymers both inherently conductivepolymers (ICPs) and traditional conductively filled thermoplastics in terms of their competitive scenario in specific applications.
Conductiveplastics are made from traditional thermoplastics containing fillers that render them conductive, while ICPs conduct electricity on their own, and electro-optic polymers develop optical characteristics under influence of an applied electric field.
Although conductiveplastics mimic conductivity of metals (particularly copper and steel), insulative resins employing a conductive filler (e.g., metal or carbon powder, or fiber) achieve a measure of conductivity.
