3,4-Ethylenedioxythiophene is used as a monomer to synthesize the conductive polymers and used as a reductant in the one-pot synthesis of gold nanoparticles from chloroauric acid, as starting material used in palladium-catalyzed mono and bis-arylation reactions and in the synthesis of conjugated polymers and copolymers, with potential optical applications. It is also used in redox activity, electroactivity and conductivity.
1) the application in solid electrolytic capacitor
The electrolytic capacitor using PEDT as the negative pole is called solid conductive polymer capacitor. Its conductivity is 100S / CM, which is 100 times of TCNQ salt, 10,000 times of electrolyte.The security of solid conductive polymer capacitor is better, when it is in the high Temperature, the electrolyte is just melting but can not explode.
Compared with the traditional manganese dioxide solid electrolytic transistor electrode, the solid electrolytic capacitor electrode made by PEDT has the following characteristic.
2) the super material of capacitor electrode
PEDT as a new type of storage capacitor materials. The present experimental data indicate that the capacity of super capacitor using PEDT as electrode can achieve 3000 F. Recent research has concentrated on improving the polymer discharge performance, cycle life and thermal stability and so on.
3) The basic material of organic electroluminescence (OEL) display technology
Organic electroluminescence (OEL) display technology is a quite hot topic in recent years. PEDT can be as the hole injection layer of PLED, also can replace indium oxide or Tin oxide(ITO) conductive layer, therefore PEDT is the most important polymers of PLED technology in the future.
4) Other application
Moreover, as the fine characteristics of PEDT, it has broad applying prospects in Via PCB coating, sensors, rechargeable batteries, photodiode, corrosion protection.
PEDT and its derivatives are kinds of the polymer with good conductivity and high stability, It has been successfully applied in solid capacitors, antistatic coatings, organic electroluminescence and many other electronics industry area in recent years. It brought to the rapid development of conductive polymer, representing the development trend of conductive polymers. It will become the most important material of electronics and information industry in the future.
