Company Identification:Beili Chemicals (Zhangjiagang) Co., Ltd.
3,4-ethylene dioxythiophene, also known as 3,4-ethylenedioxythiophene, referred to as EDOT, colorless to pale yellow liquid, melting point of 10.5 ℃. Slightly soluble in water, 20 ℃ under the conditions of water solubility of 2.1g / L, a slight unpleasant odor.
Monomers, such as hydroxymethyl-3,4-ethylenedioxythiophene (HM), can be electropolymerized into a conducting polymer that is capable of a high rate of electron transfer, and can increase the flow of current on the electrode surface. HM-EDOT is a suitable monomer for this project because it has a hydroxyl functional group, which allows for increased solubility in aqueous environments. The monomer HM-EDOT can be functionalized and synthesized into carboxylic acid-3,4-ethylenedioxythiophene (COOH).

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 application in Antistatic coating
Antistatic coating is the most important application of PEDT. Compared with other conductive polymer, PEDT/PSS film is not easy to hydrolysis, and it is light fastness and is against high temperature. This kind of characteristic just satisfy the request of anti- static coating. In addition, the resistance of PEDT coating may reach 200 ~ 107 Omega /m2.Therefore, the anti-static coating mixed with PEDT has great potential development
3.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.
4.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.
Moreover, as the fine characteristics of PEDT, it has broad applying prospects in Via PCB coating, sensors, rechargeable batteries, photodiode, corrosion protection.
