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
Monomers, such as hydroxymethyl-3,4-ethylenedioxythiophene
(HM-EDOT), 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

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
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.
