PEDOT, or Poly (3,4-ethylenedioxythiophene), is a polymer mixture of two ionomers. PEDOT offers many benefits such as moderate band gap, low redox potential, and optical transparency in the conducting stage. This polymer is both an ionically- and electrically-conductive polymer, owing to the aforementioned properties. PEDOT finds a wide range of applications in various end-use industries, such as electronics, healthcare, and energy in the form of smart windows, capacitors, sensors, and antistatic packaging. Moreover, the increasing use of PEDOT can be attributed to their good conductivity and chemical stability.
PEDOT is a proprietary polymer blend of two organic monomers. One component in the blend is composed of sodium orthophosphate that is typically a phosphonate orthophosphate. Part of the orthophosphates are polymerized and carry a negative charge only. The other component is commonly known as the sulfate ester of sodium, which can be used for treating different types of stains. Sulfate ester solution can also act as a catalyst for the chemical reaction with a positive charge on one of the anions, enhancing catalytic activity of the other anions and ions.
