(MENAFN- Coherent Market Insights) PEDOT, or Poly(3,4-ethylenedioxythiophene), is a conductive polymer used in a wide range of applications such as touch panels, capacitors, antistatics, printed electronics, organic solar cells, and organic light emitting diodes. This polymer offers several advantages such as low redox potential, moderate band gap, and optical transparency in the conducting stage. PEDOT is both an ionically- and electrically-conductive polymer, due to aforementioned properties, and thus find applications in various sectors, such as healthcare, energy, and electronics in the form of smart windows, capacitors, sensors, and antistatic packaging among others. Chemical stability and good conductivity is contributing towards the increase in adoption of PEDOT.

Today, technologically advanced products are manufactured using PEDOT polymers due to its electrical, optical and physicomechanical properties. PEDOT is a highly important, conductive polymer and is commercially available in organic electronics, electronic and electrochemical chemo-sensors, owing to its unique properties such as excellent chemical and electrochemical stability, high/controllable conductivity, high solution-fabrication capability and miscibility, and good optical transparency and biocompatibility. Some PEDOTs also have anti-corrosion properties and can resist UV light.

PEDOTs are considered safe, non-toxic, environmentally friendly, and low cost. They can be used to improve the electrical conductivity, mechanical performance, and thermal conductivity of a certain type of materials. PEDOTs are usually added together in the production process to obtain the desired properties. They are also used for the production of solar cells. They convert sunlight into electricity. In order to create solar cells, the surface area of a crystalline material must be increased in an appreciable amount. Solvent-based PEDOTs and hydrophobic (water-free) PEDOTs are commonly used in the manufacture of solar cells.

PEDOT is a proprietary polymer mix 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.

PEDOT has interesting features such as good electrochromic properties, small redox potential, low price, easy processability, good transparency, and satisfactory conductivity, among others. PEDOT is the most promising derivative of polythiophene, as it offers chemical and physical stability, biocompatibility, conductivity, and transparency. It is usually paired with polystyrene sulfonate (PSS) to enhance its molecular weight. The widespread use of conducting polymers, especially PEDOT, Poly(3,4-ethylenedioxythiophene), within the space of bioelectronics has enabled improvements, both in terms of electrochemistry and functional versatility.

The main property of PEDOT that ensures its unique place among conducting polymers is its high and stable electrical conductivity. Among the polymers used for chemo-sensors, PEDOT exhibits a relatively high stability and adjustable conductivity compared to polypyrrole (PPy) and polyaniline (PANI). Thus, there is an increasing demand for PEDOT in the electronics and healthcare industries. The growing adoption of PEDOT can be acknowledged through the numerous applications in bioelectronics, transparent electrodes, technical coatings, sensing, lighting, photovoltaics, and thermoelectricity, so forth.
