General description

Aedotron polymers are solvent-dispersable forms of PEDOT. These are copolymers of doped PEDOT and a flexible, soluble polymer such as poly(ethylene glycol) (PEG). These colloidal dispersions are stabilized by the highly solvated PEG chains which sterically limit the aggregation of the PEDOT blocks. Aedotron polymers are neither acidic nor corrosive, it easily disperses in polar aprotic solvents.

Sheet resistance, spin cast thin films: 106-108 Ohms/sq

Average transmittance: 60-85%

General purpose, moderately conductive dispersion in chlorinated solvents


25 g in glass bottle


Conducting polymer dispersion suitable for making conducting films, anti-static layers and transparent electrodes. 1,2 Dichlorobenzene can be used to cast robust films on many polymeric substrates, but should be tested in each case.

Features and Benefits

The block copolymer structure renders the conducting polymer PEDOT highly dispersible in organic solvents. dichlorobenzene is compatible with many coatings and polymers formulations.

Other Notes

May settle over time. Must be sonicated before use
