Dispersions Comprising Polythiophenes With A Defined Content Of Thiophene Monomer

Patent No. EP2627712 (titled "Dispersions Comprising Polythiophenes With A Defined Content Of Thiophene Monomer") was filed by Heraeus Deutschland on Oct 7, 2011. The application was issued on Aug 2, 2017.

Patent Summary

A method for producing a stable conductive polymer dispersion comprising polythiophene, particularly PEDOT/PSS, with reduced gelation tendency. The method involves oxidative polymerization of thiophene monomers, followed by partial removal of the reduction product, and optionally incorporating a controlled amount of residual thiophene monomer. The resulting dispersion exhibits improved stability and uniformity, enabling its use in applications such as flexible touch panels and electronic components.
