Abstract (en)
[origin: WO2022129317A1] The present invention relates to the use of a polymer of hyaluronic acid modified by the grafting thereto of at least one of the functions - SO3 and aromatic rings, as dopant for a polymer formed from one or monomers chosen from EDOT, ProDOT and derivatives thereof. It also relates to an aqueous suspension, or ink, and materials, in particular hydrogels, based on at least one PEDOT and/or PProDOT polymer doped by at least one modified hyaluronic acid polymer according to the invention, and to methods for preparing same, and also to the use thereof in bioelectronic or biosensor devices.
