![]() We further find that the antifouling PEDOT can tightly integrate with diverse substrates (Au, ITO, and stainless steel) this strengthening approach works effectively for all the tested three hydrophilic PEDOTs. Its wet lap shear strength with substrates is three times higher than the pristine PEDOT it can tolerate 20 h of sonication treatment in water, while the three control PEDOT electrodes all start to collapse within minutes. This antifouling conducting PEDOT electrode shows much enhanced interfacial adhesion with substrates and cohesion in water than all the other tested PEDOT conducting polymers. Here, we develop a durable conducting polymer electrode based on EDOT copolymers expressing zwitterionic phosphorylcholine and DOPA moieties, which enable low impedance communication, excellent protein/cell resistance, and long-term stable operation. However, the efforts to create stable and long-lasting conducting polymer electrodes are challenged by biofouling and the physical failure of electrodes. Conducting polymers are emerging as a very attractive type of electro-materials for bioelectronic devices, owing to their low impedance, high charge injection limit, and small modulus. ![]()
