Novel highly stable conductive polymer composite PEDOT:DBSA for bioelectronic applications

Abstract In this work, a novel conductive polymer composite consisting of poly(3,4-ethylenedioxythiophene) doped with dodecylbenzenesulfonic acid (PEDOT:DBSA) for bioelectronic applications was prepared and optimized. The PEDOT:DBSA possesses superior biocompatibility toward cell culture electrical characteristics comparable to the widely used PEDOT:PSS. cross-linking processes induced by cross-linker glycidoxypropyltrimethoxysilane (GOPS), which investigated in detail using Fourier transform Raman spectroscopy XPS analysis, lead excellent long-term stability thin films aqueous solutions, even without treatment at high temperature. respect level were studied detail. conductivity significantly improved sulfuric posttreatment. A model transistor device based on shows typical behavior suitable properties or those available polymers bioelectronics, such as Based these properties, newly developed material is well suited that require contact living organisms, wearable implantable bioelectronics.
