Mixed Ionic-Electronic conductors (MIECs) are materials that can transport and couple both ionic and electronic charges. This is the key to develop devices for several applications, ranging from bioelectronics to energy storage. Our research aims to develop materials integrating sustainable and/or biodegradable building blocks, and post-synthesis processing methods to improve state-of-the-art bioelectronics. We are also focusing on developing green synthesis routes for MIECs, such as enzymatic polymerization.
In one of our works, we blended semiconductors with insulating polymers to improve their mixed ionic/electronic conductivity without modifying their chemical structure. The method has been used to improve the performance of bioelectronic devices while minimizing materials´ costs and environmental impact.
