Künstliche dreidimensionale Biotope mit elektroaktiven Bakterien für hocheffiziente mikrobielle Brennstoffzellen durch Verwendung von Metall/Polymerfaser Hybridstrukturen
Polymermaterialien
Zusammenfassung der Projektergebnisse
In this project we: gained fundamental insides into the enhancement of extracellular electron transfer processes in electroactive biofilms by microbial copper sulphide formation; transferred this bio-inorganic hybrid structure concept towards the development of inexpensive, high-performance electrode materials based on CuS modified graphite; gained systematic insights into the impact of micro- and macrostructural surface elements of biofilm electrodes on the formation and performance of anodic, electrochemically active biofilms; developed a model for the description and development of optimal geometries of 3D flowthrough biofilm electrodes; developed flexible highly electroconductive composite nonwovens by wet-laid process; probed AgNW containing composite nonwovens for MFC; achieved wet-laid composite nonwovens with functional microbes.
