Abstract Scope |
Biofilm formation is beneficial in a diverse range of chemical and environmental engineering applications, such as wastewater treatment, bioelectrosynthesis, and bioelectrochemical technologies, such as microbial fuel cells. The latter technologies depend on the direct utilization of electrons by microbes on an electrode surface to produce electricity or chemicals. Commonly, applying surface coatings to technologically relevant materials is done to increase material-microbe interactions. Unfortunately, many of these surface coatings are expensive and difficult to scale for industrial applications. Here, we present the use of an inexpensive surface-eroding, methacrylic-anhydride-based oligomer coating to improve initial cell attachment and uniform biofilm formation. The surface-eroding oligomers chemically degrade in the presence of water, leaving the matured biofilm on the relevant material surface. This work aims to explore the changes in biofilm formation as a function of the erosion rate of the methacrylic-anhydride coating using copper foils that are blade-coated with different formulation chemistries and thicknesses. |
