Surfaces of sensors, underwater windows, underwater lights, and camera systems are important tools for remote maintenance, inspection and applications of maritime technologies. They are thus also a primary factor in occupational and operational safety in sea. In the maritime environment, such surfaces are confronted with fouling, bio-fouling, contamination, e.g. by sedimentation. In order to restore the functionality of optical systems, in a few hours, days or weeks of operation under fouling load, cleaning requires a great deal of personnel, time and economic effort, especially for ships and platforms.
Our research goal is therefore the development of a robust, actively self-cleaning antifouling systems for glasses, sensors, lights and cameras based on an electrodynamic process with low power demand.
In the subproject at the Institute of Water Chemistry, the microbiome and the contained elements of test waters as well as the composition and cell viability of the formed biofilms will be analysed and evaluated. This will also allow the environmental compatibility of the layers to be demonstrated. In addition, the impact on the antifouling coatings by varied environmental conditions (temperature, salinity, organisms) will be evaluated.
