Anitbiofouling is defined as the adsorption of biological life-forms and matter onto artifical surfaces. This adsorption of biological components can cuase huge problems like the increase of drag of ships by 80% which causes a comarable increase in fuel consumption.1 Current antibiofouling systems focus on the utilization of self-polishing layers, which release tinorganic compounds to poision the biological species, which introduces heavy metal and organic compounds into the water.2 Novel alternatives to this system mainly focus on the fouling release, in which surface energy and mechanical properties are minimized, however such approaches only work on vessels that regularly move.3 The presented poster shows the results of a systematical study of different PEM structures (hydrophilic, hydrophobic, nanoheterogenities, soft, hard, strong and weakly charged, positive or negatively terminated) and silicone rubber (PDMS) based on their antibiofouling properties in freshwater, their protein repulsion properties and their abilities for symbiotic biofouling.
