Novel amphiphilic ABCBA pentablock copolymers were synthesized via ATRP. The presence of a central siloxane block allowed for dispersion of the copolymers in a crosslinked PDMS matrix in various loadings. Inclusion of the copolymer in the PDMS-matrix coatings enhanced the HSA and calf serum protein adsorption and decreased the adhesion strength of the sporelings of fouling macroalga Ulva linza. Biological results point to a potential of these systems as fouling release coatings.
