Antifouling surfaces are interest due to their wide range of applications in marine industry, medical implants, biosensors, water filtration, etc. The surfaces derived from surface active block copolymers (SABCs) having an amphiphilic groups have been developed. The surfaces were examined using dynamic water contact angle, captive air-bubble contact angle, atomic force microscopy, X-ray photoelectron spectroscopy and near edge X-ray absorption fine structure analysis. The resulting surface exhibits a very low contact angle and good antifouling properties that are very different from triblock copolymer precursor. The surfaces are strongly resistant to protein adsorption using bovine serum albumin (BSA) as a standard protein challenge. Biofouling assays with sporelings of the green alga Ulva and cells of the diatom Navicula showed adhesion was significantly reduced relative to a PDMS standard as well as to the triblock copolymer precursor of the SABCs. |
