In a recent study published in Progress in Organic Coatings (Volume 200, March 2025), researchers developed non-toxic, superhydrophobic nanocomposite coatings designed for marine antifouling applications. The novel materials are based on a PDMS-polyurethane (PDMS-PU) matrix filled with graphene oxide (GO) nanosheets decorated with tungsten disulphide (WS₂) nanorods. The hybrid GO-WS₂ structure enables enhanced surface roughness and dispersion, which in turn improves water repellency and fouling resistance. Superior antifouling and anticorrosion under biological stressThe coatings were tested against four common marine microorganisms—Kocuria rhizophila, Pseudomonas fluorescens, Aspergillus fumigatus, and Candida albicans—over a 30-day laboratory period. Non-toxic silicone-polyurethane nanocomposites filled with graphene/tungsten disulphide nanorods as hierarchical superhydrophobic marine antifouling surfaces, Progress in Organic Coatings, Volume 200, March 2025, 108987.
