Highlights•PFAS-free hydrophobic coating with corrosion, fouling, and condensation durability•Scalable cost-effective methodology for versatile applications•Standard ASTM tests used evaluating mechanical chemical robustness•50% enhancement of the steam heat transfer coefficientSummaryCorrosion metal components is a long-standing problem in many industries. While barrier coatings are commonly adopted solution, large-scale complex geometries non-trivial expensive. Furthermore, conventional anti-corrosion thick unfavorable thermal applications. Here, we develop scalable facile dip-and-flow method polydimethylsiloxane (PDMS) as thin durable coating. We demonstrate controllable implementation ranging thickness from 300 nm to 23 μm. Corrosion fouling durability demonstrated under acidified seawater spray (ASTM G85-A3 standard) realistic particulate saltwater flow conditions loop. Given its intrinsic hydrophobicity low contact angle hysteresis, 500-nm-thick PDMS-coated substrates exhibit dropwise condensation, demonstrating 50% higher coefficient compared filmwise on uncoated Cu. This work demonstrates facile, coatings, while holistically energy applications.Graphical abstract

The extended immersion of ships in seawater frequently results biofouling, a condition characterized by the accumulation marine organisms such as barnacles and algae. To combat this issue, application anti-fouling coatings to hull surfaces vessels has emerged one most effective strategies. In response increasing global emphasis on environmental sustainability, there is growing demand for that not only demonstrate superior efficacy but also adhere stringent standards. traditional use organotin-based self-polishing coatings, known their high toxicity, been prohibited due concerns. Consequently, progressive shift toward development environmentally friendly coatings. This paper reviews toxicity limitations associated with conventional It provides comprehensive overview recent advancements field, including novel low surface energy biomimetic nanostructured each leveraging distinct mechanisms. evaluates composition performance these emerging identifies key technical challenges remain unresolved. proposes multi-faceted approach addressing challenges, suggesting potential solutions enhancing effectiveness compatibility technologies. forecasts future research directions trajectories emphasizing need continued innovation achieve both sustainability performance.
