Bio-Inspired Surfaces for Fouling Resistance, Their Applications, Challenges, and Opportunities

Bio-inspired surfaces are developed to combat the unwanted buildup of substances like sediment, scale, or biological organisms on equipment and surfaces across various industries. This discussion encompasses various types of fouling, categorized by Young's modulus into hard and soft, and delves into crucial factors such as surface energy and wettability, which are essential for material development. We have identified a range of anti-fouling techniques from nature, inspiring the creation of synthetic surfaces based on these models. Despite these innovations, challenges such as durability, cost, and effectiveness against a broad spectrum of fouling organisms remain. To address these issues comprehensively, a strategy that integrates both mechanical properties and chemical treatments is essential, enhancing the performance and longevity of these bio-inspired surfaces.
