As a vital platform for marine scientific research, the antifouling performance of a long-range research vessel's hull directly impacts the accuracy of scientific data and the efficiency of mission execution. Traditional chemical antifouling coatings, with their toxic release leading to sample contamination and equipment interference, can no longer meet the stringent requirements of modern marine research. Developed based on biomimetic principles, shark skin-inspired physical antifouling coatings offer a brand-new solution for research vessels through their unique micro-riblet structure.

Traditional antifouling coatings achieve their effect by continuously releasing biocides such as copper ions, a mechanism that causes multiple interferences with scientific research work. First, the released toxins contaminate the water surrounding the hull, directly affecting the purity of collected seawater samples and biological specimens, leading to distorted environmental monitoring data. Second, these chemical substances may corrode precision detection equipment installed on the hull, such as sonar and transducers, impairing their measurement accuracy and service life. Furthermore, chemical antifouling coatings typically need to be replaced every 3–4 years, potentially creating a gap in protection during long-term research missions, which allows biofouling to accumulate on the hull and compromises sailing performance.

The core advantages of this coating are reflected in three aspects: environmental friendliness, equipment compatibility, and long-term durability. Its completely non-toxic formula ensures no contamination of scientific samples, guaranteeing the authenticity of data. The physical mechanism avoids chemical corrosion and signal interference to precision instruments. With a protection cycle exceeding five years, it meets the demands of most research missions and significantly improves vessel operational availability. Particularly in environmentally sensitive regions such as polar research expeditions, its green and eco-friendly characteristics offer even greater advantages.

At present, this technology has been gradually applied to research vessel fleets. Practical applications have shown that research vessels equipped with this coating can keep their hulls clean throughout the entire mission cycle, ensuring sustained sailing efficiency and equipment stability. As the demand for data accuracy in marine scientific research continues to rise, this green antifouling technology is set to become the standard configuration for research vessels, providing more reliable technical support for ocean science studies.

Shark skin-inspired physical antifouling coating represents the future direction of hull antifouling technology. Its characteristics—environmental friendliness, equipment safety, and long-lasting protection—make it an ideal choice for research vessel antifouling. The widespread adoption of this technology will effectively enhance the quality and efficiency of marine scientific research, providing strong support for humanity’s exploration of ocean mysteries.
