Title: 3d Printing Technology Meets Marine Biofouling: A Study on Antifouling Resin for Protecting Marine Sensors
Abstract: Marine sensors are often subjected to biofouling, which can significantly decrease their sensitivity and lifespan. To combat this issue, various antifouling strategies have been proposed, taking into consideration the structural differences of different types of sensors. In this study, a novel antifouling 3D printing photosensitive resin was developed using acrylic photosensitive resin with controllable hydrolysis as a base material. Cu2O antifouling agents were dispersed within the base resin, resulting in an antifouling photosensitive resin with excellent dispersion properties. The photocured resin surface demonstrated good stability, minimal linear shrinkage, and the ability to print complex and high-precision physical components. The resin also exhibited excellent mechanical properties. Using the developed resin, a specific antifouling device for the sensing surface of a pH meter composite electrode was designed and 3D printed. The device effectively reduced the coverage of algae on the sensing surface, ensuring stable monitoring of the pH meter composite electrode for at least 1 month. Furthermore, the exudation rates of Cu2+ and Zn2+ within one month under static conditions of antifouling tablets were found to be reasonable. A specific antifouling device suitable for marine optical windows was also designed and printed using the developed resin. The present study reports on the development and evaluation of a device that effectively hinders the adhesion of marine organisms, thus improving the maximum underwater transmittance of glass surfaces in a real sea environment. This innovative antifouling approach holds significant promise for enhancing the performance of marine sensors used in sensing surfaces. Furthermore, this work highlights a novel application of 3D printing technology in the field of marine antifouling. Overall, these findings provide a valuable contribution to the scientific literature and have important implications for the development of more efficient and sustainable antifouling strategies in marine environments.
