| 英文摘要 | Marine sensors are crucial for marine environment monitoring, yet biofouling can severely degrade their performance. Existing antifouling strategies exhibit numerous limitations, necessitating novel, durable, and environmentally friendly antifouling technologies. This study designed a three-dimensional model of a 6-stage Tesla valve-type channel antifouling tablet arranged in a 3 x 3 array. Computational fluid dynamics analyzed the valve's operational mechanism, and a valve channel featuring a shunt angle of alpha = 50 degrees was selected for experimental investigation. Antifouling tablets incorporating integrated Tesla valve-type channels were successfully fabricated via self-developed antifouling functional ink and digital light processing 3D printing. They have intact internal structure, high precision, and uniform antifouling active substance distribution. Compared to traditional designs, the Tesla valve-type channel antifouling tablets significantly reduced the initial burst release of antifouling agents and enhanced Cu2+ concentration during forward flow. After 60 days of dynamic seawater flushing, the Cu2+ release rate of the forward Tesla valve-type channel antifouling tablet was approximately three times that of the reverse Tesla valve-type channel. A 90-day antifouling evaluation in an actual marine revealed that the forward Tesla valve-type channel antifouling tablets exhibited the most effective antifouling performance, with a marine microorganism coverage rate of only approximately 2.03 %. Long-term indoor and outdoor testing confirmed the structure integrity of the valve, and analysis of weight loss and Cu elements content further substantiated the valve's diodicity. Overall, the Tesla valve structure effectively regulates the release of antifouling agent, targeting biofouling areas with precision and minimizing premature loss caused by reverse seawater influx. This innovative approach facilitates the on-demand, accurate, and sustained release of antifouling agents, paving the way for the long-term antifouling and 3D printing applications of marine sensors. |
