Marine biological fouling is a persistent issue facing the marine industries, which not only causes damage to the underwater facilities but also results in substantial financial losses. Diatoms are one of the most harmful polluters in the ocean. In this paper, novel antifouling coatings inspired by fluorescent coral were reported. Waterproof long afterglow phosphors (WLAP) were introduced into the cross-linked network of polydimethylsiloxane (PDMS). WLAP can absorb and store light energy during the day and emit weak fluorescence at night, which affects the normal physiological activities of diatoms. Through the synergistic mechanism of low surface energy and fluorescence antifouling, excellent antifouling performance is achieved throughout the day. The settlement behavior of Navicula sp. on WLAP/PDMS composite coatings was studied under simulative diurnal alternation, continuous light, and dark conditions. The results demonstrated that the adhesion of diatoms on WLAP/PDMS composite coatings decreased significantly under simulative diurnal alternation. The inhibition effect of the sky-blue composite coating was the most obvious. The attachment reduction rate (ARR) was 35.4% compared with the blank control coating, and the diatom removal rate (DRR) after washing was 42.3%. Constant light conditions also affect the normal physiological activities of diatoms, while the feeble light of coatings is covered. In continuous dark condition, the antifouling abilities of coatings mainly depend on their low surface energy. The composite waterborne coatings prepared in this research is non-toxic and eco-friendly and can recycle solar energy, which supply a new direction for enhancing the static antifouling ability of coatings and an environmentally friendly antifouling strategy, and becomes an important step for sustainable development.

海洋生物污染是海洋工业面临的一个长期存在的问题，它不仅对水下设施造成损害，而且造成巨大的经济损失。硅藻是海洋中最有害的污染物之一。在本文中，报道了受荧光珊瑚启发的新型防污涂料。将防水长余辉荧光粉（WLAP）引入聚二甲基硅氧烷（PDMS）交联网络中。WLAP在白天能吸收并储存光能，在夜间发出微弱的荧光，影响硅藻的正常生理活动。通过低表面能与荧光防污的协同机制，实现全天优异的防污性能。舟形藻的沉降行为。在模拟昼夜交替、连续光照和黑暗条件下研究了 WLAP/PDMS 复合涂层的性能。结果表明，在模拟昼夜更替的情况下，硅藻在WLAP/PDMS复合涂层上的附着力显着下降。天蓝色复合涂层的缓蚀效果最明显。与空白对照涂料相比，附着减少率（ARR）为35.4%，清洗后硅藻去除率（DRR）为42.3%。恒定的光照条件也会影响硅藻的正常生理活动，而涂料的微弱光线则被掩盖。在连续黑暗条件下，涂层的防污能力主要取决于其低表面能。本研究制备的复合水性涂料无毒环保、可回收太阳能，为增强涂料的静电防污能力和环境友好的防污策略提供了新的方向，成为可持续发展的重要一步。
