Inspired by the antifouling strategies of fluorescent corals and Gulf parrotfish, a novel polydimethylsiloxane (PDMS)–phosphor–silicone rubber sandwich‐structure coating is fabricated for combating biofouling. The coatings can emit weak light during night hours and have hydrophilic surfaces. The effectiveness of the coatings against various algae and bacteria, namely, Chlorella, Nitzschia closterium f. minutissima, gram‐negative Paracoccus pantotrophus, and gram‐positive Bacillus subtili is investigated. The results show that the PDMS–phosphor–silicone rubber sandwich‐structure coatings have broad‐spectrum antifouling performances. The results also demonstrate that surface hydrophilicity can effectively reduce adhesion of algae and bacteria, and that fluorescence inhibits only algae. In addition, the effect is revealed of the wavelength of different colored phosphor layers on antifouling capability to resist Chlorella and N. closterium f. minutissima. Blue (427 nm), yellow (663 nm), and red (731 nm) phosphor layers are conducive to combating Chlorella and N. closterium f. minutissima, whereas the green (512 nm) phosphor layer shows no distinct effect on resisting Chlorella and N. closterium f. minutissima. These findings can contribute to the development of new antifouling coatings. In addition, the antifouling capabilities of these coatings have potential for further improvement and development. The sandwich‐structure materials fabricated in this study should prove very useful in practical applications.

受生物启发的PDMS –荧光粉–硅橡胶夹心结构涂料，用于抗生物污垢
受荧光珊瑚和海湾鹦嘴鱼的防污策略的启发，制造了一种新型的聚二甲基硅氧烷（PDMS）-磷-硅橡胶夹层结构涂料来对抗生物污损。涂料在夜间会发出微弱的光，并具有亲水性表面。该涂层对各种藻类和细菌，即小球藻，纳茨菌（Nitzschia closterium） f的有效性。minutissima，革兰阴性副球菌和枯草芽孢杆菌阳性被调查。结果表明，PDMS-磷-硅橡胶夹层结构涂料具有广谱防污性能。结果还表明，表面亲水性可以有效减少藻类和细菌的粘附，并且荧光仅抑制藻类。另外，揭示了不同颜色的磷光体层的波长对抵抗小球藻和梭状芽胞杆菌f的防污能力的影响。Minutissima。蓝色（427 nm），黄色（663 nm）和红色（731 nm）荧光粉层有助于对抗小球藻和梭状芽胞杆菌f。minutissima，而绿色（512 nm）的荧光粉层对光阻没有明显的影响小球藻和梭状芽胞杆菌f。Minutissima。这些发现可有助于开发新型防污涂料。此外，这些涂料的防污能力还有进一步改进和发展的潜力。在这项研究中制造的夹层结构材料应被证明在实际应用中非常有用。
