The accumulation of dead bacterial cells on the surface of general antibacterial and anti-corrosion coating will provide nutrition for subsequent cells, resulting in the rapid decomposition of the coating, which is the main factor restricting the service life of the coating. In this study, PDA was combined with PNIPAm to attain core-shell microspheres with thermoresponsive. Afterward, the modified scales were obtained by combining the pretreated basalt scales with core-shell microspheres and then depositing AgNPs. The thermoresponsive anti-corrosion and antibacterial composite coating were prepared by spraying. The results of cyclic immersion experiments at different temperatures showed that the coating prevented bacterial adhesion at 37 °C and removed adhesion bacteria at 4 °C. Concurrently, the coating realized the controlling release of the antibacterial agent through the temperature change. The EIS and SEM results indicated that the coating provided long-term protection for the matrix.

一般抗菌防腐涂层表面的死菌细胞堆积，会为后续细胞提供营养，导致涂层快速分解，是制约涂层使用寿命的主要因素。在这项研究中，PDA 与 PNIPAm 结合，获得了具有热响应性的核壳微球。然后，通过将预处理的玄武岩鳞片与核壳微球结合，然后沉积AgNPs，得到改性鳞片。热响应防腐抗菌采用喷涂法制备复合涂层。不同温度下的循环浸泡实验结果表明，涂​​层在37 ℃时可防止细菌粘附，4 ℃时可去除粘附细菌。同时，涂层通过温度变化实现了抗菌剂的控释。EIS 和 SEM 结果表明，涂​​层为基体提供了长期保护。
