Research and analysis on application of bionic coating technology based on nano-inorganic materials in water ecological protection and restoration

Abstract

[Objective] To evaluate the anti-fouling, anti-corrosion, and anti-biofouling performance of bionic coating technology in water ecological protection and restoration, and analyze its application effectiveness in complex water environments. [Methods] Multi-layer spraying technology was used to prepare the bionic coating, and its antibacterial performance, physical performance indicators, and safety indicators of water quality were tested to comprehensively evaluate the coating's protective ability in aquatic ecological environments. Combined with typical cases, the long-term stability and protective effect of the coating were verified. [Results] Bionic coating technology formed a dense protective layer on the surface through a multi-layer spraying process, demonstrating excellent performance in anti-fouling, anti-corrosion, and durability. The antibacterial rate exceeded 95%, VOC emissions were ≤23 g/L, and the coating remained stable in acidic, alkaline, and saline environments. Engineering applications showed that the anti-fouling rate was ≤2%, the cleaning and maintenance frequency was reduced by 1 to 3 times, and the service life of the facilities was significantly extended. [Conclusion] Bionic coating technology demonstrates excellent anti-fouling, anti-corrosion, and anti-biofouling capabilities in water ecological protection and restoration. It can effectively reduce biological pollution, extend the service life of facilities, lower maintenance costs, and provide an efficient and sustainable protection solution for hydraulic structures.
