Research on Anti-biofouling Capacity of the Acrylic Resin Coating Contained Polyaniline-CuO Composite Nanoparticles

As human marine activities increases and marine economic industry develops, the harm and loss caused by marine biological fouling are becoming more prominent, mainly manifested in rasing CO2 emissions, affecting the safety of ships and underwater infrastructures, and hindering marine economic activities. In order to protect the marine ecological health, maintain the marine environment and reduce the impact of marine biological fouling on ship operation and marine safety, polyaniline CuO composite nano particles were synthesized by chemical method, and the toxicity of barnacle and the anti adhesion of diatom were tested in this paper. The toxicity experiment of barnacle confirmed that when the concentration of polyaniline CuO composite nanoparticles was 4 mg / L, the 24-hour mortality rate of barnacle reached 95%; The indoor hanging board experiment shows that the anti adhesion rate of polyaniline CuO composite nano acrylic coating to diatom is 89.5% after 75 days of indoor hanging board. This showed that polyaniline CuO composite nano has good anti biological fouling effect. At the same time, as an environment-friendly anti fouling agent, it has a good application prospect in anti marine biological fouling.
