Abstract

For developing new marine non-toxic antifouling coating, it was investigated the luminescence property in seawater on long-life afterglow fluorescent coatings modified by nano-TiO₂. The influences of the content and crystalline microstructure of fluorescent powder, different binder resins of coating were studied on the luminescence characteristic of the coating. The results showed that fluorescent coatings modified by nano-TiO₂ represent the good luminescence characteristic in seawater. With the increase of the content of fluorescent and nano-TiO₂ powders in coating, the luminescence property of coating increases. As light afterglow time increases, the illuminance of both fluorescent powder and luminous coating decays exponentially. Compared with long-life afterglow fluorescent coatings not modified by nano-TiO₂, the afterglow illuminance of the coatings modified by nano-TiO₂ was remarkably improved. The luminescence property in seawater of the coating based on fluorocarbon resin is much more than that of the coating based on acrylate resin.
