为了研发新型无毒舰船防污涂料,以FEVE氟碳树脂为成膜物、纳米TiO_2粉末为功能添加剂,试制了系列Nano-TiO_2/FEVE氟碳涂层,研究了纳米TiO_2含量对大型藻(水云藻)附着行为的影响.结果表明,水云藻的附着量随着涂层中纳米TiO_2含量的增加而减少,当纳米TiO_2含量达到0.8 %时,水云藻附着量降至最少,纳米TiO_2含量由0.8 %增大至2 %,水云藻的附着量增大,纳米TiO_2含量继续增大至4 %,涂层上水云藻的附着量反而减小.纳米TiO_2对水云藻的附着具有明显的阻止作用,可以成为一种安全环保的防污功能添加剂.

For developing new non-toxic antifouling paint, nano-TiO_2/FEVE fluoro-carbon coatings were prepared with content of nano-TiO_2 0.2 %, 0.4 %, 0.6%, 0.8 %, 1%, 2 %, 3 %, and 4 % respectively. The settlement tests of Ectocarpus (a macro-algae) on these coatings were investigated at 15±1℃ with a light-dark cycle of 12:12 hours. The chlorophyll a and fraction of Ectocarpus attached on coatings were estimated by using spectrophotometer, microscope and image processing. The results showe that the content of nano-TiO_2 in paints influence evidently the settlement of Ectocarpus. The chlorophyll a and fraction of Ectocarpus attached on coatings presents the same correlation with the content of nano-TiO_2. When the content of nano-TiO_2 increases from 0.2 % to 0.8 %, the amount of Ectocarpus attached on coating decreases until lowest point. The amount of Ectocarpus attached on coating increases with increasing the content of nano-TiO_2 from 0.8 % to 2 %. The amount of Ectocarpus attached on coating reduces again when the content of nano-TiO_2 increase from 2 % to 4 %. The results indicate that nano-TiO_2 may be a non-toxic and safe antifoulant for marine antifouling coatings.
