水性聚氨酯防污涂料的海洋细菌附着实验

Adhesion of marine bacteria on three antifouling coatings based on waterborne polyurethane

利用平板计数法、扫描电镜等实验研究了海洋细菌在三种水性聚氨酯防污涂层上的附着.结果表明,PTFE和锐钛型纳米二氧化钛均对海洋细菌的附着有抑制作用.随着PTFE和锐钛型纳米二氧化钛在涂层配方中的含量增加,涂层防止海洋细菌附着的能力增强,并且二者协同作用时效果更好.

The adhesion of marine bacteria on three antifouling coatings based on waterborne polyurethane was studied by using scanning electron microscope and Bactoscan FC. The results showed that both PTFE and nano - TiO2 in coatings could impede the adhesion of marine bacteria. The antifouling effect of the two additives becomes more remarkable when their content increases and when they are simultaneously used.
