摘要 研制了分别添加10%、20%、30%PTFE粉末的氟碳涂料,利用扫描电镜和表面形貌仪研究了涂层中PTFE含量对涂层表面形貌的影响,借助生物、体视显微镜和图像分析方法研究了涂层形貌对海洋底栖硅藻附着的影响。结果表明,随着氟碳涂层中PTFE含量的增加,涂层的表面粗糙度降低,涂层上底栖硅藻的附着量随之减少。底栖硅藻在水平放置涂层上的附着量远高于在竖立放置涂层上的附着量,并且更易于附着于表面存在微细缝隙的涂层上。这些结果为研发新型无毒低表面能防污涂料提供了实验和科学依据。 Fluorocarbon coatings were developed with respectively 10%,20% and 30% PTFE powder. Influence of content of PTFE on surface morphology of coatings was investigated using SEM and rugometer. It was studied that the effect of coating roughness on settlement of benthic diatom with biological microscope, stereo microscope and image process. Resuhs indicate that surface roughness of the coaling decreases and benthic diatom reduces attaching onto the coating with thc increase of content of PTFE in paint studied. Benthic diatoms attached much morc on horizontal specimen than on vertical ones, they tend to settle onto the surface of the coatings that there are lots of micro cracks in it. These results are helpful for developing new non toxic antifouling paints.
