The manufacture and preliminary testing of a drag-reducing riblet texture with fouling-control properties is presented. The commercial fouling-release product Intersleek® 1100SR was modified to manufacture riblet-textured coatings with an embossing technology. Hydrodynamic drag measurements in a Taylor-Couette set-up showed that the modified Intersleek® riblets reduced drag by up to 6% compared to a smooth surface. Barnacle settlement assays demonstrated that the riblets did not substantially reduce the ability of Intersleek® 1100SR to prevent fouling by cyprids of Balanus amphitrite. Diatom adhesion tests revealed significantly higher diatom attachment on the riblet surface compared to smooth Intersleek® 1100SR. However, after exposure to flow, the final cell density was similar to the smooth surface. Statically immersed panels in natural seawater showed an increase of biofilm cover due to the riblets. However, the release of semi-natural biofilms grown in a multi-species biofilm culturing reactor was largely unaffected by the presence of a riblet texture.
介绍了一种具有防污性能的减阻微肋纹理的制造及初步测试。对商用防污释放产品Intersleek® 1100SR进行改性，采用压花技术制造微肋纹理涂层。在泰勒-库埃特装置中进行的流体动力学阻力测量表明，与光滑表面相比，改性后的Intersleek®微肋可使阻力降低高达6%。藤壶附着试验表明，微肋并未显著降低Intersleek® 1100SR防止纹藤壶无节幼体附着的能力。硅藻附着试验显示，与光滑的Intersleek® 1100SR相比，硅藻在微肋表面的附着明显更多。然而，在经过水流作用后，最终的细胞密度与光滑表面相似。在天然海水中静态浸泡的平板显示，由于微肋的存在，生物膜覆盖面积增加。然而，在多物种生物膜培养反应器中生长的半天然生物膜的释放基本不受微肋纹理的影响。
