| 摘要: |
| 借鉴海洋生物表皮具有天然的防污特性，通过“生物原样PDMS模板目标涂层”的制备过程，实现了表面具有甲鱼壳仿生织构正负形貌的有机硅改性丙烯酸酯涂层的制备。系统考察了仿甲鱼壳正负形貌织构涂层的表面形貌、润湿性、对蛋白质的抗吸附能力、对舟形藻和新月藻的防污性能。结果表明：仿甲鱼壳正负形貌织构化涂层表面存在类似颗粒状的突起，表面疏水性增强，与空白涂层相比，可使蛋白质、舟形藻和新月藻的附着量分别降低58%、69%、50%和46%、52%、53%，由此可以看出，正负形貌涂层对蛋白质和2种藻类的防污效果略有差异。仿甲鱼壳涂层具有较好的防污效果，究其原因，与其表面存在的微观形貌有着很大的关系。 |

| Abstract: |
| Inspired by the unique antibiofouling performances of ocean lives, the silicone modified acrylic resin coatings with turtle bionic textures were successfully prepared by the process of “biological samplePDMS templatetarget coating”. The surface morphology, wet/dewetting, antifouling properties of the coatings with positive/negative turtle morphologies against bovine serum albumin (BSA) protein, the Navicula and Closterium were investigated. The results showed that there are irregular bumps on the surface of the coatings, and the coatings with positive/negative turtle morphologies can reduce the amount of BSA, Navicula and Closterium attached to the coatings by 58%, 69%, 50% and 46%, 52%, 53%, respectively, compared with control coatings. However, they display different antifouling effects. The coatings with turtle textures display good antifouling performance and this is closely related to the micro morphology on the surface of coatings. |
