Material scientists often look to biology for new engineering solutions to materials science problems. For example, unique surface characteristics of rice leaves and butterfly wings combine the shark skin (antifouling) and lotus leaf (self-cleaning) effects, producing the so-called rice and butterfly wing effect. In this paper, we study antifouling properties of four microstructured surfaces inspired by rice leaves and fabricated with photolithography and hot embossing techniques. Anti-biofouling effectiveness is determined with bioassays using Escherichia coli whilst inorganic fouling with simulated dirt particles. Antifouling data are presented to understand the role of surface geometrical features resistance to fouling. Conceptual modeling provides design guidance when developing novel antifouling surfaces for applications in the medical, marine, and industrial fields.
材料科学家经常从生物学中寻找新材料科学问题的工程解决方案。例如,水稻叶片和蝴蝶翅膀的独特表面特性结合了鲨鱼皮(防污)和荷叶(自清洁)的效果,产生了所谓的稻叶和蝴蝶翅膀效应。在本文中,我们研究了受稻叶启发并通过光刻和热压印技术制造的四种微结构表面的防污特性。使用大肠杆菌进行生物测定来确定抗生物污损的有效性,而使用模拟污垢颗粒来确定无机污损。提供防污数据以了解表面几何特征对防污的作用。概念建模为开发用于医疗、海洋和工业领域的新型防污表面提供了设计指导。
