Abstract

Marine biofouling not only increases the navigation resistance of ships, accelerates the corrosion of metal substrates, but also hinders the healthy development of the marine economy. Inspired by the unique structure and function of Salvinia, we designed and fabricated biomimetic surfaces with superhydrophobic hairs and hydrophilic patches (SHHPs) using silicone rubber-graphene (SR-GN) and SR modified with polyacrylic acid (SR-PAA) composites. SHHPs can generate pinning effects underwater, forming an air layer as an environmentally friendly physical antifouling barrier. SHHPs exhibit strong capability in maintaining the air layer and can resist the attachment of bacteria and algae under static and simulated marine dynamic conditions. These results indicated that the physical antifouling strategy based on air layer provides a platform with broad application prospects for the maritime industry.

鼠尾草仿生材料水下空气层截留及防污性能研究

海洋生物污垢不仅增加了船舶的航行阻力，加速了金属基材的腐蚀，而且阻碍了海洋经济的健康发展。受Salvinia独特的结构和功能的启发，我们使用硅橡胶-石墨烯（SR- gn）和聚丙烯酸（SR- paa）改性的SR复合材料设计并制造了具有超疏水毛和亲水补丁（SHHPs）的仿生表面。SHHPs可以在水下产生钉住效应，形成一个空气层作为环保的物理防污屏障。shhp具有很强的维持空气层的能力，在静态和模拟海洋动态条件下都能抵抗细菌和藻类的附着。这些结果表明，基于空气层的物理防污策略为海运业提供了一个具有广阔应用前景的平台。

期刊介绍： Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields. Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication. The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
