| 1 | Wetting Transition from Hydrophilic to Superhydrophobic over Dendrite Copper Leaves Grown on Steel Meshes显示文摘With the development of water purification technologies,the usage of superhydrophobic meshes is increased but the fabrication of durable and cost effective superhydrophobic meshes is still challenging.Here,the formation of hierarchical copper fractals on stainless steel meshes and their superhydrophobicity without any physical or chemical modification were studied.In addition,the improvement of superhydrophobicity of surfaces during storing in a glass bottle for a long time(>one year)is reported.The structures were prepared using electrodeposition method applying cyclic voltammetry and square pulse deposition approaches on stainless steel meshes with 50μm,100μm and 200μm pore sizes.The prepared layers are a composition of copper with varying amounts of cuprite(Cu20)depending on deposition method and mesh pore size.As-prepared cyclic voltammetry layer on 100μm mesh showed the parahydrophobicity with the contact angle of 154°but a large sliding angle.The one-year stored samples in the glass bottle showed superhydrophobicity with the contact angles larger than 150°and sliding angles in the range of 4°-20°.The observed improvement of superhydrophobicity is a great success in the realm of industrial water purification,while most other proposed samples by the others have problems related to the durability of superhydrophobicity. | Raziyeh Akbari Guilhem Godeau Mohammadreza Mohammadizadeh Frederic Guittard Thierry Darmanin | 2019 | Journal of Bionic Engineering2019，16，4： | 1 |
| 2 | Nanoparticles Covered Surfaces for Post-functionalization with Aromatic Groups to Obtain Parahydrophobic Surface with High Water Adhesion (Petal Effect)显示文摘众多的非凡的性质能在自然被观察。在这些性质之中, parahydrophobic 特征具有兴趣。这个性质与象玫瑰花瓣或壁虎脚那样的水与高粘附描述材料。这种表面在收获系统的水的域里为应用程序介绍一个真实潜力。在这个工作,我们报导新合成策略模仿这个性质。这里,我们在一个联合三策略。首先,单体是 electropolymerized 以便形成开始结构化的表面。然后, nanoparticles 是表面上的 grafted 增加 structuration 并且因而创造反应表面。最后, grafted 表面与各种各样的芳基炔属羟是 post-functionalized (Huisgen 反应) 控制表面化学和能量。这策略允许与两个很高恐水病的性质到达表面(= 140 ?????????????? 佒 ?? ???????????????? 瘠瑩潲吗?? | Guilhem Godeau Marek Dovcik Frederic Guittard Thierry Darmanin | 2017 | Journal of Bionic Engineering2017，14，3： | 0 |
