超疏水纳米界面材料的制备与表征
首发时间:2010-09-27
摘要:近几年来,与水的接触角大于150 的超疏水表面引起了极大的观注,因为它在自清洁材料,以及生物材料等许多领域有着及其重要的应用前景。仿生超疏水性表面的研究是化学模拟生物体系研究中的一个新领域。本实验是在仿生超疏水表面研究的基础上,用NaOH溶液处理锌表面,控制反应的时间,温度与溶液的浓度等条件,在工程技术材料表面构建出微米纳米相结合的类似荷叶表面的微观结构。再修饰低表面自由能的石蜡的CS2溶液薄膜层,使锌表面的接触角达到152 ±1。

Preparation and Characterization of Super-Hydrophobic Nanoscale Interfacial Materials
Abstract:In the past years , superhydrophobic surfaces with water contact angles large than 150 have received a lot of research attention , Due to their important appliations ranging from self-cleaning materials to microfluidic devices and biomaterials . Biomimic super-hydrophobic surface has been considered as a new research field in mimicing biologicalsystems with chemistry .Base on biomimic super-hydrophobic surface . Use sodium hydroxide (NaOH) deal with Zinc (Zn) surface .By controlling the reaction of time . temperature , and concentration solution . The fundamental mechanism of engineering material zinc(Zn).surface that a combination of a hierarchical micro/nanostructure and surface structure similar to hydrophobic structure of lotus leaf . then decorate it with CS2. the contact angles has rise to a super-hydrophobic surface with 152±1.
Keywords: hydrophobic contact angle micro/nanostructures
