摘要
本工作报道了一种方便、快速地制备具有可控粘附性的有序多孔超疏水表面的方法。采用呼吸图法制备了高度有序的蜂窝状表面及相应针垫结构表面~([1])。先后利用多巴胺沉积、原位生产银纳米粒子并组装全氟癸硫醇对上述两种表面进行修饰,制得了具有高粘附反差的超疏水表面。结果表明,修饰后的蜂窝状表面对水滴是高粘附的,而针垫状表面则是低粘附的。通过组合设计蜂窝状与针垫状结构,制备了具有不同粘附力的图案化超疏水表面,从而实现了液滴的转移(图1)、运输(图2)与化学反应监测等多方面应用~([2])。
We here report a new strategy for fabricating superhydrophobic surfaces with tunable water adhesion. Highly ordered honeycomb porous films were prepared by the breath figure method. By simply removing the top surfaces of the honeycomb films, pincushion-like surfaces can be obtained. The adhesive force of a water droplet on the above-mentioned films can be adjusted in a wide range. We demonstrate the dramatically different adhesion behaviors on superhydrophobic honeycomb-patterned and pincushion-like surfaces. Furthermore, applications of the surfaces in various areas such as water transportation, manipulation, and chemical reaction monitoring are discussed.
