我们提出了一种简便和廉价的超疏水聚合物涂层的方法。该方法包括在致孔溶剂的存在下原位聚合常见单体，以提供具有所需的微米级和纳米级粗糙度组合的超疏水表面。该方法适用于各种基底，并且不限于小面积或平坦表面。聚合材料可以研磨成超疏水粉末，一旦施加到表面上，使其成为超疏水的。多孔聚合物结构的形态可以通过聚合混合物的组成来有效地控制，而表面化学可以通过光接枝来调节。形态控制用于将多孔结构的小球尺寸从微米减小到纳米级，从而提供透明材料。讨论了表面化学性质和表面粗糙度对超疏水性的影响。
We present a facile and inexpensive approach to superhydrophobic polymer coatings. The method involves the in-situ polymerization of common monomers in the presence of a porogenic solvent to afford superhydrophobic surfaces with the desired combination of micro- and nano-scale roughness. The method is applicable to a variety of substrates and is not limited to small areas or flat surfaces. The polymerized material can be ground into a superhydrophobic powder, which, once applied to a surface, renders it superhydrophobic. The morphology of the porous polymer structure can be efficiently controlled by composition of the polymerization mixture, while surface chemistry can be adjusted by photografting. Morphology control is used to reduce the globule size of the porous architecture from micro down to nanoscale thereby affording a transparent material. The influence of both surface chemistry as well as the length scale of surface roughness on the superhydrophobicity is discussed.
