Wettability and permeation of ethanol/water mixture on porous mesh surface

In this paper, we fabricated a series of different chemical composition and roughness copper (Cu) meshes by using a one-step self-assembly method with different mixed thiols. The wetting behavior and the permeation behavior of ethanol/water mixed solution on different meshes were studied systematically. The manipulation of the wettability and permeation of these surfaces by controlling the concentration of the ethanol/water solution and the mole fraction of HS(CH 2 ) 2 OH in the modifier solution can be achieved. This work can not only help us to understand wettability of a mixture liquid on a surface, but also give us inspiration to design and fabricate new types of material for mixed liquid sensors. A serial of copper meshes with different chemical composition and roughness was prepared by modifying different mixed thiols, which showed different wetting behavior and permeation behavior for different ethanol/water mixed solution.
