We describe a method based on plasma polymerization for the modification and control of the surface properties of poly(dimethylsiloxane) (PDMS) surfaces. By depositing plasma polymerized acrylic acid coatings on PDMS, we succeeded to fabricate stable (several days) hydrophilic and patterned hydrophobic/hydrophilic surfaces. We used this approach to generate direct and (for the first time in this material) double emulsions in PDMS microchannels.
我们描述了一种基于等离子体聚合的方法，用于修饰和控制聚二甲基硅氧烷（PDMS）表面的性质。通过在PDMS上沉积等离子体聚合的丙烯酸涂层，我们成功制备了稳定的（持续数天）亲水性表面以及图案化的疏水/亲水表面。我们采用这种方法在PDMS微通道中产生了直接乳液以及（在这种材料中首次实现）双重乳液。
