我们提出了一种简单而经济的方法来生产潜在的开放式微流体聚合物器件，使用相分离方法在聚苯乙烯上制备仿生超疏水表面，通过将表面暴露于等离子体或UV，将图案化的二维通道印迹在超疏水基底上。通过改变臭氧的照射量，可以精确地控制通道的润湿性，使其在超疏水和超亲水状态之间变化时间发现超亲水路径在水平位置驱动液体流动的能力显着高于在光滑表面上图案化的亲水路径的情况（C）2010日本应用物理学会
We present a simple and economical method to produce a potential open microfluidic polymeric device Biomimetic superhydrophobic surfaces were prepared on polystyrene using a phase separation methodology Patterned two-dimensional channels were imprinted on the superhydrophobic substrates by exposing the surface to plasma or UV-ozone radiation The wettability of the channels could be precisely controlled between the superhydrophobic and superhydrophilic states by changing the exposure time The ability of superhydrophilic paths to drive liquid flows in a horizontal position was found to be significantly higher than for the case of hydrophilic paths patterned onto smooth surfaces (C) 2010 The Japan Society of Applied Physics
