在这封信中，我们报道了一种利用纳米结构印迹全氟聚合物和纳米结构二氧化硅的组合来制备超疏水/超亲水图案的技术。在我们之前的研究中，我们使用了疏水和超亲水材料的组合。然而，仅使用疏水/亲水模式很难将生物液体等低表面张力液体分离成液滴。在这项研究中，通过在损伤减少的全氟聚合物上进行纳米结构印迹，疏水性区域的接触角从109.3度增加到155.6度。开发的超疏水/超亲水模式允许即使是那些含有胎儿牛血清的培养液也可以分裂成所需形状的液滴。(C)2011年美国物理研究所。[DOI：10.1063/1.3570627]
In this letter, we report a technology for fabricating superhydrophobic/superhydrophilic patterns using a combination of a nanostructure-imprinted perfluoropolymer and nanostructured silicon oxide. In our previous study, we used a combination of hydrophobic and superhydrophilic materials. However, it was difficult to split low-surface-tension liquids such as biological liquids into droplets solely using hydrophobic/hydrophilic patterns. In this study, the contact angle of the hydrophobic region was enhanced from 109.3 degrees to 155.6 degrees by performing nanostructure imprinting on a damage-reduced perfluoropolymer. The developed superhydrophobic/superhydrophilic patterns allowed the splitting of even those media that contained fetal bovine serum into droplets of a desired shape.
