论文摘要
理解和工程液态液体界面处的软胶体颗粒（微凝胶）的自组装正在扩大它们在胶体光刻中的使用。在这里，我们提出了一条新的途径，以接近零的表面压力组装微凝胶的矩形晶格，该途径依赖于有吸引力的四极毛细管相互作用与水/油界面颗粒之间的空间排斥之间的平衡。这些自组装的矩形晶格是在广泛的颗粒中获得的，在沉积后，可以用作光刻掩模，以通过潮湿和干蚀刻过程获得垂直排列的纳米线的常规阵列。
Understanding and engineering the self-assembly of soft colloidal particles (microgels) at liquid-liquid interfaces is broadening their use in colloidal lithography. Here, we present a new route to assemble rectangular lattices of microgels at near zero surface pressure relying on the balance between attractive quadrupolar capillary interactions and steric repulsion among the particles at water/oil interfaces. These self-assembled rectangular lattices are obtained for a broad range of particles and, after deposition, can be used as lithography masks to obtain regular arrays of vertically aligned nanowires via wet and dry etching processes.
