Chemical nanopatterns down to 50 nm in feature size have been fabricated via nanoimprint lithography and used to simultaneously control azimuthal and polar orientation of liquid crystals (LCs). The polar orientation depends on the ratio of the homeotropic/planar surface potential areas, while the LC azimuthally orients along the direction of the silane patterns.
通过纳米压印光刻技术制备出了特征尺寸低至50纳米的化学纳米图案，并将其用于同时控制液晶（LC）的方位角和极性取向。极性取向取决于垂直/平面表面势区域的比例，而液晶沿硅烷图案的方向进行方位取向。
