We have fabricated patterned fibers using a small-molecular-weight liquid crystal (LC) and reactive mesogens (RMs) under controlled electric fields in which defect arrays are generated depending on the electrode configuration. For this, the AC electric field with interdigitated electrodes is used to develop versatile defect structures of the LC phase. Hydrophobic LC network (LCN) fibers exhibiting porous morphologies have been made by removing the LC part after the polymerization of RM. The resulting LCN fibers show a surface tension reduction characteristic compared to the neat RM film and a sticky characteristic with the water droplet, suggesting a facile way to fabricate the hydrophobic surface that can be used in microdroplet transport.
我们使用小分子液晶（LC）和反应性介晶（RM）在受控电场中制造图案纤维，根据电极配置生成缺陷阵列。为此，使用具有交错电极的交流电场来开发 LC 相的多功能缺陷结构。通过聚合 RM 后去除 LC 部分，制备了具有多孔形态的疏水性 LC 网络（LCN）纤维。与纯 RM 膜相比，所得 LCN 纤维表现出表面张力降低的特性，并且与水滴具有粘性特性，表明可以制备用于微液滴传输的疏水性表面的简便方法。
