Aluminum–nickel oxide and graphene oxide hybrid films are investigated in this study. The films produced via solution processing were doped with GO at three concentrations: 0, 5, and 15 wt%. The optical transmittances of the produced hybrid AlNiO films were examined for liquid crystal device applications, and their chemical properties were assessed via X-ray photoelectron spectroscopy. Atomic force microscopy and line profiling were used to examine the film surfaces. Polarized optical microscopy and pretilt angle analysis were used to confirm the uniform and homogeneous LC alignment on the hybrid AlNiO layer. The anisotropic oriented nano/microgroove structures on the surfaces of the films are believed to be due to the shear stress generated by the brush-coating process. LC cells assembled using the hybrid films showed stabler and faster switching performances with increasing GO doping. GO doping of the pure AlNiO film was also noted to increase the LC polar anchoring energy.

本研究研究了铝镍氧化物和石墨烯氧化物杂化薄膜。通过溶液处理生产的薄膜掺杂有三种浓度的 GO：0、5 和 15 wt%。对所生产的混合 AlNiO 薄膜的光学透射率进行了液晶器件应用的检查，并通过 X 射线光电子能谱评估了它们的化学性质。使用原子力显微镜和线分析来检查薄膜表面。使用偏光光学显微镜和预倾角分析来确认混合 AlNiO 层上的均匀一致的 LC 排列。薄膜表面上的各向异性取向的纳米/微槽结构被认为是由于刷涂过程产生的剪切应力造成的。随着GO掺杂的增加，使用混合薄膜组装的液晶电池表现出更稳定和更快的开关性能。纯 AlNiO 薄膜的 GO 掺杂也被发现可以增加 LC 极性锚定能。
