摘要

为了弥补传统液晶取向方式存在的不足，研发出低成本、制作简单、取向效果更优异的取向技术，本文使用简单的实验方法将纳米ZnO自组装到氧化铟锡玻璃基板上，并通过改变ZnO的煅烧温度，调控其纳米结构；继而结合摩擦方法，实现对液晶分子预倾角的调控。实验结果表明，ZnO的煅烧温度越高，液晶分子的预倾角越接近0°。反之，煅烧温度越低，液晶预倾角越接近90°。本文通过调节自组装的ZnO纳米结构，实现了对液晶分子预倾角0°~90°范围内的调控。

Abstract

In order to make up for the shortcomings of the traditional liquid crystal orientation

a low-cost

simple and better orientation technology was developed. In this study

a simple experimental method was used to self-assemble ZnO nanoparticles onto indium tin oxide (ITO) glass substrate

and the nanostructure of ZnO was regulated by changing the calcination temperature. Then combined with the friction method

the preinclination of liquid crystal molecules can be adjusted. The experimental results show that the higher the calcination temperature of ZnO is

the more the preinclination of the liquid crystal molecules is close to 0°. On the contrary

the lower the calcination temperature is

the closer the liquid crystal preinclination angle is to 90°. In this study

by adjusting the self-assembled ZnO nanostructure

the preinclination of liquid crystal molecules in the range of 0°~90° was controlled.
