近年来,许多研究者试图将液晶高分子和纳米材料二者通过物理掺杂或化学接枝的方法混合,构建有序的有机/无机杂合体,该类杂合体系除表现出各组分自身的性质外,更由于它们间的相互作用而展现出新的特性。目前,研究的主要方向是通过掺杂纳米材料来提高液晶材料性能。本文论述了CNT掺杂液晶复合材料的研究进展,按照液晶类型不同可以分为铁电液晶、向列型液晶、盘状液晶以及液晶高分子,考察了CNT在液晶分子中的排列,CNT对液晶的相转变温度的影响,以及对复合材料光电性能和导电性能的影响。
In recent years, many researchers have tried to mix both liquid crystal polymers and nanomaterials by physical doping or chemical grafting to form ordered organic / inorganic hybrids which, in addition to exhibiting their own components But also because of the interaction between them and show new characteristics. At present, the main research direction is to improve the properties of liquid crystal materials by doping the nanomaterials. In this paper, the research progress of CNT doping liquid crystal composite materials is reviewed. According to different types of liquid crystal, ferroelectric liquid crystal, nematic liquid crystal, discotic liquid crystal and liquid crystal polymer can be divided into three parts. Of the phase transition temperature, as well as the composite optical properties and electrical conductivity.
