摘要采用聚合诱导相分离法制备了聚合物分散液晶（PDLC）薄膜。本文通过化学改性提高了多壁碳纳米管（MWCNT）在液晶中的分散性，并研究了它们对PDLC薄膜形貌、电光性能和电导率的影响。结果表明，随着掺杂MWCNT或化学修饰MWCNT浓度的增加，PDLC膜的阈值电压和饱和电压降低，这是因为碳纳米管可以通过降低介质的电阻率和增加电池的电容来增强电场。可以明显地看出，掺杂化学修饰的MWCNT的PDLC膜的对比度高于MWCNT的对比度。图形抽象
ABSTRACT Polymer dispersed liquid crystal (PDLC) films are fabricated by well-known polymerization-induced phase separation method. In this paper, the dispersion of multi-walled carbon nanotubes (MWCNT) in liquid crystals has been enhanced by chemical modification and we have investigated their effects on the morphology, electro-optical properties and conductivity of the PDLC films. Results indicated that the threshold voltage and the saturation voltage of PDLC films decreased with the increase of the doping concentration of MWCNT or chemically modified MWCNT, because carbon nanotubes can enhance the electric field by reducing the resistivity of the medium and increasing the capacitance of the cells. It can be viewed obviously that the contrast ratio of the PDLC films doped with the chemically modified MWCNT is higher than that of the MWCNT. GRAPHICAL ABSTRACT
