摘　　要：通过将不同尺寸的多壁碳纳米管(MWNTs)掺杂到聚合物稳定蓝相(PSBP)液晶中研究了体系的蓝相温度稳定性和电场响应性能。小尺寸MWNTs的加入使PSBP电诱导反射波谱宽化的阈值电压显著降低。MWNTs掺杂PSBP液晶光子晶体的电响应阈值场强降低至0.1 V/μm,在1.3 V/μm电场下反射光谱谱带宽度可从20 nm拓宽至310 nm。该材料在反射型显示、可调滤光片等领域具有潜在应用价值。The thermal stability and electrically responsive ability of composite material systems consist of polymer-stabilized blue phase（PSBP） and multi-wall carbon nanotubes（MWNTs） in different size were studied. The threshold voltages of electric field-induced broadening of reflection spectra can be greatly decreased by doping MWNTs,and it is found that the effect is closely related to the size of MWNTs. The threshold electric field strength is successfully decreased to about 0. 1 V/μm in the MWNTs doped PSBP liquid crystalline photonic crystal,and the bandwidth is broadened from 20 nm to 310 nm under electric field with 1. 3 V/μm. The materials are promising to be applied in areas of reflective-mode displays or tunable optical filters.
