摘　　要：以4,4’-二羟基-α,α’-二甲基苄连氮(DDBA)和羟基硅油合成了系列带有磺酸基团的液晶离聚物(LCI)。合成的LCI与聚苯胺原位聚合制备出系列复合材料。采用红外光谱表征了LCI和复合材料的结构;用差示扫描量热法表征了复合材料的液晶性能;交流阻抗法测量了复合材料的电导率;结果表明:掺杂后的最大电导率能达到9.0×10-5S/cm。Experiments synthesized a series of liquid crystalline ionomers （LCI）with sulfonic group using different proportion of 4,4＇-dihydroxy α, α＇-dimethyl benzyl nitrogen （DDBA） and hydroxy silicone. A series of LCI and polyaniline were prepared for different composite materials. Infrared spectroscopy was used to characterize the structure of LCI and composite materials;differential scanning calorimetry was used to characterize thermal information; and using AC impedance me^i~od measured the conductivity of compositc materials. The result showed that the biggest electrical conductivity was 9.0×10^-5 S/cm.
