采用分子自组装的方法制备了β-环糊精聚合物包结物颗粒用荧光分析和红外光谱表征了包结物的结构.发现客体1-(2吡啶偶氮)-2-萘酚中极性较小的萘环进入了环糊精内腔.用β-环糊精聚合物及其自组装包结物颗粒与二甲基硅油配制了两种电流变液.对其流变学性能的研究发现.包结物电流变液在直流电场5 kV/mm中的静态屈服应力可达6.2 kPa,比主体提高近3倍:介电测试的结果表明包结物的介电常数为5.35,电导率为2.97×10-9 S/m,均高于主体.其中电导率比主体提高了10倍多:抗沉降性能测试结果为:自组装包结物存放300 h,其沉降率为89%,而主体仅为76%.包结物电流变液性能的提高可能与主客体间存在的超分子作用、客体的属性等有关.
