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中的静态屈眼应力可达 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 ２．９７×１０－９Ｓ／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．
Β-Cyclodextrin polymer inclusion particles were prepared by molecular self-assembly method. The structure of the inclusion complex was characterized by fluorescence analysis and infrared spectroscopy. It was found that the less polar naphthalene ring in the guest 1- (2-pyridylazo) -2-naphthol entered the cyclodextrin lumen. Dextrin polymer and its self-assembly enveloping particles and dimethicone prepared two kinds of ER fluids. The rheological properties of the inclusions show that the static refractive error of the inclusion fluid can reach 6.2 kPa at 5 kV / mm in the DC electric field, which is about 3 times higher than that of the bulk. The results of the dielectric test show. The dielectric constant of inclusions is 5.35, the conductivity is 2.97 × 10-9S / m, which is higher than that of the bulk, in which the electrical conductivity is more than 10 times higher than the bulk: the anti-settling property test results are: self-assembly When the inclusion was stored for 300 h, the sedimentation rate was 89%, while the main body was only 76%. The improvement of ER fluid properties of inclusion fluid may be related to the existence of supramolecular interactions between guest and guest and the properties of guest.
