中文摘要：

利用无毒、易得的β-环糊精（β-CD）作为主体,对甲基苯磺酸（PTA）作为客体,碳纤维作为掺杂材料,用研磨法,制得包合物（β-CD-PPTA）和碳纤维掺杂包合物（β-CD-PTA-C）电流变（ER）材料.FT-IR及XRD分析证实了包合物的形成.不同材料的电流变性质表明,包合PTA改善了β-CD材料的电流变性能,在包合物中掺杂碳纤维可以更有效地提高材料的电流变活性.另外,β-CD-PTA-C材料在硅油中的悬浮液具有良好的抗沉淀稳定性.

英文摘要：

The β-cyclodextrin inclusion compound and the inclusion compound doped with carbon fibre, were synthesized by a very simple grinding method. The nontoxic and facile β-cyclodextrin （β-CD） was selected as the substrate of the material, p-toluenesulfonic acid （PTA） and carbon fibre also were chosen as starting materials. The formation of the inclusion compound composed of the host （β-CD） and the guest （PTA） was determined by IR and XRD analysis. The investigations on the electrorheologieal （ER） properties of the particle materials have shown that PTA as the guest can improve the ER performance of β-CD （host） due to forming the inclusion compound, and the ER activity of the inclusion compound doped with carbon fibre is much higher than that of the inclusion compound. In addition, the suspension of the material doped with carbon fibre has higher anti-sedimentation stability than those of β-CD and its inclusion compound.
