摘　　要：用β-环糊精(简称β-CD)、对甲苯磺酸、磺基水杨酸、对氨基苯磺酸、对苯二甲酸、α-萘乙酸和2,6-吡啶二羧酸为原料,采用固相反应,合成了新型的电流变材料———以β-环糊精为主体、磺基水杨酸等有机酸为客体的包合物.研究了材料的组成结构与材料电流变性能的关系.结果表明:包合对甲苯磺酸和磺基水杨酸可以明显的提高主体β-环糊精的电流变性能,β-环糊精与磺基水杨酸的包合物有最高的电流变活性.A novel type of electrorheological（ER） materials,the inclusion compounds between β-cyclodextrin（β-CD） as the subject,and organic acids as the objects are synthesized using β-CD,p-toluenesulfonic acid,sulfosalicylic acid,p-aminobenzenesulfonic acid,terephthalic acid,a-naphthylacetic acid and 2,6-dipicolinic acid as original materials by a solid reaction.The relationships between ER performance of the materials and their composition structures are studied.The results show that p-toluenesulfonic acid or sulfosalicylic acid as the guest can enhance obviously the ER performance of β-CD as the subject.The inclusion compound between β-CD and sulfosalicylic acid has the highest ER activity.
