| 摘 要： | 用β-环糊精(β-CD),磺基水杨酸(H3A)和硝酸钇[Y(NO3)3]为原料,采用固相反应,合成了新型的分子基电流变材料——以β-CD为主体、H3A为客体的包合物以及相应的配合物. 通过材料的元素分析、红外光谱和X-ray粉末衍射分析确定了材料的组成. 研究了材料的组成和介电性质与材料电流变性能的关系. 结果表明,包合物和配合物的形成都可以明显地提高主体β-CD的电流变性能,与配合物比较,β-CD与H3A的包合物有更高的电流变活性. 材料的组成是影响材料电流变性能的重要因素.

| Abstract: | A novel type of molecule-based electrorheological (ER) material was synthesized using β-cyclodextrin (β-CD), sulfo-salicylic acid and Y(NO3)3 as original materials by a solid reaction, which includes the inclusion compound of β-CD (host) and sulfo-salicylic acid (guest) and the corresponding coordination compound. The compositions of the material were confirmed by the measures of elemental analyses, IR spectra and XRD analyses of materials. The relationships between ER performance with the composition and dielectric property of the materials were studied. Results show that the formation of the inclusion compound and coordination compound could enhance markedly ER performance of the novel material with β-CD as the host. The inclusion compound has higher ER activity than that of the coordination compound. The composition of a material is an important factor in influencing ER property of the material. |
