摘要
研究了不同温度(298K,313K,333K,353K,和373K)下Ch Cl/Cr Cl3·6H2O离子液体微波波谱图,结果显示333K以下介电常数(εˊ)和介电损耗(ε〞)均随温度的增加而增加。这是由于不同离子赋存形态的极化现象影响了介电损耗。介电品质因数随着Cr Cl3·6H2O摩尔分数的增加而减小,这是由于电导率的增加而造成的。
The microwave spectrum of ChCI/CrC13·6H2O ionic liquid of the different molar concentration of CrC13·6H20 were measured at 298K, 313K, 333K, 353K, and 373K. The results indicated that dielectric constant （εˊ ） and the dielectric loss （εˊ ） increases monotonously with the increase of temperature when the temperature is below 333K due to that the orientation polarization strongly affects the dielectric loss. It is demonstrated that the dielectric properties are decreased with the decrease of molar fraction of CrC13·6H20, which can be described by the increasing of the electric conductivity.
