摘　　要：为了研究离子液体的粘度特性,以1-丁基-3-甲基咪唑四氟硼酸盐([C4mim][BF4])离子液体为研究对象进行模拟计算与实验测试.基于分子动力学原理,编译了离子液体粘度的模拟计算程序,对[C4mim][BF4]离子液体完成了粘度模拟计算.搭建了粘度测试系统,进行离子液体的粘度测试.通过实验数据与模拟数据的对比,验证了模拟结果的准确性.另外,根据模拟粘度值的拟合曲线,分析了离子液体粘度的变化规律.同时,通过与水粘度的比对研究,阐述了[C4mim][BF4]离子液体的粘度特点.Regarding [C4mim][BF4] as the research object, simulation and experiment were carried out to study the viscosity property of ionic liquids. Based on the principle of molecular dynamics, a program on the viscosity of ionic liquids was compiled, and was used to simulate the viscosity of [C4mim][BF4]. A test system was established to test the viscosity of ionic liquids. The accuracy of the simulation results were analyzed by comparing the experimental data with the simulation data. The viscosity change law of the ionic liquids was illustrated aecording to the curve of viseosity on [C4mim][BF4]. The eharacteristie of viscosity on [C4mim][BF4] was introduced through comparing water with [C4mim][BF4].
