Simulation and experiment on the viscosity of [C4mim][BF4]

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].
