Abstract:

Ionic liquids are mainly applied in the field of chemistry and rarely applied as physical material. In this paper, ionic liquids are used as a new type of fluid material for microfluidic. We propose a novel method for driving an ionic liquid based on the principle of magnetic hydrodynamics. In order to visually observe and study the flow phenomenon of ionic liquids, we designed two experiments: the driving force measurement and the ionic liquid flow velocity measurement. Experimental results show that the flow rates are 7.8 μl/s at applied directcurrent potentials of 8V in a 0.4T magnetic field. The experimental results are compared with theoretical results to show the motion law of ionic liquids in driven magnetic field. Our research promotes the application of ionic liquids in microfluidics and optoelectronics.
