A Millifluidic Approach for Continuous Generation of Liquid Marbles
We introduce a millifluidic approach to continuously generate and collect macroscopic liquid-in-gas droplets by adapting an assembly automation machine called vibration bowl feeder. The approach demonstrates the possibility to continuously generate liquid marbles, which are liquid droplets coated with a layer of hydrophobic particles. The maximum fabrication rate is over 200 marbles per minute. The effects of different operating parameters such as vibration amplitude, hydrophobic powders, and viscosity of liquid on the properties of the resultant liquid marbles are investigated. The technique is general for all macroscopic liquid-in-gas droplet generation and represents a novel approach for efficient liquid dispensing and subsequent storage.
