Abstract

This paper reports an electrochemical measurement system with a high-speed camera for observation of molecular transport phenomena at a water-oil (W/O) interface during microfluidic droplet formation. For demonstration of the system, currents corresponding to the transport of electrolyte ions to form the electrical double layer at the liquid interface were measured. Additionally, the high-speed camera observation revealed charge-effect on droplet stability during and/or just after the formation. This measurement system is expected to facilitate a full understanding of the droplet formation process.
