An ingenious device is presented to study the interactions between a charged droplet and particles under an applied electrostatic field on the microscale.During the experiments,particles laid flat on a concave sheet are attracted by a charged droplet,which is hung on a plain-orifice nozzle above the plane.Particles move from the sheet to the droplet as the result of Coulomb and electric field forces.Not all the particles are captured by the charged droplet; most of them adhere to the droplet surface while others bounce off.For particle clusters especially,their looser structures cause them to more easily disintegrate when impacting the droplet surface,which leads to secondary dispersion.An incidence-angle hypothesis is presented to explain the rebound of particles: If the incidence angle of the particle is <90°,the particle may bounce off the droplet.
