Abstract
Liquid marbles are droplets stabilized by hydrophobic particles.[1] Improved understandings of liquid marble coalescence are essential for their applications as micro-reactors in digital microfluidics.[2] When coalescence initiates, the fusion into a spherical droplet can be arrested by the particle barriers and end up in an intermediate shape. This work suggests that the extent of coalescence to be arrested is highly related to the size of particles. Jammed particles balance the Laplace stress and halt the relaxation of the arrested structure. Different dynamics of electro-coalescence of liquid marbles are visualized. Precise mapping of the coalescence can facilitate the fabrication of non-spherical supra-colloidal structures. © 2020 CBMS-0001
