Abstract

We have demonstrated that the liquid/solid interfacial structure of liquid marbles is determined by the surface-interface interaction between the encapsulating particles and liquid droplet. X-ray computerized tomography (X-ray CT) confirmed that the decrease of the solid-over-liquid spreading coefficient (SS/L) allowed the particles to be submerged in the liquid. Moreover, the difference in interfacial structure had a strong effect on the dynamic mechanical stability of liquid marbles. Two liquid marbles only merged upon contact when at least one liquid marble had a small SS/L value. X-ray CT observations also revealed that the liquid at the solid/liquid interface did not interdiffuse easily.
