説明:

Regulating droplet motion, with minimized energy input and adhesion loss, is promising for efficient liquid transportation. One efficient strategy is to design non-sticking droplets that exhibit regulated self-propelling. However, controlling the self-propelling trajectory while keeping a non-sticking property is challenging. Here, we developed a series of non-sticking solvent droplets that self-propelled on the water pool. These droplets are covered with omniphobic nanoparticles to become non-sticking, namely liquid marble. We found that the droplet self-propelling behavior, such as velocity and trajectory (i.e., polygonal, circular, spinning, and random), differed based on the liquid property (surface tension, solubility in water, volatility, etc.) owing to the branched underlying mechanism. The self-propelling driving force is not confined to the solute capillary force but extends to other forces, including the non-solute capillary, vapor-induced recoiling, and electrostatic force. The understanding of the self-propelling dynamics offered a basis for regulating the trajectories of self-propelling droplets of solvents from rectilinear to circular, random, stop-and-go motion, with a modulated transition time. Even liquid selective anti-wetting wettability at the perimeter of the water pool influenced the self-propelling behavior of the prepared liquid marbles. Thereafter, such liquid marbles were successfully explored in cargo transportation.
