Key Points

The study aims to demonstrate a method for rapidly switching between different surface appearances in gallium-based liquid metal.
Conducting anodic oxidation in an acidic solution.
Creating an oxide film to modify surface appearance.
Switching the display between a shiny silver and matte black.
Successfully switched the surface from silver to matte black and back.
Demonstrated rapid and reversible changes in appearance.
Proved that the method can be controlled through voltage application.

Implication

Localized anodic oxidation facilitates surface switching in a gallium liquid metal display, highlighting versatility.
