摘      要：Ga-based liquid metal has drawn attention in the field of interface science due to its large ***, the spreading and shaping of liquid metal still remain a huge challenge to be solved owing to its large surface ***, an intriguing synergistic oxidation-driven liquid metal fractal phenomenon was discovered and the general mechanisms were interpreted, which provides a new strategy for manipulating liquid *** results demonstrate that the liquid metal placed on the graphite plate exhibited fractal characteristics with the addition of hydrogen ***, it is of significance that hydrogen peroxide and graphite plates synergistically oxidize liquid *** addition, we predicted that liquid metal fractals can also be achieved on other eligible substrates based on the proposed general mechanism, which was confirmed by relevant ***, the fractal dimensions of liquid metal fractal pattern were obtained and evaluated, distinguishing the synergistic oxidation-driven liquid metal fractals from the voltage-driven liquid metal ***, we initially gave the best concentration range in which dendritic fractals can occur in order to guide *** ability to achieve liquid metal fractals promises rich opportunities in freely driving the liquid metal for soft machines and manufacturing the shape-reconfigurable electronic circuits.
