Ga-based liquid metal has drawn attention in the field of interface science due to its large deformability. However, the spreading and shaping of liquid metal still remain a huge challenge to be solved owing to its large surface tension. Here, 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 metal. Experimental results demonstrate that the liquid metal placed on the graphite plate exhibited fractal characteristics with the addition of hydrogen peroxide. Here, it is of significance that hydrogen peroxide and graphite plates synergistically oxidize liquid metal. In 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 experiments. Furthermore, 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 fractals. Besides, we initially gave the best concentration range in which dendritic fractals can occur in order to guide practice. The 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.

Ga基液态金属由于其较大的变形能力而受到界面科学领域的关注。然而，由于液态金属的表面张力大，液态金属的铺展和成型仍然是一个有待解决的巨大挑战。在这里，发现了一种有趣的协同氧化驱动的液态金属分形现象，并解释了一般机制，这为操纵液态金属提供了一种新策略。实验结果表明，放置在石墨板上的液态金属随着过氧化氢的加入而表现出分形特征。在这里，过氧化氢和石墨板协同氧化液态金属具有重要意义。此外，我们预测液态金属分形也可以根据所提出的一般机制在其他符合条件的基板上实现，相关实验证实了这一点。此外，获得并评估了液态金属分形图案的分形维数，将协同氧化驱动的液态金属分形与电压驱动的液态金属分形区分开来. 此外，我们最初给出了树枝状分形发生的最佳浓度范围，以指导实践。实现液态金属分形的能力有望为软机器自由驱动液态金属和制造形状可重构电子电路提供丰富的机会。
