Novel non-wetted/wetted floatable polyethylene/Cu and porous-Ni/Cu (P-Ni/Cu) coatings have been designed and fabricated for anti-combination of gallium-based liquid metal alloy (LM) marbles in solutions. Both coated LM pairs show strong anti-combination resistances even under a large extrusion ratio. Additionally, both coatings also show strong bonding forces with LMs and are floatable on the surfaces of LMs. Driven by electric or magnetic fields, floatable polyethylene/Cu or P-Ni/Cu coatings on LM surfaces are guided by these external fields, and then restore the original arrangement by the surface tension of the LMs and buoyancy of the coatings themselves after removing external fields, by which these coated LM marble or LM marble pair exhibit the revisable conductivity transitions and magnetic driven motion applications. This work should present a new way for the clustering and functional application of LMs in solutions.
新型非湿润/湿润可漂浮聚乙烯/Cu和多孔Ni/Cu（P-Ni/Cu）涂层已被设计并制备出来，用于防止镓基液态金属合金（LM）弹珠在溶液中结合。即使在较大的挤压比下，两种涂覆的LM对都表现出很强的抗结合能力。此外，两种涂层与LM之间也都表现出很强的结合力，并且可漂浮在LM表面。在电场或磁场驱动下，LM表面的可漂浮聚乙烯/Cu或P-Ni/Cu涂层会被这些外部场引导，然后在去除外部场后，通过LM的表面张力和涂层自身的浮力恢复到原始排列，借此，这些涂覆的LM弹珠或LM弹珠对展现出可修正的导电性转变和磁驱动运动应用。这项工作应为LM在溶液中的聚集和功能应用提供一种新方法。
