我们报道了在静电场的驱动下，在水滴周围制造二氧化硅、煤或闪锌矿颗粒的复杂结构。在偏压的衬底上沉积一个颗粒床，一个接地的水滴靠近，使颗粒跳到水滴中。这些结构的形状和内部组成是由颗粒的润湿性和电学性质共同决定的，其他属性，如形状、大小和密度也被认为起到了作用。亲水性颗粒倾向于被液滴内化，而疏水性颗粒则倾向于在表面形成一层或一层壳。因此，这些结构的一个例子是具有亲水颗粒悬浮核心和由疏水颗粒组成的稳定外壳的“复杂液体大理石”。
We report the manufacture of complex structures of silica, coal or sphalerite particles around a water droplet, driven by an electrostatic field. A particle bed was deposited on an electrically biased substrate and an earthed water drop brought close, such that the particles jumped to the drop. These structures' shape and internal composition were determined by a combination of the particles' wettability and electrical properties, and other attributes such as shape, size and density were also thought to play a role. Hydrophilic particles tend to be internalised by the drop, while hydrophobic ones tend to form a layer or shell on the surface. Thus, one example of these structures was a ‘complex liquid marble’, with a hydrophilic particle suspension core and a stabilising shell of hydrophobic particles.
