【摘要】：在永久磁场作用下,磁性座滴的变形以及与另一非磁性座滴的合并可以通过研究坐落在疏水表面的两种座滴来实现。当两座滴互相接触时,两座滴表面能的释放导致合并过程瞬间发生。此后,合并后的座滴会随着磁铁继续运动,从而非磁性座滴的混合在移动过程中出现并得到促进。试验中清楚观察到了座滴移动并与荧光座滴混合的动力学过程。非磁性座滴中放入了荧光粉,使得合并过程以及合并完成后座滴内的浓度分布可以得到直接且便捷的观察。
[Abstract]:In a permanent magnetic field, the deformation of the magnetic pedestal droplet and its merging with another non-magnetic pedestal drop can be achieved by studying the two kinds of pedestal droplets located on the hydrophobic surface. When the two droplets contact each other, The release of the surface energy of the two drops causes the merging process to occur instantly. After that, the merged drops continue to move with the magnet. Thus, the mixing of nonmagnetic droplets appears and is promoted during the moving process. The kinetic process of the droplets moving and mixing with the fluorescent droplets is clearly observed in the experiment. The phosphors are placed in the nonmagnetic droplets. The merging process and the concentration distribution in the backseat can be observed directly and conveniently.
