【摘要】：在永久磁場(chǎng)作用下,磁性座滴的變形以及與另一非磁性座滴的合并可以通過研究坐落在疏水表面的兩種座滴來實(shí)現(xiàn)。當(dāng)兩座滴互相接觸時(shí),兩座滴表面能的釋放導(dǎo)致合并過程瞬間發(fā)生。此后,合并后的座滴會(huì)隨著磁鐵繼續(xù)運(yùn)動(dòng),從而非磁性座滴的混合在移動(dòng)過程中出現(xiàn)并得到促進(jìn)。試驗(yàn)中清楚觀察到了座滴移動(dòng)并與熒光座滴混合的動(dòng)力學(xué)過程。非磁性座滴中放入了熒光粉,使得合并過程以及合并完成后座滴內(nèi)的濃度分布可以得到直接且便捷的觀察。
[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.
