Abstract应用长工作距显微镜对胶体粒子自组装过程中初形核阶段进行了原位观察实验研究,并结合三相接触线附近流场的数值模拟结果对绕流的影响进行了研究.研究表明流线在短链附近发生弯曲.当颗粒靠近短链附近时,水平流将颗粒推向短链的端部.绕流将抑制形核过程中局部的过快生长,从而保持生长前沿平直
Other AbstractAn in-situ observation of the initial nucleation of the colloidal crystal was performed by utilizing a long working distance microscope.The streamlines in the vicinity of the three-phase contact line are calculated by the fluid dynamics software Fluent.The trajectory of the particle indicates that the streamline is bent around short chains.When the particle goes close to a short chain,a horizontal flow pushes the particle to the end of the short chain(flowing-around,FA).The simulation indicates that the particles have the ability of self-adjusting when they are assembled into a colloidal crystal.The FA would inhibit too fast growth in a local area,which would lead to a straight growth front.This study provides an insight into the self-assembling dynamics and the nucleation process for colloidal crystal growth.
