Stabilization and Coagulation of Colloidal Suspensions during Crystallization

Due to special properties different from those of solutions and solids, the colloidal suspension is considered for the precursor of promising functional materials such as colloidal nanocrystals. However, a colloidal suspension could also cause a negative effect for phase transformation processes like crystallization. Hence, understanding the nucleation and interaction of particles is crucial and instructive to control the colloid suspension. In this study, the motion behavior of particles and its effect on colloidal stability were systematically studied and characterized at multiple stages and multiple scales through surface analysis of the nanocrystal, thermodynamic derivation, zeta potential measurements, and rheological studies. Through theoretical model calculations, the interaction and motion behaviors of particles were further discussed, and the destruction of the colloidal suspension was investigated and analyzed.
