There are non-classical pathways of crystallization via colloidal intermediates and subsequent mesoscale transformation in many crystallization processes. With polymeric additives, self-organization can be stopped at an intermediary step -a mesocrystal- in which the primary crystal units can still be identified. The influence of polymers on crystal formation is attributed to their selective adsorption and/or enrichment onto specific crystal faces, similar to that seen with low molecular weight ionic compounds, which inhibits the growth of these faces. To understand the effects and relevant parameters for the formation of mesocrystals, the crystallization of charged molecules with oppositely charged polymeric additives was performed. |
