Biomimetic crystallization of calcium carbonate spherules with controlled surface structures and sizes by double-hydrophilic block copolymers

摘要: Big CaCO3 spherules with controlled surface structures and sizes ranging from several hundreds of nanometers micrometers can be easily fabricated through a slow gas–liquid diffusion reaction at room temperature by using double-hydrophilic block copolymers (DHBCs) as crystal modifiers. The influence the DHBCs different functionalities such carboxyl, partially phosphated, phosphorylated groups on crystallization structure calcite formation was investigated. morphology evolution process early stage big spherical superstructures were followed. Such complex made rhombohedra are not produced conventional solution growth methods, furthermore show high potential for chromatographic purposes due to their exposition multiple faces huge particle suitable column packings.
