Preparation and structure evolution of bowknot-like calcium carbonate particles in the presence of poly(sodium 4-styrene sulfate)

[Display omitted] ► Bowknot-like CaCO3 particles are fabricated. ► The bowknot particle is mainly composed by ACC. ► A stepwise growth mechanism is proposed. ► Morphology evolution depends on PSS and Ca2+ ions. Calcium carbonate particles with a novel bowknot-like superstructure were fabricated in t...
