摘要: We produced bunched aragonite nanorods through crystal growth controlled by an acidic polysaccharide, alginate, in a supersaturated solution. The highly ordered arrays of c-axis-elongated ∼100 nm diameter were grown on the (001) surface single-crystalline substrate with specific adsorption soluble polysaccharide. Freestanding films consisting obtained using insoluble anhydrous chitosan, as template for nucleation metastable phase. orientation rods was improved repetition growth. Parallel control polymorphism, orientation, and morphology molecular provides biomimetic hierarchical architectures calcium carbonate crystals.
