Study of calcite single crystals growth with different morphology regulated under biologic monolayer
Abstract：In this paper, the nucleantion and oriented growth of the calcium carbonate crystals induced by di- palmitoylphosphatidylcholine （DPPC） Langmuir monolayers as the template was investigated through a sery of techciques such as SEM and XRD. The results showed that calcium carbonate crystals with cube or petal-like crystal morphology could be obtained by changing the concentration of the calcium carbonate solution under the DPPC Langmuir monolayer. However, the crystal shape of these crystal induced under DPPC monolayer was calcite single crystals with orientated growth along （104） palne. All the results suggested that DPPC Langmuir monolayer could be used as a template to induce and regulate the oriented growth of the calcium carbonate with complex morphologies. Moreover, the regulation mechanism of monolayer to crystal growth and the mechanism of the influence of the calcium concentration on crystal morphology were also further discussed.
