Question

英语翻译
CaCO3 superstructures with complex forms and hierarchical surface textures were mineralized in the presence of peptide type block copolymer poly(ethylene glycol)-b-poly(L-glutamic acid) (PEG-b-pGlu) as a crystal growth modifier in dimethyl formamide (DMF) solution.Spindle-like CaCO3 crystals with a rather smooth surface and a size of 10 μm in length and a maximum diameter of 6 μm were mineralized at 242 °C.Unique ellipsoid-like CaCO3 particles with many similar thorns distributed on the particle surface formed when the mineralization temperature was kept at 142 °C.Complex column-like CaCO3 superstructures comprised of many tiny rods and irregular particles were observed at 42 °C.In addition,when the reagent concentration is varied,the morphology of CaCO3 changes from a mixture of spherical and ellipsoidal structures to a kind of complex ellipsoidal superstructure whose surface is attached by many hierarchical tubular structures,and then to a complex columnar structure,when the concentration of Ca2+ ions was varied from 40 to 20 mM and finally decreased to 10 mM,respectively.Correspondingly,phase transition occurred from a mixture of aragonite and calcite to pure calcite,and then to a mixture of vaterite and calcite when the mineralization temperature increased.Moreover,changing the polymer concentration resulted in phase transition from calcite to a mixture of aragonite and calcite,and then to a mixture of vaterite and calcite.An emergent self-organization process and its combination with an aggregated mechanism have been proposed for the formation of the complex ellipsoidal superstructures.The results imply that the specific biomimetic synthesis strategy in a nonaqueous solution can provide a useful pathway to produce inorganic or inorganic/organic hybrid materials with a unique morphology and specific textures.
