摘　　要：结合仿生合成的方法,采用牛血清白蛋白为模板利用LB技术诱导制备了具有取向性生长晶型和对称花瓣状形貌的Li_2CO_3微晶。经SEM、XRD等表征Li_2CO_3微晶的表面形貌、结晶性能,并对其形成机理进行了初步探讨。实验证明BSA LB模板对Li_2CO_3微晶的形貌和生长取向性有很好的调控作用。Lithium carbonate crystallites with the orientation of the crystal type and symmetry of petal shaped morphology were fabricated below a BSA monolayer by using biomimetic method.The microstructure and surface topography of the obtained lithium carbonate crystallites were characterized by scanning electron microscopy(SEM)and X-ray diffraction(XRD),and the formation mechanism was discussed.The results of characterization indicate that BSA LB film can be used as a template to induce and regulate the lithium carbonate crystallites to crystallize with a special growth orientation and complex morphologies.
