基于牛血清白蛋白LB膜模板诱导花瓣状碳酸锂结晶生长

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Li2CO3微晶.经SEM、XRD等表征 Li2CO3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Li2CO3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 sur-face topography of the obtained lithium carbonate crystallites were characterized by scanning electron microsco-py (SEM)and X-ray diffraction (XRD),and the formation mechanism was discussed.The results of character-ization indicate that BSA LB film can be used as a template to induce and regulate the lithium carbonate crystal-lites to crystallize with a special growth orientation and complex morphologies.
