Biomimetic macroscopic mesocrystalline films produced by oriented assembly of nanorods under magnetic field

摘要

Millimeter-scale mesocrystals and cross-lamellae mimicking the nanostructure of seashells were produced on a substrate through the three-dimensionally oriented assembly of c-axis-elongated calcite nanorods approximate to 50 nm wide and approximate to 500-1000 nm long by combining arrangement with evaporation-driven capillary force and alignment under an intense magnetic field.
