我们展示了一种简单而有前景的制备大面积天然微结构铁翼的方法，该方法结合了生物模板技术和仿生技术，以自然结构为模板。复制品坚固耐用，疏水性强，并具有优异的磁性。精确地保留了翼鳞的微观结构。然后将这些复制品用作邮票，将其微结构转录到聚二甲基硅氧烷(PDMS)表面，然后用磁铁轻松地将邮票从PDMS上分离出来。在这种方法中，由于样品不是通过机械手段从PDMS弹性体中分离出来的，因此不会破坏PDMS的微观结构，通过调整印迹参数可以显著提高防伪水平。
We demonstrate a simple and promising method for the preparation of large-area natural microstructured Fe-wings which combines biotemplating and biomimetic techniques using natural structures as templates. The replicas were robust and hydrophobic, and also possessed excellent magnetic properties. The micro-structures of the wing scales were accurately retained. Then these replicas were used as stamps to transcribe their micro-structures to the surface of polydimethylsiloxane (PDMS), and the stamps were subsequently separated from the PDMS with ease by a magnet. In this method, as the samples are not detached from the PDMS elastomer by mechanical means, the microstructure of PDMS is not destroyed, and levels of anti-counterfeiting can be improved distinctly by adjusting the imprinting parameters.
