Description
Summary:Inspired from butterfly wings that exhibit unique dewetting properties and brilliant structural color synchronously, we reported here the preparation of biomimetic few‐layer graphene films through a template‐directed chemical vapor deposition method using laser‐structured Cu foil as substrates. Hierarchical micronanostructures, including microscale stripes derived from the laser scanning and nanoscale laser‐induced periodic surface structures (LIPSS), formed on Cu foil after a simple femtosecond laser treatment. By tuning the laser power, the surface roughness of the resultant Cu foils can be well controlled. Using the laser structures Cu foil as templates, biomimetic few‐layer graphene films with both iridescence and superhydrophobicity have been successfully prepared. The present work may open up a new way to design and prepare structured graphene film in a biomimetic manner, and we deem that the bioinspired few‐layer graphene films may find broad applications in the near future. Inspired from butterfly wings, biomimetic few‐layer graphene films have been prepared through a template‐directed chemical vapor deposition method using laser‐structured Cu foil as substrates. The resultant few‐layer graphene films demonstrate both iridescence and superhydrophobicity. The present work may open up a new way to design and prepare structured graphene film in a biomimetic manner.
