Description
Summary:The surfaces of plants represent multifunctional interfaces between the organisms and the environment. In this paper, biomimetic taro leaf-like structures with superparamagnetic and superhydrophobic performances were exactly copied on the wood surface through the soft lithography to improve the wood properties. Fe 3 O 4 nanoparticles were mixed into poly(dimethylsiloxane) PDMS suspensions to obtain Fe 3 O 4 /PDMS suspensions that commonly endow coats magnetic and microwave absorption properties, which were then cast onto the wood surface and packaged by PDMS stamps replicated from fresh taro leaves. Fe 3 O 4 /PDMS films, which coexisted superhydrophobic surface and superparamagnetic property, were created on the wood surface after the being dried and stamps were peeled off. The as-prepared wood surface exhibited unique taro leaf-like micro- and nanostructures, microwave absorption, superparamagnetism performances with maximum saturation magnetization ( M s ) of 22.9 emu g −1 and superior static superhydrophobicity with a water contact angle of 152° ± 2°. This research may provide a feasible pathway for constructing naturally biomorphic structures on the wood surface with tailored functions.
