It is a simple biomimetic technology that achieves surface wettability conversion by regulating the surface micro-nano structure, which can realize the conversion of the surface from high adhesion to low adhesion. The differences in surface microstructure primarily determine the two different wetting properties exhibited by rose petals and lotus leaves. This article studies the use of PS microspheres to construct bionic micro-nano structures on PDMS surfaces to achieve water adhesion regulation of superhydrophobic surfaces.
