Abstract

A method for preparing superhydrophobic polytetrafluoroethylene materials by micro- and nanoimprinting is discussed. Surfaces with superhydrophobic properties were prepared by designing and imprinting micro- and nano-structures on polytetrafluoroethylene materials. The experiments on weather resistance and durability revealed that the microstructure of screens of different mesh sizes was processed onto the surface of PTFE material by micro-nano thermal imprinting to make it hydrophobic and oleophobic, and retained the original excellent properties of corrosion resistance and low surface attachment, etc. The material processed by the new method has a wide range of application prospects in various fields.
