Preparation method for wear-resistant super-hydrophobic coating on surface of sampling needle

The present invention relates to the field of preparation of superhydrophobic coatings on the surfaces of metal materials, in particular to a method suitable for preparing a rub-resistant superhydrophobic coating on the surface of a sampling needle. According to the present invention, firstly, a micron-sized rough structure is constructed on the surface of a sampling needle by adopting a cathode-coated three-electrode dynamic coaxial etching method; then a polytetrafluoroethylene (PTFE) film is prepared on the substrate surface of the sampling needle with the micron rough structure by using a dip-coating film forming method; after heat treatment, the surface of the sampling needle is in a rolling superhydrophobic state. The superhydrophobic coating prepared on the sampling needle by the method has good rub resistance, not only can reduce the liquid adhesion phenomenon on the surface, reduce the contamination carrying rate of the surface and improve the detection precision of the sampling needle, but also can prolong the service life of the superhydrophobic sampling needle, and has good industrial application prospects.
