Method I: Prepare a solution of the superhydrobhobic material in some organic solvent of appropriate concentration then dip your mesh in the solution. You might to have optimize the concentration of the superhydrophobic solution.
Method 2: Melt your superhydrobic material (if it is possible i.e., if it does not decompose) then dip your mesh in the melt and allow it to cool.
You can also use other methods such as laser ablation etc.
