High Stability Performance of Superhydrophobic Modified Fluorinated Graphene Films on Copper Alloy Substrates

الملخص EN

A stable self-cleaning superhydrophobic modified fluorinated graphene surface with micro/nanostructure was successfully fabricated on copper substrates via drop coating process.

Irregularly stacked island-like multilayered fluorinated graphene nanoflakes comprised the microstructure.

The fabricated films exhibited outstanding superhydrophobic property with a water contact angle 167° and water sliding angle lower than 4°.

The developed superhydrophobic surface showed excellent corrosion resistance with insignificant decrease of water contact angle 166° in 3.5 wt.% NaCl solution.

This stable highly hydrophobic performance of the fluorinated graphene films could be useful in self-cleaning, antifogging, corrosion resistive coatings and microfluidic devices.
