Synthesis and characterization of corrosion resistance and superhydrophobic fluorine-based coating via sol-gel process

Superhydrophobic and anticorrosion hybrid coating was synthesized via sol-gel process. For this purpose, coating was synthesized based on sol-gel precursors utilizing TEOS, GPTMS and TBT and fluorine monomer incorporated in obtained coatings. All prepared solutions were coated on iron plates by 120 μm by film applicator and then cured in room temperature. The coatings were characterized using the techniques of AFM, EDS, and FTIR spectra. The corrosion resistance properties of the prepared superhydrophobic surfaces were checked based on polarization curves.  Physical properties of coatings were measured by taber test and pencil hardness test for scratch resistance. Hydrophobicity was measured as static water contact angle test. The corrosion resistance, taber abrasion resistance and hydrophobicity increased significantly by increasing within the content of the fluorine chains.   Superhydrophobic and anticorrosion hybrid coating was synthesized via sol-gel process.
