SUPERHYDROPHOBIC PVC BASED COATING
Superhydrophobic surfaces are favorable for coating applications to protect various substrates from aggressive environments. Combination of microstructured surface roughness and low surface energy build up the superhydrophobic properties. Currently produced superhydrophobic materials are not industrially attractive for large scale production as they requires multistep fabrication process, complicated surface treatments and the use of expensive materials in the formulation.
Most of the fabricated superhydrophobic surfaces appeared to have low mechanical durability as they can be easily damaged by routine use, resulting in a decline of their superhydrophobicity. The micro- and nano-particles filling is a promising method that would enhance their mechanical stability and durability. The introduction of those structures through the whole thickness of the material offers excellent wear and corrosion resistant that retain their superhydrophobicity even after repeated mechanical and chemical action.
