Nanomaterials in corrosion prevention

Thin films Nanograined coatings Nanocomposite coatings Smart coatings 

A few novel reports are available on nanoparticles/nanostmcture carriers (of organic corrosion inhibitors) in smart coatings. There is a new generation of active corrosion protection coatings corttposed of hybrid sol-gel films doped with halloysite nanotubes able to release the entrapped corrosion inhibitors in a controllable way (Shchukin et al., 2008). A sihca-zirconia-based hybrid film was 

More possible active sites (grain boundaries) 

Faster diffusion of alloying elements More effective surfeice passivation Higher electrical resistance Improved wear resistance 

Improved wear resistance Improved barrier properties Hydrophobhicity Improved active protection Improved UV protection etc.
