Advanced Nanostructured Hybrid Coatings for the Protection of Aircraft

摘要

Corrosion protection properties of sol-gel-clay- polyelectrolyte coatings are investigated in this project. The inspiration for this anticorrosion coatings are taken from the natural organic-inorganic composite mother-of-pearl (aka nacre). It reveals numerous unique mechanical properties including, strength, toughness, and wear resistance, which are attributed to the layered structure of the nacre materials (Figure 1). The goal of this project is to create a multifunctional nacre-like coating with excellent mechanical and corrosion resistant properties. The layer-by-layer (LBL) method is used as a primary method of structural design of the coatings and enables combining different functionalities in the multilayer structure. Sol-gel overcoat is used to enhance the barrier and corrosion protection properties of the entire coating.
