Title: 

Preparation, characterization and application studies of advanced anticorrosion coating materials

Abstract: 

In this lecture, we explore the preparation, characterization of three distinctive advanced anticorrosive coatings (including nanocomposite materials, electroactive materials, and biomimetic materials).  In the nanocomposite coatings, we present the preparation and characterization of a series of composites containing different nano-fillers (such as metal oxides, clays, and graphenes).  In the electroactive coatings, a series of aniline oligomer-based polymers (such as electroactive polyimide, polyamide, polyurethane, epoxy resin) were synthesized and characterized.   In the biomimetic coatings, we present the preparation and characterization of a series of polymeric coatings with the surface structure of natural leaf by nano-casting technique.  The anticorrosion performance of all three distinctive advanced coatings were performed by a series of electrochemical measurements (such as Tafel, Nyquist, and Bode plots) in saline conditions.
