Microstructure and elemental characterization indicate that the finish of the coating with ‎the LBL film resulted in a closely multilayered coating with a smoother surface. The ‎principles of assembly are discussed together with the proprieties of nanoparticles and layer ‎by layer polymeric assembly essential in building hybrid coatings. They represent the key ‎components to enhance mechanical properties, enable activation by laser light or ‎ultrasound, construct anisotropic and multi-compartmental structures and facilitate the ‎development of novel sensors and movable particles. Here, we discuss an increasingly ‎important role of inorganic nanoparticles in the layer-by-layer assembly-effectively leading ‎to the construction of the so-called hybrid coatings.‎

The microstructure and elemental characterization indicated that the finish of the coating ‎with the LBL- film resulted in a closely connected multilayered coating with a smoother ‎surface. The anticorrosion performance was systematically evaluated in the simulated ‎corrosive medium and neutral salt spray environment. The integrated coating with the LBL-‎film, presents an excellent anticorrosion ability with system impedance over 10-6 micro-‎ohms/cm2 and a self-corrosion current density two orders of magnitude lower than that of ‎other coatings. After the acceleration test in a salt spray environment, the multilayered ‎coatings could still show a good protective performance with almost no cracks and no ‎penetration of chloride ions. It is believed that the as constructed multilayered coating with ‎high corrosive properties and a fine surface state will have promising applications in the field ‎of anticorrosion engineering.‎

The principles of assembly are discussed together with the properties of nanoparticles and ‎layer-by-layer polymeric assembly essential in building hybrid coatings. Applications and ‎emerging trends in development of such novel materials are also identified.‎
