Abstract:
Organic/inorganic hybrids have been intensively investigated in the past two decades and exhibited promising performance. Typically, the capability to control the structure and morphology is the key to achieve desired properties. While the conventional organic/inorganic hybrids are promising in certain general purpose applications, it is highly desirable to develop new synthetic approaches to meet more demanding applications. In this work, biomimetic organic/inorganic hybrid nanocoatings with a nacre-like microstructure were prepared via a facile co-assembly process. Such nanocoatings contain a high concentration of well-aligned and crosslinked nanosheets. As a result, the nanocoatings exhibit exceptional mechanical, barrier, and flame retardant properties, but meanwhile they are highly transparent. Such nanocoatings can also be coated on specific substrates to generate various microstructures such as micro-cracks and wrinkles, leading to tunable optical properties.
