Abstract
- In this work, a novel 3D graphene/Fe 3 O 4 (G-Fe 3 O 4) nanocomposite was prepared by a facile one-pot hydrothermal process used to be adulterated into the varnish as an anticorrosive and electromagnetic shielding paint. It is confirmed that the skeleton structure of graphene can effectively inhibit Fe 3 O 4 agglomeration by Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) technique, and the G-Fe 3 O 4 nanocomposites can be well dispersed in the varnish for a longtime without settling. The graphene/Fe 3 O 4 composite varnish shows excellent corrosion resistance both in city water and seawater, besides its corrosion resistance is also superior to that of ordinary anti-rust paint. Moreover, the electromagnetic shielding test confirms that the as-prepared composite varnish shows well electromagnetic shielding performance. This new type of composite varnish has a broad application prospect to be used as urban exterior wall and ships paint. [ABSTRACT FROM AUTHOR]
