WebThe graphite nanosheets (GNS) are low-cost fillers, which are obtained through chemical and physical treatments of natural graphite. The GNS are formed by several graphite sheets of a few nanometer thick and from hundreds to thousands nanometer longs connected by van der Waals forces [ 11 ]. WebThe graphene oxide (GO) nanosheet, one of the carbon allotropes, is frequently exfoliated from the natural graphite powders via chemical-wet exfoliation methods. The as-prepared GO sheets are usually composed of a large amount of oxygen functionalities, such as carboxyl (C–OOH), carbonyl (C=O), and hydroxyl (C–OH) groups [ 33 ].

WebAlthough this method was first applied to exfoliate graphite to yield graphene nanosheets, it has since been used to produce a wide range of 2D materials including molybdenum disulfide, tungsten diselenide, boron nitride, nickel (II) hydroxide, germanium monosulfide, SnP 3, and black phosphorus.
