“…To solve the abovementioned problems, many researchers have made significant efforts to use graphene as an adjuvant in combination with other conventional flame retardants such as intumescent flame retardants and aluminium hydroxide [46][47][48][49][50][51], melamine polyphosphate [52], carbon black [53], layered double hydroxides (LDHs) [54], brominated polystyrene and antimony trioxide (Sb 2 O 3 ) [55], and aluminium hypophosphite [56]. As shown in Fig.…”

Graphene and its derivatives are potential flame retardant materials with good flame retardant performance; in particular, graphene as an adjuvant in combination with inorganic nanomaterials may be a promising candidate of flame retardant. This review describes the flame retardant mechanism, the development trend, and the classification of graphene-based flame retardants. It points out that graphene has attracted intensive interests in the fields of electronics, energy, and information, due to its excellent properties such as high thermal conductivity, good electron transport ability, and large specific surface area. In the meantime, graphene can change the pyrolysis as well as the thermal conductivity, heat absorption, viscosity and dripping of polymer during the combustion process. In other words, graphene can improve the thermal stability of polymer and delay its ignition, and it can also inhibit fire from spreading and reduce heat release rate.

“…The well-dispersed graphene can work as an anti-dripping agent and increase the melt viscosity of polymer composites [15,16,18]. Graphene has been employed as a synergist with conventional flame retardants and nanoparticles, such as intumescent flame retardant, magnesium hydroxide, and carbon black [19][20][21].…”

Graphene oxide (GO) is modified by melamine (MA) via the strong p-p interactions, hydrogen bonding, and electrostatic attraction. PP composites are prepared by melt compounding method, and GO/functionalized graphene oxide (FGO) is in situ thermally reduced during the processing. The results of scanning electron microscopy and transmission electron microscopy indicate that FGO nanosheets are homogeneously dispersed in polymer matrix with intercalation and exfoliation microstructure. The FGO/PP nanocomposite exhibits higher thermal stability and flame retardant property than those of the GO counterpart. During the thermal decomposition, the intercalated MA is condensed to graphitic carbon nitride (g-C 3 N 4 ) in the confined micro-zone created by GO nanosheets. This in situ formed g-C 3 N 4 provides a protective layer to graphene and enhances its barrier effect. The heat release rate and the escape of volatile degradation products are reduced in the FGO-based nanocomposites.

“…The addition of CNPs into polymer matrices has shown a marked improvement in the physicochemical properties of the nanocomposites; moreover, there is a tendency to add a mixture of two or more different carbon nanoparticles aiming to obtain a synergistic effect in the final properties of polymer nanocomposites [6,[15][16][17][18][19]. For example, when one-dimensional carbon nanostructures (CNTs or CNFs) are intercalated with GPs or graphene (2D), a 3D network is promoted, which allows a greater interaction and a better 2 Journal of Nanomaterials dispersion and spatial distribution of the CNPs in the polymer matrix [18,20].…”

Carbon nanofibers (CNFs), graphene platelets (GPs), and their mixtures were treated by plasma polymerization of propylene. The carbon nanoparticles (CNPs) were previously sonicated in order to deagglomerate and increase the surface area. Untreated and plasma treated CNPs were analyzed by dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and thermogravimetric analysis (TGA). DLS analysis showed a significant reduction of average particle size, due to the sonication pretreatment. Plasma polymerized propylene was deposited on the CNPs surface; the total amount of polymerized propylene was from 4.68 to 6.58 wt-%. Raman spectroscopy indicates an increase in the sp 3 hybridization of the treated samples, which suggest that the polymerized propylene is grafted onto the CNPs.
