“…The third category of flame retardant graphenenanocomposite flame retardants refers to conventional-organic flame retardant molecules graphenenanocomposite flame retardants. They include conventional-organic flame retardants such as phosphorus-containing organic flame retardants [40,[85][86][87], phosphorus-and nitrogen-containing organic flame retardants [88][89][90][91][92][93], and phosphorus-and siliconcontaining-organic flame retardants [94,95]. These organic flame retardants can functionalize graphene by inserting covalently bonded molecules between the layers of graphene (intercalation).…”

“…This increases the melt viscosity, restrains the molten drops and prevents the fire from spreading. The final decomposition products, silicate and silicon dioxide, are absorbed on the surface of the char and reinforce the thermal stability of the char layer, so as a result, the thermal stability and flame retardant properties of the composite are enhanced [67,68,94,100,101]. As expected, the combination of P-containing, N-containing, Si-containing and P-Ncontaining or Si-P-containing molecules with graphene may result in a synergic action in the condensed and gas phases, thereby improving the thermal stability and fire retardancy of composites (see Table 2).…”

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.

“…As displayed in Fig. 5b, the C 1s band spectrum of FGO was appeared at higher binding energies due to the covalent interaction between HDBTMSPU and GO [44]. Additionally, the peak area of C 1s band in FGO is higher than GO as a result of partial reduction of GO upon the functionalization process.…”

Three well-tuned procedures were used for thermal improvement of epoxy resin (E). Accordingly, graphene xerogel (GX) was used as nanofiller in the matrix of E. Additionally, (3-isocyanatopropyl)triethoxysilanemodified E (IE) or tetraethyl orthosilicate (TEOS) oligomer-modified E (TE) was incorporated into a hybrid structure of graphene-containing silica/siloxane network. For this purpose, a bifunctional silane coupling agent of 1,1 0 -(hexane-1,6-diyl)bis(3-(3-(trimethoxysilyl)propyl)urea) (HDBTMSPU) was synthesized. GX was obtained by incorporation of HDBTMSPU-modified graphene oxide (FGO) into xerogel structure using HDBTMSPU and TEOS. Modified resins, FGO, HDBTMSPU, and TEOS were also used in preparation of hybrid products. Thermal stability and char residue of the composites were compared. GO modification was approved by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, Raman, X-ray diffraction, and thermogravimetric analysis results. Hybrid composite of IE, FGO, and silica/siloxane network shows higher thermal properties. Char residue is increased by 16.93 % by loading of only 1 wt% of FGO in this hybrid product.

“…The C 1s band spectra of GO and FGO are shown at higher resolutions (Figure 5b). C 1s band spectrum of SFGO appears at higher binding energies compared with GO, which can be related to covalent grafting of HDBTMSPU to GO [47]. In addition, the peak area of C 1s band is higher in SFGO compared with GO due to reduction of GO upon the functionalization process.…”
