Polymer materials are ubiquitous in daily life. While polymers are often convenient and helpful, their properties often obscure the fire hazards they may pose. Therefore, it is of great significance in terms of safety to study the flame retardant properties of polymers while still maintaining their optimal performance. Current literature shows that although traditional flame retardants can satisfy the requirements of polymer flame retardancy, due to increases in product requirements in industry, including requirements for durability, mechanical properties, and environmental friendliness, it is imperative to develop a new generation of flame retardants. In recent years, the preparation of modified two-dimensional nanomaterials as flame retardants has attracted wide attention in the field. Due to their unique layered structures, two-dimensional nanomaterials can generally improve the mechanical properties of polymers via uniform dispersion, and they can form effective physical barriers in a matrix to improve the thermal stability of polymers. For polymer applications in specialized fields, different two-dimensional nanomaterials have potential conductivity, high thermal conductivity, catalytic activity, and antiultraviolet abilities, which can meet the flame retardant requirements of polymers and allow their use in specific applications. In this review, the current research status of two-dimensional nanomaterials as flame retardants is discussed, as well as a mechanism of how they can be applied for reducing the flammability of polymers.

“…For the purpose of solving these problems, Tian et al [11] has proposed a novel principle of reversible surfactantenhanced remediation (RSER) based on switchable surfactants. Nowadays, there is a growing attention on switchable surfactants, and it has been found that the aggregation and disruption of the micelles can be reversibly controlled by means of CO 2 /air, electrochemical, photochemical and acid-base changes [12][13][14][15][16][17][18].…”

For the purpose of studying the potential of a novel nonionic switchable surfactant, 11-ferrocenylundecyl polyoxyethylene ether (FPEG), applied to surfactant-enhanced remediation (SER), the surface properties and micelle solubilization behavior of FPEG were investigated with different inorganic salts. With the addition of inorganic salts (NaCl and CaCl 2 ), the critical micelle concentration (CMC) of FPEG dropped from 15 to 12 and 8 mgÁL -1 , respectively, due to the salting-out effect on the alkyl chain. Thermodynamic parameters based on the CMCs indicated that micelle formation was an entropydriven process. Dynamic light scattering measurements verified that these inorganic salts can decrease the hydrodynamic diameters (D h ) of the micelles. Solubilization experiments with three typical polycyclic aromatic hydrocarbons (PAHs) demonstrated that the system of FPEG with NaCl shows the highest solubilization ability, and the molar solubilization ratio and micelle-water partition coefficient (K m ) values follow the order pyrene [ phenanthrene [ acenaphthene. After oxidation, PAHs can be released from the micelles through breaking up of the micelles, and the cumulative release efficiency of pyrene, phenanthrene and acenaphthene are 31.2, 42.8 and 44.6 %; the order of release efficiency is opposite to that of the reduced form for solubilization abilities. All the results suggest that the ferrocene-containing, redox-active surfactant FPEG has the potential to be recycled in SER technology through electrochemistry approaches.

“…Literature data confirmed that clays play at least two roles when used to modify electrodes. They can act as catalyst supports or have the primary role in catalyzing reactions at the surface of electrodes [8][9][10][11][12]. The ability of smectites to exchange cations enables the intercalation of catalytically active species.…”
