“…In agreement with the EIS results, the epoxy/F-GO@MXene coating exhibits excellent corrosion protection property, and noticeably lower amounts of corrosion products appear even after 60 days of salt spray examination. It should be mentioned that both PE and epoxy/F-GO samples have been studied in our previously published papers …”

“…7−10 Meanwhile, researchers have utilized the advantages of the GO coupled with other inorganic nanomaterials to overcome the GO agglomeration in the organic matrix (because of van der Waals interactions between the GO nanosheets and remarkable specific surface area of the GO), and this strategy has increased the anticorrosion efficiency of the coating systems. 11,12 In this regard, the GO surface is decorated with different inorganic nanomaterials including silica, 13−15 titania, 16−18 and zinc oxide. 19−21 The GO nanosheets are also coupled with other 2D nanosheets such as graphitic carbon nitride, 12 boron nitride, 22,23 and montmorillonites.…”

Herein, layer-by-layer MXene/graphene oxide nanosheets wrapped with 3-aminopropyltriethoxy silane (abbreviated as F-GO@MXene) are proposed as an anti-corrosion promoter for waterborne epoxies. The GO@MXene nanohybrid is synthesized by a solvothermal reaction to produce a multi-layered 2D structure without defects. Then, the GO@MXene is modified by silane wrapping under a reflux reaction, in order to achieve chemical stability and to create active sites on the nanohybrid surface for reaction with the polymer matrix of the coating. The organic coating modified with 0.1 wt % F-GO@MXene has revealed superior corrosion protection efficiency than the organic coatings modified with either F-GO or F-MXene nanosheets. The impedance modulus at low frequency for the pure epoxy, epoxy/F-MXene, epoxy/F-GO, and epoxy/F-GO@MXene coatings is 4.17 × 105, 5.5 × 108, 4.46 × 108, and 1.14 × 1010 Ω·cm2 after 30 days of immersion in the corrosive media, respectively. The remarkable anti-corrosion property is assigned to the intense effect of the nanohybrid on the barrier performance, surface roughness, and adhesion strength of the epoxy coating. The complemental analysis based on first-principles density functional theory reveals that the adhesion strength related to the silane functional groups in its complexes follows the order F-GO@MXene > F-MXene > F-GO. The enhanced stabilization predicted on the GO@MXene nanohybrid ultimately stems from the combined role of the electrostatic and van der Waals forces, suggesting an increase in the penetration path of the corrosive media.

“…[10][11][12] Meanwhile, some researches show that C 3 N 4 has effects on the performance of polymers on mechanical properties, thermal properties, UV-shielding properties, flame retardant properties and dynamic mechanical properties. [13][14][15][16] However, the large surface area of C 3 N 4 makes it easy to stack and aggregate, which limits its application in rubber reinforcement. [17,18] In addition, it is difficult to satisfy the higher and higher demands of rubber industry that incorporating SiO 2 or C 3 N 4 individually to reinforce the performance of rubber.…”

In this work, a series of C 3 N 4 /SiO 2 nanohybrids were prepared and incorporated to solution polymerized styrene-butadiene rubber/butadiene rubber (SSBR/BR) to prepare "green tire" tread rubber. As expected, C 3 N 4 /SiO 2 nanohybrids are uniformly dispersed in SSBR/BR, and SiO 2 possesses a small average particle size of $15 nm. In addition, the interfacial interaction between C 3 N 4 /SiO 2 nanohybrids and rubber matrix are significantly enhanced. Hence, the mechanical properties of C 3 N 4 /SiO 2 -SSBR/BR nanocomposites are greatly improved. The tensile strength of 5% C 3 N 4 /SiO 2 -SSBR/BR nanocomposites (5 wt% C 3 N 4 in C 3 N 4 /SiO 2 ) improved 1580% compared to pristine SSBR/BR. Furthermore, dynamic mechanical analyses indicate the increasing wet skid resistance (10.8% higher) and decreasing rolling resistance (50.5% lower) of 5% C 3 N 4 /SiO 2 -SSBR/BR nanocomposites compared with SiO 2 -SSBR/BR. In addition, the wear volume and heat built-up are reduced at the same time. This work paves the way to prepare high comprehensive performance "green tire" and could be extend to the reinforcement of elastomer composites.
