A novel waterborne epoxy coating with anti-corrosion performance under harsh oxygen environment

Sustainable Mass Production of Ultrahigh-Aspect-Ratio Hexagonal Boron Nitride Nanosheets for High-Performance Composites

“…For the composites, the peak at 2θ = 26.8° is assigned to the (002) plane of hBN . The results reveal that the composites have crystalline phases, and BNNSs and epoxy matrix form a cross-linking structure. − This can explain the improvement of hydrophobicity for the composites due to the OH groups having transformed into hydrophobic through a cured cross link with epoxy. Recently, Wang and Shioya et al , found that the diffraction peak intensity of G was positively correlated with the concentration of the (002) planes, following Bragg’s equation at 2θ = 26.4°.…”

“…51−54 This can explain the improvement of hydrophobicity for the composites due to the OH groups having transformed into hydrophobic through a cured cross link with epoxy. Recently, Wang and Shioya et al 51,52 found that the diffraction peak intensity of G was positively correlated with the concentration of the (002) planes, following Bragg's equation at 2θ = 26.4°. When G is ordered to align perpendicular to the diffraction direction, most (002) planes can create a diffraction peak, leading to the strong diffraction intensity at 2θ = 26.4°.…”

High-compact MXene-based coatings by controllable interfacial structures

“…As expected, the SZ of the OMC coating is much higher than that of most of the randomly distributed modified BN/EP 34–37 and G/EP 38–43 composite coatings. Interestingly, the SZ of the OMC coating is slightly lower than that of the self-aligned G/EP composite coatings, 25,26,44–47 which is mainly attributed to the inherently complete impermeability of graphene itself or the extra addition of corrosion inhibitors. Additionally, the F-graphene is becoming an attractive route to enhance the anticorrosion performance, 48 due to its superior antipermeation and adjustable conductivity.…”

“…As expected, the SZ of the OMC coating is much higher than that of most of the randomly distributed modified BN/EP [34][35][36][37] and G/EP [38][39][40][41][42][43] composite coatings. Interestingly, the SZ of the OMC coating is slightly lower than that of the self-aligned G/EP composite coatings, 25,26,[44][45][46][47] which is mainly attributed to the inherently complete impermeability of graphene itself or the extra addition of corrosion inhibitors.…”

“…The damage degree of coatings can be evaluated by the breakpoint frequency ( f b , the frequency at 45°phase angle). 47,50 Fig. 4E shows the changes in f b values of the coatings with immersion time, and the detailed parameters are summarized in Table S1.…”
