Two-dimensional Ti3C2Tx flakes have great application potential in various areas due to their optical,electronic,electrochemical and mechanical properties,but their anti-corrosion and wear-resistance per-formance were not well understood.The difficulties in achieving good dispersity and interface interaction of inorganic additives in organic coatings hinder the incorporation of Ti3C2Tx into the epoxy coating.Here,few-layered Ti3C2Tx sheets with amino-functionalization were prepared,and as reinforced-additives were added into the waterborne epoxy coating.Anti-corrosion and tribological properties of as-prepared composite coatings were investigated in detail.The results reveal that the composite coating with 0.5 wt.％ amino-functionalized Ti3C2Tx sheets shows excellent corrosion protection (the lowest frequency impedance was 3.12 × 109 Ω cm2) and wear resistance (wear rate was reduced by 72.74％).The greatly improving performance of composite coatings mainly depends on:(a) good dispersity and compatibility of amino-functionalized Ti3C2Tx in organic matrix,(b) high adhesion strength between coating and metal substrate and (c) the intrinsic properties ofTi3 C2Tx sheets.The work provides a good path for applications of MXene as multifunctional additives.
