AB  - MXene flakes shows the great potential in corrosion protection area owing to 
      their lamellar structure and remarkable mechanical features. However, these 
      flakes are highly susceptible to oxidation, which results in their structure 
      degradation and restrict their application in anti-corrosion field. Herein, 
      graphene oxide (GO) was used to functionalize Ti(3)C(2)T(x) MXene through TiOC 
      bonding to fabricate GO-Ti(3)C(2)T(x) nanosheets, which proved by Raman, X-ray 
      photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy 
      (FT-IR). GO-Ti(3)C(2)T(x) nanosheet inclusion into the epoxy coating and their 
      corrosion performance in 3.5 wt.% NaCl solution with 5 MPa pressure was evaluated 
      through electrochemical techniques including open circuit potential (OCP) and 
      electrochemical impedance spectroscopy (EIS) along with salt spray. Results 
      indicated that GO-Ti(3)C(2)T(x)/EP presented superior anti-corrosion capability, 
      the impedance modulus at low frequency (|Z|(0.01 Hz)) was above 10(8) Omega cm(2) 
      after 8 days' immersion in 5 MPa environment, which was 2 orders of magnitude 
      higher than that of the pure epoxy coating. Scanning electron microscope (SEM) 
      and salt spray images demonstrated that the epoxy coating loaded with 
      GO-Ti(3)C(2)T(x) nanosheet could provide robust corrosion protection for Q235 
      steel via the physical barrier effect.
