Ti3C2Tx@CNF nanohybrid improving the corrosion resistance of waterborne epoxy coating under 15 MPa alternating hydrostatic pressure
Cellulose nanofiber was grafted on Ti 3 C 2 T x (Ti 3 C 2 T x @CNF) and then Ti 3 C 2 Tx@CNF nanohybrid acted as nanofiller to endow epoxy coating superior barrier property. Electrochemical tests and corrosion products revealed that incorporation of Ti 3 C 2 T x @CNF into epoxy could significantly improve its anti-corrosion performance. Even immersion in marine alternating hydrostatic pressure (AHP) environment for 240 h, the impedance modulus of composite coating was one order of magnitude higher as compared with controlled samples. Besides, cross-sectional structure confirmed that Ti 3 C 2 T x @CNF remarkable improve the compactness of coating and thus conferring active adhesion strength with twice higher than that of pure epoxy after 240 h immersion in AHP.
