Ti3C2@ZnO-reinforced interpenetrating polymer network coating toward harsh wear/corrosion protection

To advance the concept of organic-inorganic hybrids toward extreme operating conditions, the composite coating was constructed via adding well-dispersed Ti 3 C 2 @ZnO heterostructure into interpenetrating polymer network (IPN). Its wear rates after UV irradiation under dry and tribocorrosion conditions were decreased by 81.85% and 80.4%, respectively, and accompanied by the highest open circuit potential value. Its storage modulus and adhesion strength after UV irradiation were enhanced by 74.4% and 502.5%, respectively. Outstanding wear/corrosion resistance under extreme operating conditions can be attributed to as follows: the nature/structure advantage of Ti 3 C 2 @ZnO reinforcement including weakening photo-oxidative degradation and good barrier, the mending effect of Ti 3 C 2 @ZnO for wear scar and the formation of tribo-film on the sliding interfaces for preventing the tribo-pairs from direct contact.
