Multifunctional liquid-like magnetic nanofluids mediated coating with anticorrosion and self-healing performance.

The long-term protective efficacy of organic coatings against corrosion can be diminished by the presence of micropores/cracks and poor self-healing capabilities. To address these issues, TiC MXene was subjected to liquefaction-like treatment to maintain a two-dimensional lamellar structure in water and polymer matrix for a long time, as well as improve the dispersion stability and loading capacity of MXene. The inorganic corrosion inhibitor ferroferric oxide (FeO) was then electrostatically loaded onto MXene nanofluids to obtain a hybrid material.
