Technical Field

Background
The dispersibility and compatibility of the two-dimensional nanofiller in the polymer matrix directly determine the corrosion protection properties of the polymer composite coating. The poor dispersibility can cause the agglomeration phenomenon of the nano-filler, and the advantage of the two-dimensional nano-filler is difficult to be exerted; poor compatibility can cause the defects of peeling, microcracks, holes and the like at the interface between the polymer matrix and the filler, and can accelerate the corrosion rate of the composite coating. Compared with graphene which is easy to agglomerate, the surface of the titanium carbide nanosheet is rich in oxygen-containing functional groups and easy to disperse. However, for the titanium carbide nanosheets, the lamellae are aggregated together due to strong van der waals forces, which greatly weakens the physical barrier effect of the lamellae. The nano-cellulose can be used for well modifying and dispersing the agglomerated titanium carbide nano-sheets, and simultaneously, the compatibility between the nano-sheets and resin can be promoted. Therefore, it is an urgent problem to provide a high-performance water-based anticorrosive coating.
