Ti₃C₂T_x MXene Polymer Composites for Anticorrosion: An Overview and Perspective

Abstract

As the most studied two-dimensional (2D) material from the MXene family, Ti3C2T x has constantly gained interest from academia and industry. Ti3C2T x MXene has the highest electrical conductivity (up to 24,000 S cm–1) and one of the highest stiffness values with a Young’s modulus of ∼ 334 GPa among water-dispersible conductive 2D materials. The negative surface charge of MXene helps to disperse it well in aqueous and other polar solvents. This solubility across a wide range of solvents, excellent interface interaction, tunable surface functionality, and stability with other organic/polymeric materials combined with the layered structure of Ti3C2T x MXene make it a promising material for anticorrosion coatings. While there are many reviews on Ti3C2T x MXene polymer composites for catalysis, flexible electronics, and energy storage, to our knowledge, no review has been published yet on MXenes’ anticorrosion applications. In this brief report, we summarize the current progress and the development of Ti3C2T x polymer composites for anticorrosion. We also provide an outlook and discussion on possible ways to improve the exploitation of Ti3C2T x polymer composites as anticorrosive materials. Finally, we provide a perspective beyond Ti3C2T x MXene composition for the development of future anticorrosion coatings.

Novel Strain Engineering Combined with a Microscopic Pore Synergistic Modulated Strategy for Designing Lattice Tensile-Strained Porous V2C-MXene for High-Performance Overall Water Splitting

“…For example, introducing nanoparticles between MXene layers by the intercalation technique could inhibit the re-stacking of sheets and expand the spacing between layers, but nanoparticles could result in the excessive increasement of the spacing . Moreover, the molecular preintercalation could prevent MXene sheets from stacking, while the loss of ions or molecules could cause the collapse of spatial structure during the long-term cycling process . Besides, engaging the sacrificial template method to construct a three-dimensional MXene with porous structure could prevent the stacking of nanosheets and boost the ion migration rate, while the common preparation process is relatively complex …”

“…Corrosion is another concern in MXene-based wearable electronics, especially when exposed to harsh environments or corrosive substances. 50 MXene-based materials, although known for their stability, can still undergo corrosion processes under certain conditions. Corrosion can lead to degradation of the MXene layer, loss of electrical conductivity, and overall device failure.…”
