A review on recent advances in 2D-transition metal carbonitride-MXenes nano-sheets/polymer composites' electromagnetic shields, mechanical and thermal properties

As of today, plenty number of novel and efficient nanomaterials have been introduced, manufactured, and investigated to improve the particular characteristic of the materials, i.e., polymers, making them advanced. Among these nanomaterials, 2-Dimansion (2D) MXenes sheets, a modern category of particles, have been famous due to their tremendous functionalities and capabilities to be utilized in composites. MXenes show remarkable potential in thermal, mechanical, and magnetic fields resulting from their unique microstructure. Therefore, it has been at the center of scientists' attention during this decade. MXenes are being used in various fields such as sensors, biology, water purification, supercapacitors, batteries, photocatalysts, energy storage materials, transparent electrodes, electrochromic materials, triboelectric nanogenerators, photodiodes, composites, etc. Numerous investigations are conducted to explore how MXenes ‘composites get improved during the introduction of these particles into the polymeric matrix, as well as, what is the mechanism of thermal, mechanical, and magnetic properties enhancement in the presence of MXenes. Herein, after a brief introduction of MXene particles and the methods to produce them, the mechanism of being effective in either magnetic, mechanical, or thermal properties in composites is explained, followed by the recounting of the findings of the researchers in MXene/polymer composites. Achievements have shown that electromagnetic waves can be avoided by the composites containing MXenes. In addition, due to the strong interactions between the polymeric chains and MXenes, the mechanical properties of the composites can be significantly improved.
