The field of materials science keeps evolving and we are observing a major shift in materials research from exploring traditional material classes (metals, ceramics, polymers, semiconductors) to programmable, computer-guided discovery and sustainable chemical synthesis and assembly of nanomaterials. 0D, 1D and 2D nanoparticles can be used as building blocks for developing multifunctional 3D nanocomposite structures and devices. In particular, 2D materials can be densely packed like bricks in a wall or incorporate into polymer, metal or ceramic matrices to achieve properties that bulk material can provide.<br/>MXenes are a family of two-dimensional transition metal carbides and nitrides first discovered in 2011. MXenes are solution processed, allowing for the scalability of synthesis to meet real world demand. They have high strength and aspect ratio, combining this with highly active surface chemistry and metallic conductivity. Composites can be designed to have a variety of bridging mechanisms (e.g., ionic, covalent, hydrogen bonding) to make them tough, with tunable mechanical and electrical properties. MXenes offer a wide variety of functionalities that can be integrated into polymer matrices to make functional nanocomposites. High conductivity, electrochemically active surface and excellent electromagnetic interference (EMI) shielding effectiveness have shown success in composites in a wide range of applications (e.g., conductive films, strain sensors, electrochemical energy storage, electrochemical sensing, actuators, EMI shielding, etc.). The combination of ease of processing, mechanical, optical and electric properties, and degree of functionality make MXenes promising for multifunctional polymer nanocomposites.
