The family of 2D transition metal carbides and nitrides (MXenes) has been expanding rapidly with about 30 different MXenes synthesized to date, such as Ti2C, Ti3C2, Nb2C, V2C, Mo2C, Mo2TiC2, and Nb4C3, and several more theoretically predicted.1 Because of the wet etching synthesis methods, all of the MXenes reported so far have surface functionalities, such as hydroxyl, fluorine, and oxygen, which add hydrophilicity to their surfaces. In addition to water, MXenes can be dispersed in a variety of organic solvents, expanding the possible MXene processing techniques, for example printing, spray and spin coating as well as fabricating hydrogels, and ionogels.2,3 Due to the solution-based processing of MXenes, they are ready to be mixed with other nanomaterials and polymers to form nanocomposites.4 Additionally, MXene surfaces are shown to induce oxidant-free in-situ polymerization when mixed with different polymers such as pyrrole and EDOT.5 In this talk, we will present the processing of MXene solutions and discuss their nanocomposites with different polymers and nanomaterials.
