Title : Fast Gelation of MXene Induced by Metal Ions
Abstract:
Hydrogels based on 2D transitional metal carbides and nitrides (also known as MXenes) are biphasic materials made of porous, permeable, and robust solids as well as water, showing a wide range of applications, spanning from electronics, electromagnetic interference shielding, and energy storage, to catalysis, sensing, and biomedicine. This project focuses on an innovative synthetic route to attain MXene hydrogels via a metal ion-induced gelation process. Materials processing was done through diverse deposition techniques (e.g., spray coating, vacuum filtration, blade coating). Moreover, the study also covers the production of aerogels, obtained by the freeze-drying approach starting from the corresponding hydrogels. We explored the effects of different metal ions on MXenes hydrogels and aerogels and investigated their enhanced/innovative properties and performance. In this regard, we capitalized on a long list of multiscale characterization techniques, such as rheological measurement, scanning electron microscopy, and conductivity. The focus was also laid on the potential applications of MXene hydrogels and aerogels in different fields, such as air filtration, bioelectronics, and sensing.
