Abstract 2D titanium carbide (Ti 3 C 2 T x MXene) has potential application in flexible/transparent conductors because of its metallic conductivity and solution processability. However, solution‐processed Ti films suffer from poor hydration stability mechanical performance that stem the presence intercalants, which are unavoidably introduced during preparation suspension. A proton acid colloidal processing approach is developed to remove extrinsic intercalants film materials, producing...

Ultralight, ultrastrong, and supertough graphene aerogel metamaterials combining with multi-functionalities are promising for future military domestic applications. However, the unsatisfactory mechanical performances lack of multiscale structural regulation still impede development aerogels. Herein, we demonstrate a laser-engraving strategy toward meta-aerogels (GmAs) unusual characters. As prerequisite, nanofiber-reinforced networks convert walls' deformation from microscopic buckling to...

The hydrogel matrix normally forms via covalent or noncovalent interactions that make the resistant to hydration and disassembly. Herein this type of chemical transition is demonstrated in titanium carbide MXene (Ti3C2Tx), which exchange intercalated Li+ with hydrated protons triggers significantly suppressed stacked Ti3C2Tx. Based on intercalation chemistry behavior, pristine Ti3C2Tx matrices an arbitrary microstructures are fabricated by freezing-induced preassembly a subsequent specially...
