| Abstract Scope |
Building 2D materials into complex 3D micro-architectures can provide superior device performance compared to planar patterned devices. Using two techniques, we arrange 2D nano sheets into well-defined complex 3D device structures without significant restacking. First, Aerosol-Jet nanoprinting is used to stack Ti3C2Tx MXene nanosheets into truly 3D microarchitectures with different geometries, at very high aspect ratios, high printing resolution (~10 μm), excellent size controllability, and smooth surface on various substrates. This technique is critical for the fabrication and application of MXene-based high-performance 3D micro-electronics (e.g. wearable healthcare devices). We then demonstrate the arrangement of such nano sheets via MXene-infiltrated porous silica (MX-PS). Freeze casting is utilized to fabricate a silica backbone with controlled porosity, followed by the infiltration of MXene dispersion to form a 3D network of conformal coating. The assembled sandwich-type supercapacitors demonstrate exceptional areal capacitance (7.24F/cm²) and energy density (0.32mWh/cm²) with just a 6% additional mass from MXene. |
