| Abstract Scope |
Building functional nanomaterials into complex three-dimensional (3D) micro-architectures with high aspect ratio can provide superior device performance compared with simple two-dimensional (2D) patterns. Even though functional titanium carbide (Ti3C2Tx) MXene nanosheets have received much attention for energy storage, healthcare, advanced composites, and membranes; arranging them into well-defined complex 3D device structures remains a significant challenge and has not been realized. Among the techniques for building 3D structures, 3D printing is advantageous compared with conventional ones (e.g. lithography) as it allows for flexible customization, rapid prototyping, and minimal waste generation. We report printing of Ti3C2Tx MXene nanosheets into truly 3D microarchitectures with different geometries (including pillar array, wavy-wall array, and scaffold array), 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). |
