Abstract Scope |
Inorganic materials with nanoscale feature sizes, hierarchical porosity and controllable architecture are of interest as lightweight structural materials, catalysts, and for thermal and fluid transport. Here, I will present the development of novel two-photon lithography resins that contain metallic nanoclusters which serve as both photoinitiators and inorganic precursors. Using these resins, we demonstrate the additive manufacturing of structures with nano to microscale features with complex geometries and large overhangs, such as buckyballs, helices, and lattices. Through a high temperature pyrolysis step, the as-printed nanocluster-polymer composites are transformed into nanoporous materials with an average pore size of ~50 nm and relative density of ~0.5. The mechanical properties of the as-printed composites materials, and the final nanoporous structures are characterized using nanoindentation-based compression testing, and related to the heterogeneous microstructure. |
