Abstract Scope |
Two photon lithography (TPL) offers a high precision means to create architected materials with arbitrary geometries having the potential to be used as lightweight structural materials. Here, we implement a custom photoresist containing metallic nanoclusters which remain in the printed structures. Further, high temperature pyrolysis of these structures under inert gas is used to produce carbon-metal structures with up to 80% shrinkage compared to the polymeric material. Interestingly, this process produces nano-porous structures. Mechanical properties of both the nano-porous pyrolyzed and as printed polymeric embedded structures are characterized using compression on cylindrical structures. Properties of the polymeric-metal structures are investigated as a function of nanocluster composition. Increases in the volume fraction of metallic nanoclusters leads to improvements in the mechanical properties. Pyrolyzed structure mechanical properties are studied as a function of both nanoporous percentage and pyrolysis parameters. The mechanical properties of porous architected lattices are evaluated. |
