| Abstract Scope |
Tailoring thermal transport by structural parameters could result in mechanically fragile and brittle networks. An indispensable goal is to design hierarchical architecture materials that combine thermal and mechanical properties in a continuous and cohesive network. A promising strategy to create such a hierarchical network targets additive manufacturing of hybrid nanoporous ceramic voxels. Here we describe the convergence of agile additive manufacturing of porous hybrid voxels to tailor hierarchically and mechanically tunable ceramic objects. Additive strategy for achieving mechanical strength and thermal insulation involves the versatile orthogonal surface hybridization of nanoporous silica voxels retains its low thermal conductivity of 19.1 mW m−1 K−1, flexible compressive recovery strain (85%), and tailored mechanical strength from 71.6 kPa to 1.5 MPa. The printed lightweight high-fidelity ceramic objects promise thermal aging mitigation, providing a thermal management pathway using 3D printed ceramic objects. |
