From: 3D printing of sacrificial templates into hierarchical porous materials
(a) Schematics of the processing route used to fabricate hierarchical porous materials from nanoemulsions and microdroplets (Route 1) (b) SEM images of the porous structure obtained after drying of the soft precursors. (c,d) Size distributions of the µm-templates and the nm-sized droplets (c) before and (d) after drying.
