Fabrication of conducting nanocomposite‐ reinforced soft polymer foams is demonstrated. These multicomponent cellular materials are built from a mixture of colloids dispersed in water by freeze–drying, thereby using ice crystals as template for the porous structure. An excluded‐volume effect armors the “soft”‐polymer cell walls with “hard” nanoparticles, thereby enhancing the mechanical robustness of the foams.
