Conducting Nanocomposite Polymer Foams from Ice-Crystal-Templated Assembly of Mixtures of Colloids



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.
