Abstract

The facile fabrication of polypyrrole (PPy) foams via vapor phase polymerization using microcellular polystyrene, prepared by unidirectional freeze-drying, as a template was demonstrated. Remarkably, the PPy foams maintained the porous morphology of the template, which exhibited a bamboo-like honeycomb channel structure. In addition, the PPy foams were carbonized at 800 °C with iodine doping and the carbon products showed similar morphologies to that of the precursor. The carbon foams were characterized by Raman spectroscopy and XRD analysis and were confirmed to be amorphous carbon with a nitrogen content of about 7%.
