Conductive polystyrene/carbon nanotube (CNT) microcellular foams were prepared by high internal phase emulsion polymerization technique. In this study, CNT was modified with polypyrrole (PPy) as a conductive polymer to improve the oil phase affinity of high internal phase emulsion and the electrical conductivity of polymerized microcellular foam. The degree of PPy-CNT dispersion was confirmed by the morphology of the prepared foam, and the damage of PPy-CNT caused by the intensity of ultrasonication was confirmed by the electrical conductivity. As the content of PPy-CNT increased, the electrical conductivity increased and the cell size decreased. The degree of PPy-CNT dispersion improved with the intensity and imposed time of ultrasonication, but the electrical conductivity increased only to a certain level. |
