Abstract: This paper introduced the preparation technologies of conductive polyurethane foams (PUFs) using different conductive fillers, which included carbon black, carbon nanotubes, graphite, metal, organic fillers, etc. summarized the preparation methods of composite foam with different and the effect of these types of conductive fillers on the properties of PUFs was analyzed, and their application in piezoresistive materials, microwave absorbing materials, electromagnetic shielding materials, and electrode materials was discussed. The analysis results indicated that the introduction of conductive fillers improved the anti-static and conductive phenomenon of PUFs and therefore broadened their application range.
