摘　　要：In this study,the effect of reduced graphene oxide(RGO)on the electrical conductivity and piezoresistivity of natural rubber(NR)/graphene foam(GF)composites was investigated.The RGO suspension(2 g/L)used was prepared via modified Hummers method,and the washed polyurethane(PU)sponges(3 mm×7 mm×50 mm)were immersed in it and then dried in an oven at 80℃.The immersion/drying process could be repeated(1-4 times)to prepare RGO@PU sponges with different RGO dipping times.Then the dried RGO@PU sponges were moved to the ethanol flame(inner flame)for tens of seconds to obtain the GF.
