The research status of reinforcing fillers,such as carbon black,biomass silicon carbon,carbon nanotubes,graphene,silica,silicate and ionic polymer for the composite modification of hydro-genated nitrile rubber was systematically reviewed with 53 references,and the reinforcing characteris-tics of different types of reinforcing fillers for hydro-genated nitrile rubber were introduced in detail.Fi-nally,the development direction of new reinforced fillers was prospected.
