Improving the Dynamic Mechanical Properties of XNBR Using ILs/KH550-Functionalized Multilayer Graphene.

Graphene has been considered an ideal nanoscale reinforced phase for preparing high-performance composites, but the poor compatibility and weak interfacial interaction with the matrix have limited its application. Here a highly effective and environmentally friendly method for the functionalization of graphene is proposed through an interaction between as-exfoliated graphene and (3-aminopropyl) triethoxysilane (KH550), in which 1-butylsulfonate-3-methylimidazolium bisulfate (BSOHMIm)(HSO) ionic-liquids-modified graphene was prepared via an electrochemical exfoliation of graphite in (BSOHMIm)(HSO) solution, then (BSOHMIm)(HSO)-modified graphene as a precursor was reacted with amine groups of KH550 for obtaining (BSOHMIm)(HSO)/KH550-functionalized graphene. The final products as filler into carboxylated acrylonitrile‒butadiene rubber (XNBR) improve the dynamic mechanical properties.
