| Abstract: | Polypropylene‐graft‐reduced graphene oxide (PP‐g‐rGO) was synthesized and used as a novel compatibilizer for PP/polystyrene (PP/PS) immiscible polymer blends. SEM observation revealed an obvious reduction of the average diameter for the dispersed PS phase with the addition of PP‐g‐rGO into a PP/PS (70/30, w/w) blend. The compatibilization effect of PP‐g‐rGO will subsequently lead to the enhancement of the tensile strength and elongation at break of the PP/PS blends. The compatibilizing mechanism should be ascribed to the fact that PP‐g‐rGO can not only adsorb PS chains on their basal planes through π‐π stacking but also exhibit intermolecular interactions with PP through the grafted PP chains. © 2014 Wiley Periodicals, Inc.
