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 - stacking but also exhibit intermolecular interactions with PP through the grafted PP chains.
