PBR Nanocomposites R einforced by Graphene Nanosheets:Investigation of Cure and Mechanical Properties

This research is regarding the preparation of cis-۱,۴-polybutadiene rubber (PBR)/graphene nanosheets(GNSs) nanocomposites by in-situ polymerization process. The rheometer torque values showed the effectof GNSs in improving the scorch safety of the nanocomposites. When the GNSs content was increased, thenanocomposites showed excellent tensile properties which was attributed to the nanometer scale dispersionand stronger interactions between GNSs and PBR chains. There was approximately ۵۵ % improvement intensile strength when ۱.۰ wt. % of GNSs was added to the matrix. The above results show that in-situpolymerization will improve the dispersion and final properties of the PBR nanocomposites.
