Carbon Black (CB) was studied as PVC filler . The tensile strength of CB-PVC composites increasedwith the amount of CB until 15 wt%, then decreased, but elongation at break decreased with increasing CB-content . Nanostructured materials are frequently used ascomposite reinforcing additives . Han Wanget al. made multilayer graphene (MLG)-PVC composites. This composite has higher tensile modulusand glass transition temperature, but lower tensile strength andthermal stability .
