Abstract:

This dataset reports the values used to calculate initiator concentration and density from the modified to the pristine carbon hard spheres (CHSs). Values used to calculate the polymer graft density on the CHSs for polystyrene and poly(methyl methacrylate) are reported. The values for calculating the thickness of polystyrene and poly(methyl methacrylate) grafted files obtained from high-resolution transmission electron microscopy are provided. Finally the values for bulk density of polymers and the molecular weight of grafted polymers are provided.
