A novel strategy of radical polymerization of sodium 4-styrenesulfonate (NASS) on the surface of carbon black (CB) in solid state is developed to prepare water-dispersible carbon nanoparticles (PNASS-CB).A high performance of natural rubber latex (NRL)/PNASS-CB composite is gained by latex compounding technique.Proton nuclear magnetic resonance (1H-NMR) results show the presence of PNASS chains on the surface of CB
and the encapsulating ratio is 8.1 wt% and grafting ratio is 2.5 wt% by TGA.The surface energy of PNASS-CB was decreased
the interaction between carbon black was weakened
and the carbon-rubber interaction was enhanced.And the carbon nanoparticles are uniformly dispersed in the composite as the result of RPA.When compared to the NRL/pristine CB composite
the tear strength
tensile strength and elongation at break of the obtained composite are increased by 85%
