“…In our previous work, [31,32] we briefly reported a novel process to prepare NRL/CB nanocomposites by combining latex compounding and self-assembly techniques. Similarly, the NRL/PNASS-CB composite was prepared according to the following procedures.…”

“…[31,32] The absorbed NASS was polymerized and grafted onto the CB surface. The modified CB (PNASS-CB) could retain nano-dimensions (about 90 nm), much less than the pristine CB (up to 140 nm) because the water-soluble polymers (PNASS) attached to CB protected the new surface area of CB from the van der Waals attraction of other CB particles.…”

“…[31,32] Here, a thermo-mechanical technique was employed similar to that in the previous research by our group. [33][34][35][36] The modified CB can be homogenously distributed in water with an average size of 90 nm when the diameter of original CB aggregates was up to 140 nm.…”

A novel strategy of radical polymerization of sodium 4-styrenesulfonate on the surface of carbon black (CB) in the solid state was developed to prepare hydrophilic carbon nanoparticles (PNASS-CB). A high performance natural rubber latex (NRL)/PNASS-CB composite was produced by the latex compounding technique. Scanning electron microscope shows considerable improvement in the dispersion of PNASS-CB in rubber matrix. The lower degree of filler-filler networks and the stronger filler-rubber interaction of PNASS-CB in rubber matrix were confirmed by dynamic mechanical thermal analysis. Rheometric properties of NRL/PNASS-CB, like scorch time and optimum cure time, decreased. Tensile strength, tear strength, and elongation at break increased due to stronger interaction between the PNASS-CB and rubber matrix. Dynamic mechanical properties of the modified carbon nanoparticles further corroborated a significant contribution from the better dispersion and efficient load transfer of PNASS-CB on the static and dynamic mechanical properties of composites.

“…Many researchers used advanced processes and equipments to get better dispersion [7][8][9][10]. However, it ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 4 was found that there was only a slight decrease of the particle size of the CBs and little improvement of its dispersion in water [6]. Subsequently, a large number of specific dispersants [11] have been employed to distribute CB particles into various rubbers.…”

A new kind of water-suspensible carbon nanoparticle was prepared by oxidizing carbon black (CB) using aqueous ammonium persulfate (APS) as an oxidant. The obtained water-suspensible carbon nanoparticles (APS-CBs) were still homogeneously distributed in water three weeks after sonication. Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) were employed to characterize the changes of the oxygen containing functional groups on the surfaces of the APS-CBs. Furthermore, a high performance of an epoxidized natural rubber latex (ENRL)/APS-CBs composite was obtained by a liquid latex blending method. The carbon nanoparticles were homogeneously distributed in the matrix. In ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 comparison with the ENRL/pristine CBs composites, the APS-CBs improved the mechanical properties of the ENRL/APS-CBs composites. The dynamic rheological properties were also studied.

Natural rubber filled with poly(sodium-4-styrenesulfonate) (PSS)-decorated carbon black (CB) by employing a latex compounding technique was prepared. The result of scanning electron microscope demonstrated that CB was uniformly dispersed in the matrix. Comparing to traditional dry compounding, an improvement in physical and mechanical properties was observed in the composites attributed to the homogeneous distribution of CB in matrix and an augment of bound rubber. Owing to the changes of the physical properties of CB surface, vulcanizate filled with oxidized CB via latex way exhibited higher mechanical properties. The resulting vulcanizates displayed a diminished interaction between fillers based on the consequence of strain dependence of storage modulus. Furthermore, a splendid wet-skid resistance was obtained in vulcanizates fabricated by latex compounding technique in comparison with vulcanizates prepared by traditional dry compounding.
