A reversible addition–fragmentation chain transfer (RAFT) agent, 2-{[(dodecylsulfanyl)carbonothioyl]sulfanyl}propanoic acid (DSCTSP), was immobilized on the hydroxyl-functionalized carbon black (CB) surface via a direct condensation reaction, producing CB–DSCTSP. Then, RAFT polymerizations were carried out on carbon black surface using the CB–DSCTSP as a chain transfer agent. Poly(N-isopropylacrylamide)...
Polystyrene, poly(styrene-co-maleic anhydride), poly[styrene-co-(4-vinylpyridine)] and poly(4-vinylpyridine) with well-defined molecular weights and polydispersities were synthesized using 4-hydroxyl-2,2,6,6-tetramethylpiperidin-1-oxyl (HTEMPO)-mediated radical polymerization initiated by azobisisobutyronitrile or benzoyl peroxide. The resultant polymers were grafted onto carbon black surface through...
Core–shell carbon black nanoparticles were prepared by surface-initiated ring-opening polymerization of ε-caprolactone. 1 H NMR, 13 C NMR, FT-IR, TGA, AFM, TEM and dynamic light scattering were used to characterize the core–shell carbon black nanoparticles (CB-g-PCL). TEM and AFM measurements showed that CB-g-PCL formed the core–shell structure with carbon black as the “core” and the...
