  • Does antioxidant 4010na and silica enhance thermo-oxidative aging assistance?
  • In this work, the synergistic effects of antioxidant 4010NA and silica on enhancing thermo-oxidative aging assistance for NR were investigated by experiments and molecular simulations, and the mainly conclusions were generalized as follows:
  • Does antioxidant 4010na play a better protective role in 4010na/sio 2 /nR composite?
  • Of note, antioxidant 4010NA played a better protective role in 4010NA/SiO 2 /NR composite depending on the difference in the carbonyl increase rate for the presence and absence of antioxidant 4010NA, i.e., NR and 4010NA/NR, CB/NR and 4010NA/CB/NR, SiO 2 /NR and 4010NA/SiO 2 /NR.
  • Are carbon dots a rubber antioxidant?
  • Carbon dots as rubber antioxidants The carbon materials, such as carbon black, graphene, fullerene, etc, are well known to be able to retard the aging processes of various polymers including polyolefine, rubber, polyamide, etc., due to the active trapping of radicals .
  • Does antioxidant 4010na reduce FFV and FCV of NR?
  • (1) By means of QM simulation, the protective mechanism of antioxidant 4010NA for NR was elucidated quantitatively from the point of free energy of dissociation and energy barrier of reaction. (2) The addition of silica was capable of reducing FFV and FCV of NR, thereby improving O 2 barrier ability of NR.
