the use of crude carbon dots as novel antioxidants for natural rubber,the ccds could effectively improve the anti-aging performance of the rubber composites. natural rubber (nr) is acknowledged to be a strategically important material, which spans multiple applications from tires to shock absorbers, generally, the antioxidant is indispensable for nr to prolong the service life and improve the long-term reliability.
rubber antioxidants and their transformation products mdpi
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.

dark brown to dark violet pastilles relative density of 0.986-1.00. soluble benzene, acetone, ethyl acetate, toluene dichloromethane and slightly soluble in ether, do not dissolve in water. provides powerful and antioxidant properties with excellent high temperature and
environmental chemical rubber antioxidants,many previous studies have noticed the degradation of antioxidants through the o 3 oxidation, since the most observed tps of antioxidants contains the quinone group and they showed high toxicity. antioxidants and their tps have been released into the environment, and may lead to adverse impacts on the local biota and even human health.
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- Can antioxidant 2246 be grafted to SIO 2?
- Zhong et al. proposed a novel solid-phase method to graft the antioxidant 2246 on the surface of SiO 2 with the aid of a silane coupling agent . The as-prepared SiO 2 -s-2246 performed better than pristine antioxidant 2246 in protecting rubber from thermo-oxidative aging because of the elimination of the “blooming” defects.
