Hindered phenol functionalized graphene oxide (HPFGO) was prepared by grafting 2,6-Di-tert-butyl-4-hydroxymethyl phenol (DBHMP) onto graphene oxide (GO) using isophorone diisocyanate as bridging agent. FT-IR, XPS, XRD and TGA results confirmed the chemical structure of HPFGO. By latex-mixing method, HPFGO was uniformly dispersed in natural rubber (NR) matrix and obviously enhanced the thermal stability...
Due to low thermal stability, poor migration, and extraction resistances, the antioxidant with low molecular weight is easy to physically lose during processing and long‐term service, and its applications are severely restricted. To increase the molecular weight of antioxidant is one of the promising methods to overcome such drawbacks. In this study, the extraction resistance of a macromolecular antioxidant,...
