Fibrous carbon nanotubes (CNTs) and lamellar graphene oxide (GO) exhibit significant advantages for improving the fatigue properties of rubber composites. In this work, the synergistic effect of CNTs and GO on the modification of the microstructure and fatigue properties of natural rubber (NR) was comprehensively investigated. Results showed that CNTs and GO were interspersed, and they formed a strong filler network in the NR matrix. Compared with those of CNT/NR and GO/NR composites, the CNT-GO...

The topology of nanofillers is one of the key factors affecting the gas barrier properties of rubber composites. In this research, three types of carbon-based nanofillers, including spherical carbon black (CB), fibrous carbon nanotubes (CNTs), and layered graphene (GE) were chosen to investigate the effect of the topological structures of nanofillers on the gas barrier properties of styrene-butadiene rubber (SBR) composites. Results showed that the structure and strength of the filler networks i...

Abstract The high gas barrier property of a rubber composite is of great significance for reducing the exhaust gas emissions due to tire rolling resistance and hence the contribution this factor makes to environmental protection. Enhanced covalent interfaces and crosslinked networks are crucial to the gas barrier property of rubber composites. In this research, γ-mercaptopropyltriethoxysilane (MPS) modified GO (MGO)/styrene-butadiene rubber (SBR) composites were prepared by a synergetic strategy...

Abstract Constructing strong interfacial interactions and complex filler networks is crucial to establishing high gas barrier properties in rubber composites. In this research, sulfur-graphene oxide (S-GO) hybrids were prepared by in situ growth of sulfur on the surfaces of GO sheets. The S-GO hybrids were also introduced into butadiene styrene rubber (SBR) using a green method of latex compounding. Results showed that sulfur could melt and spread on the surface of the GO during the crosslinking...

Abstract Obtaining a homogeneous dispersion of graphene in a rubber matrix by efficient melt blending is a great challenge presently faced by the rubber industry. In this study, graphene oxide (GO)-supported zinc oxide (ZG) hybrids were prepared by electrostatic adsorption and in situ growth methods. Subsequently, ZG hybrid/chloroprene rubber (ZG/CR) composites were fabricated by the traditional method of melt blending. The results revealed that the ZnO nanoparticles were adsorbed on the surface...

Abstract Protection against sulfur mustard (HD) is essential for the safety of the operators in the lab and in war. In this research, graphene oxide/butyl rubber (GO/IIR) composites were first prepared by a green method of latex compounding. This method achieved uniform dispersion of GO in IIR matrix for the GO content up to 2 phr (parts per hundreds of rubber). More importantly, there was a strong interfacial interaction between GO and IIR chains. When the GO content was 2 phr, the tear and ten...

In this research, graphene oxide (GO) and silica reinforced styrene-butadiene rubber (SBR) composites were prepared by compounding GO/SBR masterbatch with silica. The influence of GO on the evolution of the filler network and crosslinking network of the composite during the fatigue process was investigated. Furthermore, the fatigue lifetimes of composites with different GO contents were obtained. The results showed that the GO sheets had a fine dispersion in the SBR matrix. The filler network co...
