“…The frictional heating leads thermal degradation of rubber and change in wear behavior during a long period of sliding. The tribological behavior of fluororubber (FKM) O-rings were traced by tribo-test and compared at different stages of the wear process [305]. Results showed that under the influence of thermal degradation of FKM, the wear rate and friction coefficient decreased, while the friction instability increased, associated with the wear tongue development.…”

Fluororubber (FKM) has an important application in the industrial field. However, the coloring problem of FKM has always affected the performance of its mechanical properties. Herein, a novel silicon dioxide (SiO2) colored with acid orange 7 (AO7) was prepared by sol-gel method to ameliorate the mechanical properties and coloring property of FKM. Acid orange silica sol was prepared by adding AO7 to sodium silicate solution, and then colored SiO2-AO7 was prepared by freeze drying. The effects of SiO2-AO7 modified FKM on mechanical properties, thermal conductivity and coloring were systematically studied. The results show that SiO2-AO7 has the advantage of enhancing the mechanical properties of FKM without affecting its color appearance. Relative to the unmodified FKM, the tensile strength and modulus at 300% elongation saw enhancements of 47.2% and 21.8% respectively. The SiO2-AO7 offers exceptional coloration and mechanical reinforcement, showing strong suitability for industrial application.

The thermal conductivity of fluoroelastomer is a critical factor influencing the stability and lifespan of Viton seals utilized in harsh environments characterized by high temperatures and pressures. While the incorporation of carbon nanotubes (CNTs) into fluoroelastomers presents a promising solution, their tendency to agglomerate has hindered enhancements in thermal conductivity. To address this issue, a uniform thermal conductivity network was developed by incorporating modified carbon nanotubes into the Viton matrix. This innovation facilitated rapid heat transfer within Viton products, preventing potential failures caused by uneven internal heat distribution. After modification, carbon nanotubes with amino functional groups were uniformly dispersed within the fluorine rubber, overcoming agglomeration. They were also involved in crosslinking with the rubber, resulting in a network that improved the composite material's thermal conductivity efficiency by 42% and mechanical strength by 14%. Viton seals, designed with modified carbon nanotubes incorporated as a network, exhibited good thermal conductivity, offering a viable solution for extending the lifetime of Viton seals under harsh conditions.Highlights Hybridization modification of carbon nanotubes.
