Study on the friction properties of nanocopper oxide/fluorosilicone rubber

Abstract

In order to study the effect of nanocopper oxide (n-CuO) on the friction properties of fluorosilicone rubber (FVMQ), the mechanical blending method was used by adding n-CuO in preparation of FVMQ. Characterization of scanning electron microscopy, X-ray diffraction analysis, energy dispersive spectroscopy, and so on were utilized for studying the mechanism of n-CuO in FVMQ. The experimental test on tensile, tear, and friction performance were performed on n-CuO/FVMQ at both room temperature (RT) and 200 C. In comparison with n-CuO /FVMQ, the wear depth of FVMQ increased by 52.933 and 5.605 μm for RT and 200 C, respectively. Besides, the wear loss of FVMQ increased by 2.9 and 5.3 mg, respectively. The results show that for both at RT or 200 C, the addition of n-CuO changes the friction mechanism of FVMQ. The friction coefficient and wear loss of FVMQ are effectively reduced, so that the friction property of rubber matrix is significantly enhanced. In addition, the tearing property of FVMQ is improved by adding n-CuO to change the crosslinking density of FVMQ.

Fluorosilicone Composites with Functionalized Graphene Oxide for Advanced Applications

“…Regarding the results of the abrasion resistance tests, the addition of any type of filler decreases the abrasion resistance of the rubber matrix, 44 and this loss is dependent on the amount of filler added. The nanocomposites containing 1 phr were those with a higher abrasion resistance index (ARI).…”

“…7 The addition of nanoadditives can reduce friction and wear due to the presence of rolling friction instead of sliding friction. 8,9 Various nanomaterials, such as metals (Ag, Cu), 10,11 metal oxides (CuO, TiO 2 ), 12,13 and inorganic substances (SiO 2 , MnO 2 ), 14,15 have been investigated as base oil additives and found to have an excellent friction reduction and antiwear behavior. Among these additives, carbon-based materials have attracted great attention on account of the advantages of their special structure, stable chemical properties, thermal conductivity, biocompatibility, and small environmental impact.…”
