DENKA BLACK/polystyrene nanocomposites (DB/PS) were successfully prepared through a facile strategy. Some of the styrene molecules were grafted and polymerized onto the surface of the DB via the in situ free radical addition process in ionic liquid, and others selfpolymerized and coated on the polystyrene grafted DB. The ionic liquid improves the grafting percentage because of its high viscosity. The electrical properties of polymer composites before and after the grafting were measured. It was found that the electrical conductivity of the DB/PS composites decreased with increasing amounts of monomer styrene and initiator 2, 2′-azobis (isobutyronitrile) (AIBN). The microstructure, morphology and thermal properties of the composites were characterized by Fourier transforminfrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy. The results proved that the polystyrene had been successfully grafted onto the DB surface.

“…Thus it can be concluded that NbSe 2 nanofiber assists in increasing the carrying capacity of the tribo-system under dry sliding friction conditions. When the variable velocities are applied, the anti-friction effect becomes better as the NbSe 2 nanofiber content increases [5]. The reason for this reduction in the coefficients of friction could attribute to the NbSe 2 lubricant layer at the counter-faces of the wear sample (the following EDS of figure 8b, c).…”

Copper matrix solid self-lubricant composites were prepared by powder metallurgy route using copper powders and NbSe 2 nanofiber or sheet. The tribological properties of the as-prepared materials were estimated by a ball-on-disc on UMT-2 multi-function friction and wear tester under dry conditions in a normal laboratory atmosphere (55-70% relative humidity, 15-25 °C). The NbSe 2 nanofiber or sheet was very effective in improving the tribological properties of the composites. It is found that the composites with 15 wt.% NbSe 2 nanofibers showed a very low coefficient of friction of 0.1487. Furthermore, the value levels of electrical resistivity for the composites with different contents of NbSe 2 nanofiber reached to 10 -6 Ω.cm. When the NbSe 2 content was high enough, a continuous supply of NbSe 2 nanofiber to the tribo-surface is an important precondition and the benefit of its anti-friction properties for the copper matrix composites. This behavior is related that little NbSe 2 is reacted with the Cu-base in the sintering process, although there needs enough NbSe 2 nanofibers as solid lubricants; too much NbSe 2 nanofibers will decrease the intensity of the composites, reducing the wear resistance. So adding the appropriate contents of NbSe 2 nanofiber to the composites play an important role in anti-friction and wear resistance.

“…It has been indicated that the coefficient of friction of the composites decreased with increase in the volume fraction of reinforcements [25,26,50,67,68]. The coefficient of friction of aluminum matrix composite reinforced with CNTs decreases with increasing volume fraction of CNTs in the composite as shown in Fig.…”

Metal matrix composites (MMCs) are an important class of engineering materials that are increasingly replacing a number of conventional materials in the automotive, aerospace, marine, and sports industries due to their lightweight and superior mechanical properties. In MMCs, nonmetallic materials are embedded into the metals or the alloys as reinforcements to obtain a novel material with attractive engineering properties, such as improved ultimate tensile strength, ductility, toughness, and tribological behavior. In this chapter, an attempt has been made to summarize the tribological performance of various MMCs as a function of several relevant parameters. These parameters include material parameters (size, shape, volume fraction, and type of the reinforcements), mechanical parameters (normal load and sliding speed), and physical parameters (temperature and the environment). In general, it was shown that the wear resistance and friction coefficient of MMCs are improved by increasing the volume fraction of the reinforcements. As the normal load and sliding speed increase, the wear rate of the composites increases and the friction coefficient of the composites decreases. The wear rate and friction coefficient decrease with increasing temperature up to a critical temperature, and thereafter both wear rate and friction coefficient increase with increasing temperature. The nano-composites showed best friction and wear performance when compared to micro-composites.
