“…Its contact area is smooth, which can be further proven by the SEM images (Figure b). The wear mechanism of copper‐SI with applied a voltage (0.1 and 0.5 V) is consistent with the oxidation wear, and the accelerated surface oxidation prevents the copper located in the contact area from slipping and breaking, thereby resulting in copper friction …”

Porous copper/graphite composites storing stimuli-responsive lubricant can be used to fabricate a new kind of electrical contact friction materials. However, the synergetic lubricating effect of solid and liquid lubricants incorporated into the copper matrix is rarely discussed. In this work, neat copper and its composites storing ionic liquids (ILs) have been successfully prepared via a template-free strategy. The effect of frictional, electrical, and electro-frictional coupling stimulation on the tribological behavior of the copper filled with graphite has been investigated using ball-on-disk friction tests. Results show that a high voltage may accelerate the release of the ILs stored in the composite to the friction interface, thereby resulting in a low coefficient of friction (COF) (ca. 0.14) at the voltage of 0.5 V, which is superior to those of the pure copper without applying voltage. The COF is more stable in copper/graphite composite storing ILs (SI) than in copper-SI. Therefore, the graphite efficiently protects the surface of the sample from wear and electrochemical corrosion.

“…Hence, it can be concluded that nano-SiO 2 particles are dispersed homogeneously into PI matrices with this polymerization method, even at higher nano-SiO 2 content of 20 wt%. The homogenous dispersion of nano-SiO 2 particles may be associated with the better interaction between monomers and nanoparticles with the existence of coupling agents [17], as well as PAA to facilitate the segregation of nanoparticles for the fabrication of such composites [18].…”

Polyimide (PI)/nano-SiO 2 composites were successfully fabricated via a novel in-situ polymerization. Microstructure, thermal properties, mechanical performance and tribological behaviors of these composites were investigated. The results indicate that nano-SiO 2 dispersed homogeneously. Compared with pure PI, thermal stability and heat resistance are higher about 10℃ with the addition of 5 wt% nano-SiO 2. Compressive strength and modulus of composite with 5 wt% nano-SiO 2 increase by 42.6 and 45.2%, respectively. The coefficient of friction (COF) of composite with 5 wt% nano-SiO 2 decrease by 6.8% owing to the thick and uniform transfer films. Excess nano-SiO 2 could adversely affect the COF of PI/nano-SiO 2 composite. Additionally, wear resistance deteriorates obviously since transfer film exfoliates easily and nano-SiO 2 aggregates on the surface of transfer films.

“…Recently, polymer-clay nanocomposites have attracted considerable interest from researchers due to their tremendous properties and broad applications [1][2][3][4][5]. By introducing a low clay content (usually 1-10 wt %) into a polymer matrix, these nanocomposites can achieve many unique properties, such as reduced thermal diffusion coefficients, increased barrier characteristics, high heat-distortion temperatures, decreased gas permeability and enhanced mechanical properties, compared with conventional composites or pure polymers [6][7][8][9].…”

Polystyrene-organo-montmorillonite (PS-OMMT) nanocomposite particles were prepared via emulsion polymerization of styrene in the presence of montmorillonite modified with an anionic surfactant, sodium lauryl sulfonate (SLS), and its tribological properties as an additive to polyalphaolefin (PAO) were tested. The results of Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA) showed that SLS molecules resided in the montmorillonite (MMT) interlayer space. The effects of OMMT on the morphology and properties of the nanocomposites were also investigated. Gel permeation chromatography (GPC) and dynamic light scattering (DLS) demonstrate that the presence of OMMT can effectively reduce the average molecular weight and average particle size of PS. XRD and transmission electron microscopy (TEM) of the PS-OMMT nanocomposites indicate that exfoliated and intercalated structures form and that the MMT layers either are partly embedded inside the PS particles or remain on their surface. Compared with pure PS, the PS-OMMT nanocomposites possessed higher stability to thermal decomposition and higher glass transition temperatures. Adding nanocomposite particles reduces the friction coefficient, and thus, the antiwear properties of the PAO are significantly improved. The PS-OMMT-3 (3 wt % of OMMT based on styrene) particles have the best tribological performance and maintained a stable, very low coefficient of friction of 0.09.
