“…Meanwhile, the wear rate increases steadily during the speed from 15.7 to 39.3 m/s, and then increases sharply when the speed rises to 47.1 m/s like PF (shows in Figure 2 b). This phenomenon is consistent with that of some relevant and recent reported papers, in which the friction coefficient and wear rate decreased with the increasing Gr content below 10 vol.% [ 46 , 47 , 48 ]. The specimen 20Gr has the same friction coefficient of 0.35 from the speed of 7.9 to 15.7 m/s.…”

In this paper, the influence of graphite (Gr) on the dry sliding tribological properties of phenolic resin (PF) composites was studied under different sliding speeds of 3.1–47.1 m/s. The wear mechanism was investigated by the observation of the morphology of the transfer layer during the dry sliding process. It was found that the addition of Gr could decrease the friction coefficient and wear rate effectively, and the friction coefficient and wear rate decreased with the increase of Gr content in the range of 10–30 vol.%. The dominant wear mechanisms of PF-based friction composites changed from adhesive wear to fatigue wear (in the form of peeling-off) in the high sliding speed condition after the addition of Gr. The addition of Gr effectively reduced the sensitivity of PF-based friction materials to sliding speeds, and thus enhanced the stability of the friction coefficient. When the content of Gr was above 20 vol.%, the stability of the friction coefficient was relatively steady.

“…This was the result of the stress transfer improving with higher aspect ratio of exfoliated GNP. [40][41][42][43][44] In addition, the nanoscale fillers restricted the polymer chain mobility at the interface, increasing the stiffness of the composites. 45 The composites pretreated by the mixed ) was larger than that of PP/Py-PP/GNP(10/0), which means the improvement of the resistance to thermal degradation.…”

To improve the dispersion of graphene nanoplatelet (GNP) in polypropylene (PP), GNP was exfoliated in a mixed solvent of p-xylene and N,N-dimethylformamide (DMF) and the exfoliation of GNP was maintained by the addition of a compatibilizer before the melt blending. The concentration of the dispersed GNP in various ratios of the mixed solvents was measured in order to confirm the effect of the mixed solvent on the pre-treatment process. As a compatibilizer for the composite, pyrene-functionalized maleic anhydride-grafted polypropylene (Py-PP) was synthesized. The dispersion state of the composites was analyzed by the three dimensional non-destructive X-ray micro-computed tomography (3D micro-CT). The improved dispersion of GNP resulted in a significant enhancement in the mechanical properties. Young's modulus of PP composites with 2 wt% GNP has increased by 43% compared with that of PP. These results are attributed not only to the improved interfacial interaction between PP and GNP, but also to the homogeneous dispersion state of the GNP in the matrix.

“…Because of the asymmetry of the peak at a low binding energy, another bimodal is used to clearly present the W4f peak. It means that tungsten trioxide is deficient in oxygen, which supports the electronic transport properties of the material by the introduction of donor electrons [18][19][20][21][22][23] .…”

WO 3 nanorods were synthesized via a simple hydrothermal approach. Their microstructure and morphology were analyzed with x-ray diffraction, scanning electron microscope and x-ray photoelectron spectroscopy. The effects of reaction temperature, reaction time, and citric acid concentration, on the gas-sensing performance of WO 3 nanorods were investigated. The optimized response value of WO 3 sensor to ethanol gas (100 ppm) was 26.48, with a response time of 1 s under a low operating temperature (160 °C). The recovery capability and stability of the gas sensor were tested and discussed. Additionally, the working principle of WO 3 sensor was proposed. In comparison to the sensors published by previous researchers, the WO 3 sensor has shown great potential.
