“…Hence, the tremendous amounts of research explorations were carried out to strengthen the anti-friction and wear resistance of PES polymer. Multifarious reinforcement materials consisting of aramid fibre [6], polytetrafluoroethylene [7], glass fibre [8], rare earths [9], carbon nanotube [10], short carbon fibre [11], expanded graphite [12] and MoS 2 [13] are introduced into the PES matrix via a myriad of preparation methods to enhance its mechanical, thermal and tribological performances.…”

Graphene oxide (GO) nanoplatelets were functionalised using sulphonated polyethersulphone (PES-SO 3 H) and subsequently as nanofiller incorporated into the PES matrix to improve its comprehensive performances. Influences of GO/PES-SO 3 H nanoplatelets on the surface wettability, nanomechanical property and tribological behaviours of GO/PES-SO 3 H/PES composite under various relative humidity were investigated. Test results indicate that the introduction of GO/PES-SO 3 H dramatically decreases the water contact angles and increases the nanoindentation hardness of PES. The effects of relative humidity on the friction coefficients of GO/PES-SO 3 H/PES composites are far less than that on the wear rates of PES composites. Compared with the pristine PES, the PES-matrix composite containing 1.0 wt-% GO/PES-SO 3 H nanoplatelets exhibits the minimum friction coefficient (0.11) and wear rate (5.83×10−14 m 3 /N m) under the high relative humidity of 90%. This is attributable to the reinforcement effect and hydrogen bonding interaction of GO/PES-SO 3 H nanoplatelets as well as the uniform and ultrathin PES self-lubricating transfer films.

“…In comparison with the specific wear rate of the pure PES ( K = 1.18 × 10 −12 m 3 /Nm), K of PES composite with GO addition of 0.6 wt% ( K = 1.07 × 10 −14 m 3 /Nm) decreases by a factor of 110. In addition, compared with the wear rates of carbon fiber/PES composite, aramid fiber/PES composite, polytetrafluoroethylene/PES composite, and MoS 2 /PES composite , the GO/PES composite shows the outstanding wear resistance in consideration of the low value of K under drying sliding conditions. Consequently, the friction‐reducing and anti‐wear properties of PES composites are greatly enhanced owing to the incorporation of GO.…”

Nano-sized graphite oxide (GO) sheets prepared from expanded graphite (EG) particles were incorporated into polyethersulfone (PES) to improve the friction and wear properties of this polymer. The influence of GO addition on the mechanical, thermal, and tribological performances of PES composites was evaluated. The results of Fourier transform infrared spectroscopy and scanning electron microscopy for GO/PES composites reveal that the hydrogen bonding interaction between GO sheets and PES matrix is formed. The mechanical and thermal properties of PES composites are obviously enhanced due to the incorporation of GO sheets. The friction reducing and anti-wear properties of GO/ PES composites are much better than those of the pure PES. Among these fabricated GO/PES composites, the PES composite reinforced with GO addition of 0.6 wt% exhibits the lowest friction coefficient (0.17) and specific wear rate (1.07 3 10 214 m 3 /Nm). This can be attributed to the homogeneous dispersion of GO sheets within PES matrix and the strong interfacial interaction between them, as well as the existence of uniform PES transfer film on the frictional interface.

Microwave-assisted acid decomposition and oil-in-water emulsification were evaluated as sample pretreatment procedures to determine Al, Ba, Mo, Si and V in lubricating oils by high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS). Average recoveries of Al, Ba and V in oil digests (107, 103 and 101%) were close to those obtained for emulsions prepared in kerosene medium (94, 113 and 95%). Average recoveries for Mo were close to 105 and 46% for emulsions and digests, respectively. Improved average recoveries (101%) were obtained for Mo in digests using the analyte addition technique. Silicon was successfully quantified only in digested samples. Limits of quantification for Al, Ba, Mo and V were 1.4, 31.5, 1.5 and 11.4-fold lower than those obtained by line-source FAAS. Enhanced sensitivity, multi-elemental capability, and high sample throughput are among the main advantages of HR-CS FAAS in comparison with the line-source FAAS technique.
