<p>Wear and corrosion occurred on electrical contact pair are a major cause of equipment failure. The nanomaterials with high conductivity and low interface shear could be applied to improve electronically controlled friction. Based on the friction reduction of roll wood and nanosheets slip, graphene nanosheets (GNSs) coated with silver nanorod (SNR) composite were prepared via in situ reduction method. The experimental results show that the conductivity of 1-octyl-3-methylimidazole hexafluorophosphate (LP108) and its 0.05 wt% nanocomposite lubricant with the mass ratios of AgNO₃ to GNSs is 60: 1(LP108/0.05 wt% SNR-GNSs-60) that was increased by 5.4 times than that of the pure ionic. The average coefficient of friction (COF) of the LP108/0.05 wt% SNR-GNSs-60 was reduced to 0.0723 under condition without the current carrying, and its wear volume was decreased by 97.3% as compared with that of the pure LP108. This appearance was due to that the shear stress between the friction pair was largely reduced by SNR-GNSs additives. According to the principle of "rolling wood to transport stones," rolling, filling and self-repairing were carried out at the metal wear marks, leading to a lower friction and wear of friction pair. For the condition with the voltage of 1 A and the longer time of 1&#xa0;h, the COF of this lubricant was decreased to 0.0687 and the wear was reduced by about 90.2%. That is because the nanoparticles were formed electrochemical wear defects on the frictional interface. This work reveals that SNR-GNSs acted as the new lubricant additives could be applied in the field of electronic friction.</p>
