Embodiment 1
[0025] 10 g of polyaniline was weighed and added to 50 g of 1-butyl 3-methylimidazolium hexafluorophosphate, the mixture was heated to 80° C. and stirred for 1 hour, and then the mixture was cooled to room temperature. Add acetone to dilute and filter for 3 times, then put the filter cake in an oven and dry at 40°C for 24 hours to obtain 1-butyl 3-methylimidazolium hexafluorophosphate modified polyaniline powder.
[0026] Weigh 3g of the modified polyaniline powder prepared in the above steps, add it to 50g of synthetic oil, heat the mixture to 80°C and stir for 2 hours to fully disperse the polyaniline in the synthetic oil, then add 20g of polytetrafluoroethylene , continue stirring at 80° C. for 2 hours, wait for the mixture to cool to room temperature, and use a grinder to grind three times to obtain polyaniline grease.
Embodiment 2
[0028] 15 g of polyaniline was weighed and added to 60 g of 1-butyl 3-methylimidazolium tetrafluoroborate, the mixture was heated to 60° C. and stirred for 1 hour, and then the mixture was cooled to room temperature. Add petroleum ether to dilute and filter 5 times, and then put the filter cake in an oven at 50° C. for 24 hours to obtain 1-butyl 3-methylimidazolium tetrafluoroborate-modified polyaniline powder.
[0029] Weigh 5 g of the modified polyaniline powder prepared in the above steps, add it to 80 g of mineral oil, heat the mixture to 100° C. and stir for 2 hours to fully disperse the polyaniline in the mineral oil, then add 20 g of bentonite, at 80 Stirring was continued for 2 hours at °C, and the mixture was cooled to room temperature, and ground three times with a grinder to obtain polyaniline grease.
Embodiment 3
[0031] 6g of polyaniline was weighed and added to 50g of 1-hexyl 3-methylimidazolium hexafluorophosphate, the mixture was heated to 80°C and stirred for 1.5 hours, and then the mixture was cooled to room temperature. Add absolute ethanol to dilute and filter 3 times, then put the filter cake in an oven and dry at 60°C for 24 hours to obtain 1-hexyl 3-methylimidazolium hexafluorophosphate modified polyaniline powder.
[0032] Weigh 30g of synthetic oil and 30g of mineral oil and mix them thoroughly, weigh 6g of modified polyaniline powder prepared in the above steps, add it to the prepared mixed oil, heat the mixture to 80°C and stir for 1.5 hours, Fully disperse the polyaniline in the mixed oil, then add 8 g of attapulgite, continue stirring at 100° C. for 1.5 hours, wait until the mixture is cooled to room temperature, and use a grinder to grind three times to obtain polyaniline grease.
