Evaluating the triboelectric performance of trimethylolpropane trioleate grease
The study compared the triboelectric performance of trimethylolpropane trioleate (TMPO) grease with perfluoropolyether (PFPE) grease, both formulated with polytetrafluoroethylene (PTFE) as a thickener. Thermogravimetric analysis (TGA) revealed that TMPO grease exhibits 8.8% better thermal stabi...

| Summary: | The study compared the triboelectric performance of
trimethylolpropane trioleate (TMPO) grease with
perfluoropolyether (PFPE) grease, both formulated with
polytetrafluoroethylene (PTFE) as a thickener.
Thermogravimetric analysis (TGA) revealed that TMPO
grease exhibits 8.8% better thermal stability than PFPE
grease. TMPO grease shows a 22.1% improvement in
friction over PFPE without electricity. Under a 2 A current
flow, both greases show reduced frictional performance,
though the TMPO grease maintains a 9.8% lower friction
compared to PFPE. The better friction performance of
TMPO is attributed to its conductivity compared to PFPE,
despite both greases utilizing a non-conductive PTFE
thickener. |
