Geometry effect of different PTFE fillers on self-lubricating PF composites: Mechanical and tribological properties

open access: yesJournal of Materials Research and Technology
In order to further improve the performance of polytetrafluoroethylene (PTFE) as lubricant additives, PTFE fiber bundles (PTFE-F) were prepared by wet spinning to enhance phenolic resin (PF), and PTFE powders (PTFE-P) were used as a contrast phase.

Shear‐Induced Emergence of Aromatic Superlow‐Friction Interfaces in Amorphous Carbon: Triggering Chemical Impurities and Atomic‐Scale Mechanisms

open access: yesAdvanced Science, EarlyView.
High‐throughput quantum‐mechanical simulations reveal that amorphous carbon undergoes shear‐driven structural transformation into aromatic, graphene‐like interfaces. This mechanochemical process is governed by dopant chemistry: dopants with valency less than four promote the emergence of superlow‐friction amorphous graphene, whereas tetra‐valent ...

Synthetic of phenolic resin@SiO2 containing PAO6 to reinforce the tribological properties of PTFE/aramid fabric liner composites

open access: yesJournal of Materials Research and Technology
In this study, SiO2 containing PAO6 microcapsules were endowed with surface active groups by polydopamine (PSPMS). Then the modified microcapsules were in situ grafted into phenolic resin (PF@PSPMS) to control the dispersion and bonding in high viscosity

Experimental advances in superlubricity [PDF]

open access: yesFriction, 2014
Abstract Superlubricity, or structural lubricity, is a state that has two contacting surfaces exhibiting no resistance to sliding. This effect has been theoretically described to be possible between two completely clean single crystalline solid surfaces.
