“…The results have been quite interesting but, at the end it has been seen that such fillers compromise PTFE's attractive low friction properties (μ<0.1) even if wear of said composites in comparison with virgin PTFE is further reduced [2]. Furthermore, the disadvantage of using hard phases in soft matrix is well known, that is, the possibility of transfer film removal and the aggressive abrasion of the hard counterface if the hard phases are released to the interface as a third body due to loosening of the bond between the filler and the polymer matrix: it was found that the particles used as fillers were rubbed off during the test, highlighting the weakness between the transfer film and the countersurface [3].…”

Tribological behavior of PTFE is highly affected by fillers used to improve its mechanical characteristics and depends on the ability of the material to maintain its integrity in the working conditions. Specifically, in the case under study, the heat generated by friction was modelled as a heat flow coming from a source at the contact surface in static condition. Considering that a heat flow is also supplied to the samples during a Differential Scanning Calorimetry (DSC) analysis, where crystallinity of material is evaluated, a correlation between thermal characteristics of the material, its structure and tribological behavior is presented.

“…With the increase of the Al ions implantation dose, nano composite films were more uniform and more consistent performance in the same ions and energy, and modification effect of PTFE was the best at implantation dose of 1×10 16 ions/cm 3 . The best metal ion was Al, implantation dose was 1×10 16 ions/cm 3 , implantation energy was 20Kev by SRIM optimization.…”

ABSTRACT:The effects of different solid substrates, including carbon nanofibers (CNFs), activated carbon, alumina, silica, molecular sieves, and poly(N-vinylpyrrolidione) (PVP), were compared for the high-pressure synthesis of polytetrafluoroethylene [PTFE or (CF 2 ) n ] nanoparticles via the adsorption of thermally synthesized tetrafluoroethylene (C 2 F 4 ) as the monomer. Scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis (TGA) were used for the characterization of the PTFE nanoparticles on different solid substrates. The results demonstrate that the average diameters of the PTFE nanoparticles were about 90 nm for the CNFs, 130 nm for PVP, 150 nm for alumina, and about 200 nm for silica. Also, TGA showed that the amounts of PTFE nanoparticles synthesized on each solid substrate were 3.53 6 0.09% for CNFs, 2.31 6 0.10% for PVP, 2.11 6 0.12% for silica, and 0.97 6 0.16% for alumina. Depending on the active surface area and the morphology of nanomaterials, such as CNFs, different capacities were evaluated for each solid support in the formation of the PTFE nanoparticles. The quantities and the size of the synthesized PTFE nanoparticles relied on the characteristics of the solid substrate.
