“…In recent years, there have been some efforts to overcome the limitations of PVDF. Worldwide scholars have improved the tribological properties of PVDF-based composites by adding a variety of llers, including carbon nanorods [25], TiO 2 nanospheres [26], MgO nanosheets [27], nano CeO 2 oil-containing diatomite [28], SnO 2 nanotubes [29], polyamide 66 [30] and nano clay [31]. All of the llers mentioned above are solid llers, and they can signi cantly improve the tribological properties of PVDF.…”

In the study, the waste polyvinylidene fluoride (PVDF) membranes were recovered and the micropowders of this polymer were obtained by solvent recovery method. Moreover, the new direction for applying waste PVDF membranes to the field of tribology were developed. Thus, a novel PVDF-based tribological composite (PAO@PSF/PVDF) was fabricated with recycled PVDF micropowders acted as the matrix polymer and PAO@PSF microcapsules with the configuration of polysulfone (PSF) capsuling lubricant oil (PAO) served as the filler. The self-lubricating and wear properties of PAO@PSF/PVDF composite were tested under dry sliding condition using a ball-on-disc configuration. In particular, this kind of composite with the inclusion of 20 wt% PAO@PSF microcapsules exhibited the best tribological properties, i.e., the lowest friction coefficient (0.077) and the smallest wear rate (2.34×10-15 m3/Nm). The filling of PAO@PSF microcapsules greatly improved the antifriction and wear resistance of PVDF, guaranteeing the self-lubricating feature of this polymer. The tribological properties of PAO@PSF/PVDF composite can reach close to those under the condition of dripping lubricating oil, and the prepared PAO@PSF/PVDF self-lubricating composite can be applied to a large range of friction conditions. Furthermore, without any doubt, it will facilitate the reutilization of waste polymers.

“…[ 10 ] Among the fillers, micro/nano particles always showed high efficiency for getting better friction and wear properties, due to the excellent transfer film on mating surface and the destruction prevent of the banded structure of PTFE. [ 16,17 ] However, scholars have focused on studying the tribological performance of PTFE composites rather than its compressive creep property, which is important for avoiding the leak of mechanical seals.…”

In order to improving the reliability and service life of polytetrafluoroethylene (PTFE) composites. Micro nickel-titanium shape memory alloy (NiTi) particles were incorporated with PTFE powder to develop the PTFE composites by using filling modification technology. Herein, 25 kinds of PTFE composites with different contents of micro NiTi particles were prepared, of which the tribological and compressive creep properties were investigated in detail considering the factors such as the NiTi content (0,10,20, 30, 40, and 50 wt%),20, 30, 40, and 50 MPa), and tested conditions(10 N, 10 Hz, 6 mm, 20 min). The filled different contents of NiTi particles could

In the study, the waste polyvinylidene fluoride (PVDF) membranes were recovered and the obtained resin powders by a solvent recovery method were employed for the fabrication of a novel PVDF-based tribological composite.Herein, a new strategy was developed for applying the waste PVDF membranes to fabricate a self-lubricant composite, where the recycled PVDF powders acted as the polymer matrix and microcapsules with the configuration of polysulfone (PSF) capsuling lubricant oil (PAO) served as the filler. The morphologies, crystal phases, chemical components and groups as well as thermal stabilities of fabricated PAO@PSF/PVDF composites were characterized, and the self-lubricating and wear properties of fabricated composites were tested under the dry sliding condition using a ball-on-disc configuration. Experimental results suggest that the PAO@PSF/PVDF composite with an addition of 20 wt% PAO@PSF microcapsules exhibits the best tribological properties, in view of the lowest friction coefficient (0.077) and the smallest wear rate (2.34 Â 10 À15 m 3 /Nm). The incorporation of PAO@PSF microcapsules greatly reduces the friction coefficient of PVDF polymer. The tribological properties of fabricated PAO@PSF/PVDF composite will be expectable to that of the PVDF polymer with the dripping presence of lubricating oil.
