Effect of grafted polytetrafluoroethylene nanoparticles on the mechanical and tribological performances of phenol resin

Preparation and tribological properties of graphene oxide/nano-MoS2 hybrid as multidimensional assembly used in the polyimide nanocomposites

“…The formation of the transfer lm greatly reduces direct contact and scraping between the counterpart and specimens, thereby effectively reducing the friction force. [60][61][62] A homogeneous transfer lm was also obtained in the case of GNF/PI composites, as reported. 31 The transfer lm formed by GNF/PI is smoother than that formed by GMS/PI and possesses a more outstanding effect in reducing abrasive wear.…”

Electrostatic and mechanical properties of extrusion spun PTFE monofilament with integration of microtourmaline particles

“…Figure presents the changes in ATR‐FTIR spectra as a function of proton irradiation time of PTFE before and after the addition of tourmaline particles. The major characteristic bands at 1205 cm −1 and 1148 cm −1 primarily correspond to CF 2 symmetrical and asymmetrical stretching in the PTFE, respectively . With the increasing content of tourmaline particles, the intensity of these characteristic bands decreased significantly.…”

Preparation and performance of tannin-glyoxal-urea resin-bonded grinding wheel loaded with SiO2 reinforcing particles

“…Grinding wheels are frequently used for processing materials in construction, interior decoration, mechanical manufacturing and other fields (Li et al 2020, Klocke et al 2015, Manoharan et al 2015. For three decades, phenol-formaldehyde (PF) resin has been widely employed as a binder for the preparation of abrasive materials (Robie 1957, Rowse and Stinchfield 1959, Wang et al 2011, Luo et al 2012. However, the release of free formaldehyde during preparation and use cause environmental pollution, limiting its industrial application.…”
