Abstract Carbon fibre/fabric (CF) is a privileged reinforcement for advanced polymer composites in tribological applications where performance is primary criteria rather than the cost due to the combination of distinct properties such as high specific strength, thermo-oxidative resistance, thermal and electrical conductivity along with self-lubricity etc. However problems associated with its ch...

in the past 30 years, electroless nickel (en) plating has grown to such proportions that these coatingsand their applications are now found underground, in outer space, and in a myriad of areas inbetween. moreover, in order to further improve the mechanical and tribological properties of thenickel-phosphorous (ni-p) coatings, ni-p/ptfe composite coatings can be obtained, which provideseven grea...

Eight titanium complex greases (i.e., benzoic acid/stearic acid and sebacic acid/stearic acid titanium complex greases, and greases containing PTFE, or nanotitanium dioxide, or nano-silicon dioxide) were synthesized using 3-L reaction vessel. Their physical characteristics were characterized and their tribological properties were evaluated by using a four-ball tester. Chemical compositions of t...

Abstract Polytetrafluoroethylene (PTFE) polymer is used extensively in industry as a solid lubricant because of its lack reactivity with most industrial materials. However, PTFE has low abrasive resistance, limiting application. In this study, the mechanical and tribological characteristics PTFE-based composites addition clay nano-sheets (CNSs) were investigated. Clay nano-sheet-PTFE (CNSTCs) c...

Polytetrafluoroethylene (PTFE) is a polymeric material with excellent self-lubricating properties. In this study, in order to improve the wear resistance of PTFE, PTFE matrix was filled soft-phase polyetheretherketone (PEEK) particles and hard-phase nano-ZrO2 varying volume ratios. A linear reciprocating friction tester used test tribological properties composites. Optical microscopy (OM) scann...

In this study, superhydrophobic ZnO/Polytetrafluoroethylene (ZnO/PTFE) films with water droplet contact angles (CA) observed as high 165° and sliding of (SA) <1° have been prepared on glass substrates by RF magnetron sputtering. The PTFE was wrapped a nano-rod made ZnO film properties while providing excellent UV resistance compared to hexadecyltrimethoxysilane (HDTMS) hydrophobic agents. up...

Metal particle size and environment will affect the reaction properties of aluminized polytetrafluoroethylene (Al/PTFE) reactive material. This study experimentally investigated Al/PTFE with different Al sizes through time-resolved self-emitting imaging emission spectroscopy under nanosecond laser ablation in air an inert argon environment. The results show that causes a continuous combustion c...

The motivation of this work is to create luminescent rare earth/polymer films with outstanding water-resistance and superhydrophobicity. Specifically, the emulsion polymerization of styrene leads to core particles. Then core-shell-structured polymer nanoparticles are synthesized by copolymerization of styrene and acrylic acid on the core surface. The coordination reaction between carboxylic gro...

Effect of Nanofiller Shape on Effective Thermal Conductivity of Fluoropolymer Composites Report Title Filler particle size and shape influence interconnectivity within a polymer matrix and play a significant role in controlling the effective thermal conductivity of a composite. This study examines the effect of nanofiller particle shape in a polytetrafluorethylene (PTFE) matrix on thermal energ...
