“…Ghosh et al [127] studied the same composite and found that the friction coefficient decreased up to 10 vol%; the best wear performance was achieved from the samples with 5.0 vol% Ti 3 SiC 2 reinforced polyaryletherketone composites. Using low content 1.0 wt% Ti 3 SiC 2 , Xu et al [128] produced the polytetrafluoroethene-based nanocomposites with a wear rate of 125 times lower than the unreinforced samples. Besides the studies mentioned earlier being considering thermoplastic based composites, [126][127][128] some others have focused on thermoset based MXene nanocomposites.…”

MXenes are recently discovered 2D nanomaterial with superior mechanical, thermal, and tribological properties, being commonly employed in a wide variety of critical research areas, ranging from cancer therapy to energy and environmental applications. Due to their special properties, such as mechanoceramic nature with excellent mechanical performance, thermal stability and rich surface properties, MXenes have tremendous potential as advanced composite structures, especially those based on polymers due to a great affinity between macromolecules and the terminating groups of 2D MXenes. MXenes have been extensively explored in metal matrix nanocomposites as well as in solid‐ or liquid‐based lubrication systems owing to the 2D structure and antifriction characteristics. The purpose of the this paper is to provide a comprehensive insight into the material, mechanical, and tribological properties of the MXene nanolayers with discussions on the recent advancements attained from MXene‐reinforced nanocomposites starting with the synthesis, fabrication techniques, intricacies of the underlying physics and mechanisms, and finally focusing on the progress in computational studies. This analysis of MXene‐based composites will stimulate an emerging field with innumerable opportunities and ample potentials to produce newfangled materials and structures with targeted properties.

“…Based on the current seal application of PTFE, ideal sealing materials should have high thermal stability, low heat expansion coefficient, toughness, and a convenient preparation technique. Consequently, addition of inorganic filler into PTFE is a reasonable modification method, which can extremely improve the thermal expansion and creep resistance of the substrate . In addition, in order to obtain materials with high tenacity and porosity like ePTFE, several methods related to the fabrication of porous structure were investigated.…”

“…Consequently, addition of inorganic filler into PTFE is a reasonable modification method, which can extremely improve the thermal expansion and creep resistance of the substrate. [19][20][21] In addition, in order to obtain materials with high tenacity and porosity like ePTFE, several methods related to the fabrication of porous structure were investigated. Yin et al 22 prepared the polycaprolactone (PCL) porous membranes through mixed NaCl particles, polyethylene glycol (PEG), benzoyl peroxide (BPO), and polycaprolactone in dichloromethane (DCM) by ultrasonic dispersion, and then removed the DCM before press-molded at130 C. After cooling, membranes were soaked in ethanol and deionized water to completely leached out BPO, NaCl particles and PEG.…”

To achieve polymer‐matrix composites for sealing materials with thermostability and toughness, PTFE composites filled with short glass fibers (SGFs) were hyperthermal stretched to prepare a substrate material with high thermal stability and porosity. The effects of various tensile rates on the thermal and mechanical properties and morphologies were investigated. The results revealed that the thermal stability could be improved slightly and the thermal expansion coefficient of composites increased by the tensile rate. Through observing the morphologies, tensile process produced cavities and the increased tensile rate had negligible effects on porosity, which also could be proved by density test. From mechanical properties analysis, stretched composites exhibited that the tensile strength increases first and then decreases with the increased tensile rate. Although the variation tendency of Young's modulus is similar to that of tensile strength, which is smaller than that of unstretched composite. When the tensile rate reached 50 mm·min−1, the tensile strength and Young's modulus of the stretched composites increased by 65 and 9% to maximum, respectively. Meanwhile, elongation at break and shore hardness decreased. The thermal and mechanical properties improvement could be ascribed to the strain‐induced crystallization and crystal alignment. In addition, the interplanar spacing and grain size were inversely proportional to the tensile rate. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48175.

The filling combination of polytetrafluoroethylene (PTFE)/Cu/Al2O3 filled poly(methyl methacrylate) (PMMA) based composites aiming at low friction and wear is optimized based on L9(34) by Taguchi method. The worn morphologies of PMMA based composites are analyzed by scanning electron microscopy (SEM). The PTFE transfer film and the wear debris on the steel ball surface are analyzed by SEM and X‐ray spectroscopy. It is observed that the friction and wear of PMMA can be obviously decreased by filling with PTFE, Cu, and Al2O3. PTFE has the most significant but Cu has the negligibly smallest contribution on both the friction coefficient and the wear rate. The lower friction coefficient (<0.2) appears by the combination of the mass ratio of PTFE larger than about 4.5% and the mass ratio of Al2O3 lower than ∼7.5%. The lower wear rate (<5 × 10−5 mm3/Nm) appears by the combination of the mass ratio of PTFE larger than about 5% and the mass ratio of Al2O3 lower than ∼8%, but it does not include that PTFE is greater than about 8.5% and Al2O3 is less than about 1.5%. © 2018 Wiley Periodicals, Inc.
