“…Fullerene has been one of the most important carbonaceous nanomaterials of last 50 years because it possesses a unique zero-dimensional structure. Fullerenes and their derivatives have gained usage in polymeric composites with various applications, including photovoltaics, [1][2][3] voltage stabilizer, 4 nanosensors, 5,6 conductive materials, [7][8][9] and improvements of their tribological 10,11 and mechanical 12,13 properties. However, pristine fullerene particles tend to form aggregates in polymer matrices, which is the major problem that limits its proper applications.…”

Thermoplastic polyurethane (TPU) composites filled with fullerene in the range from 0.5 wt% to 2 wt% were fabricated using melt-compounding. Fullerene addition levels up to nearly twofold increase in tensile strength, percent elongation, and modulus of TPU. The mechanical properties are improved as modified C 60 content decreases. Fullerene loadings also enhance thermal stability of TPU. Glass transition temperature decreases by the inclusion of C 60 into TPU matrix. Composites exhibited the improvement for storage modulus and vibration-damping behavior. The UL-94 rating and limiting oxygen index value of TPU are also extended to higher values after C 60 loadings. Adjuvant effect is observed on fire performance in which pristine C 60 inclusions and higher concentrations of C 60 exhibit better fire performance. Additions of C 60 give identical melt flow index values with that of TPU. Modified C 60 particles disperse more homogeneously than pristine ones into TPU matrix because of the improvement in interfacial interactions between fullerene and polyurethane elastomer.

“…High performance polymer-based composites should bear eminent self-lubrication, superior heat resistance, excellent mechanical properties, and favorable chemical inertness. In general, engineering plastics served as polymeric matrixes were being extensively used for numerous mechanical and tribological purposes. − Most of all, known as semicrystalline thermoplastic polymer, polyphenylene sulfide (PPS) is a good tribo matrix and is widely utilized in the aerospace industry, military equipment, and automobile manufacturing, as a result of having high service temperatures, fairly low water absorption, fine creep resistance, quite high chemical stability, and high rigidity. , …”

Polyphenylene sulfide (PPS) based composites were prepared by hybridization between multiscale carbon fiber (CF) and polytetrafluoroethylene (PTFE) fiber, with, meanwhile, PPS serving as matrix, to obtain the interlocking network structure of CF–PTFE fiber hybridization. Dynamic rheological behavior distinctly illuminates the formation of the effective network structure situated inside the composites, which can effectively improve the tribological properties of the composites. Additionally, the PPS/PTFE/short carbon fiber (SCF) composites possess better friction and wear properties, compared with PPS/PTFE/micrometer carbon fiber (MCF) composites. More importantly, the PPS/PTFE/SCF20 composites are endowed with the lowest friction coefficient of about μ = 0.103, under the dry-sliding condition. Studying the transfer film and worn surface of composites, the results demonstrated that the wear mechanism gives priority to adhesive wear and accompanying abrasive wear; furthermore, tribochemical reaction occurs in the sliding process by energy dispersive X-ray spectroscopic (EDS) and X-ray photoelectron spectrscopic (XPS) analysis. The study of self-lubricating composites of multiscale CF–PTFE fiber hybridization has important application prospects in mechanical devices for the military, aerospace industry, and automotive industry.
