“…We have already argued about their capital influence on the thermal conductivity, but now is the time to focus on the mechanical behaviour [47][48][49]. Whereas the stress-strain relationships on the microscale have been found to be very similar to those of the bulk, remarkably high sub-micron yield strengths have been reported for different materials [47,[50][51][52].…”

Insects are recognized with their ability to efficiently move, operate, and function, and hence are inspiration for the design of micromechanical systems. This work deals with the structural, mechanical, and frictional characterization of the leg joint articulations of the katydid (Orthoptera: Tettigoniidae). For the katydids, the tibia joints were found to show a nanosmooth texture while the femur joint had a micro/nanotextured surface characteristics. The nanotexture was a two-tone periodic patterns with the hierarchical structures involving cylindrical ridges that are covered with nanoscale lamellar patterns perpendicular to the long axis and valleys between ridges that are decorated with the hillock patterns. The tibia and femur contact regions showed the reduced elastic modulus (Er) values ranging from 0.88 ± 0.01 GPa to 3.90 ± 0.11 GPa. The friction coefficient (μ) value of 0.053 ± 0.001 was recorded for the sliding contact of the tibia joint against the femur joint in air under dry conditions. The low friction values are attributed to the reduced real area of contact between the joint pair due to the coupling of the nanosmooth surfaces against the hierarchically nanotextured surfaces.

“…A new group of polymer nanocomposites based on integrating fullerene-like fillers into conventional polymer matrix has been developed in the last years. A review of these works is given by Maharaj and Bhushan [4]. Polymer nanocomposites containing fullerenes have great potential for versatile applications which include optical interrupters, polymer photoconductors, electrodes in lithium batteries, electro-optical structures in nano-electronics, nonlinear optics and photovoltaic devices [5,6].…”

Abstract:The effect of fulleroid materials (fullerene C 60 and fullerene soot which is used for fullerene production) and carbon fibers on the mechanical and tribological properties of polymer nanocomposites based on polyamide 6 (PA6) was investigated. Composites were synthesized by in situ polymerization and direct mixing in an extruder. It was found that addition of these fillers during in situ polymerization was more effective at improving the mechanical and tribological properties of the composites. The use of the nanoparticles was an effective way to decrease the friction coefficient of the polymer composites because the fillers were the same size as the segments of the surrounding polymer chains. The steady state coefficients of friction with the addition of fulleroid fillers were lower than that of unfilled PA6. The lowest coefficient of friction was observed for PA6 filled with 1 wt. % fullerene soot.
