Special Issue Information

Dear Colleagues,

High-performance polymers such as polyimides, polyaryetherlketones and sulfone polymers are replacing conventional materials used in aerospace and automotive applications, such as ceramics and metals, mainly due to their lightness, high heat and oxidative resistance, chemical inertness, high dimensional stability, corrosion resistance and ability to maintain mechanical and physical properties over a wide temperature range. In addition, these plastics can be easily moulded to thin-wall and complex geometrical components, offering design flexibility to satisfy continuous demand for component miniaturization, functional integration, safety and esthetical features that lead to their use in the automotive, electric and electronic applications. High-performance polymers are widely used in medical device applications due to combinations of good mechanical and chemical properties, their ability to tolerate various sterilization protocols and biocompatibility.

This Special Issue welcomes contributions to the preparation of high-performance polymer composites, characterization, testing and practical application. The article types include both research articles and reviews.

This paper addresses peculiarities in the formation and adherence of a tribofilm on the wear track surface of antifriction PI- and PEI-based composites, as well as a transfer film (TF) on a steel counterface. It is shown that during hot pressing, PTFE nanoparticles melted and coalesced into micron-sized porous inclusions. In the PEI matrix, their dimensions were much larger (up to 30 µm) compared to those in the PI matrix (up to 6 µm). The phenomenon eliminated their role as effective uniformly distributed nanofillers, and the content of 5 wt.% was not always sufficient for the formation of a tribofilm or a significant decrease in the WR values. At the loaded content, the role of MoS2 and graphite (Gr) microparticles was similar, although filling with MoS2 microparticles more successfully solved the problem of adhering to a PTFE-containing tribofilm in the point tribological contact. This differed under the linear tribological contact. The higher roughness of the steel counterpart, as well as the larger area of its sliding surface with the same PTFE content in the three-component PI- and PEI-based composites, did not allow for a strong adherence of either the stable PTFE-containing tribofilm on the wear track surface or the TF on the steel counterpart. For the PEI-based composites, the inability to shield the steel counterpart from the more reactive polymer matrix, especially under the conditions of PTFE deficiency, was accompanied by multiple increases in the WR values, which were several times greater than that of neat PEI.
