The modified single-walled carbon nanotubes (m-SWCNTs)/poly(ether ether ketone) (PEEK) composites were prepared by solution blending and melt blending, respectively. The mechanical, dielectric, and frictional performances of the m-SWCNTs/PEEK composites obtained by different processing technic were investigated. The poly(aryl ether ketone)s with pyrene (PAEK-Pys) were synthesized through iridium-catalyzed C−H borylation followed by Suzuki coupling. PAEK-Pys were characterized using ultraviolet–visible spectroscopy, proton nuclear magnetic resonance spectroscopy, and gel permeation chromatography. The polymers were then used for surface modification of pristine SWCNTs. Finally, the m-SWCNTs were used to prepare m-SWCNTs/PEEK composites via co-blending in solution or melt. The mechanical, frictional, and dielectric performance of the m-SWCNTs/PEEK composite by solution blending were better than these in m-SWCNTs/PEEK composite by melt blending. These results suggest that the method of solution blending is more favorable for the dispersion of the SWCNTs in PEEK.

The wear behaviour of poly (ether-ether-ketone) (PEEK) composite was investigated according to the load and test speed. Three types of materials were studied: first, neat PEEK, PEEK with 30 wt. % carbon fiber (PEEK CF30), and third, PEEK with carbon nanotubes (PEEK ELS NANO). Tribological tests were performed on the universal tribometer UMT-2, using a pin-on-disc device. The friction coefficient and wear rate for the composites studied were analysed. Tests carried out have allowed the examination of the influence of load and speed on the friction coefficient and wear rate under dry sliding regime. Also, structural changes were noticed by optical and SE microscopy, and wear types of surface were discussed. As a result of experimental tests, it was established that PEEK composite with carbon fiber/carbon nanotubes exhibit good wear behaviour under operating conditions.
