Capitalizing on wrapped MWCNTs and high-temperature lubricants produce a light weight and flexible poly(ether ether ketone) composite film with excellent thermal stability and mechanical property for wide-band electromagnetic interference shielding.

A comparative study on the influences of whisker and conventional carbon nanotubes on the electrical and thermal conductivity of polyether ether ketone composites

“…Notably, the SE of 10 wt% Wh‐CNTs was almost 1.13‐fold higher than that of 15 wt% carbon nanofiber loaded with polystyrene foam composite 54 . The SE of 9 wt% PEEK/wrapped MWCNT/GENIOPLAST® PELLET S (GPPS)1.0 with a thickness of 0.18 mm and that of 11.5 wt% GNP/carbonized loofah fiber (CLF)/PEEK with 1.0 mm was only 10.5 and 13.4 dB, respectively 55,56 . An exponential increase in SE (tested at 8.2 GHz) with decreasing logarithm of volume resistivity was observed (Figure S9).…”

A review of electrically conductive poly(ether ether ketone) materials

“…Lin et al 78 . and Na et al 18 . incorporated processing aids of poly(aryl ether ketone) (FPEDEKKLCP) (0–5 wt%) and granular GENIOPLAST® Pellet S (GPPS) to PEEK /CVD MWCNT (7 wt%) composite using a twin‐screw extruder to prepare electrically conductive composites.…”

“…It can be moulded by injection moulding and is used in nuclear plants, military, aerospace, chemical process equipment, oil‐well and bio applications 4–10 . PEEK has wide commercial application in electronic, telecommunication, healthcare and transportation industries (automotive, aeronautics and aerospace) and interest is continually growing in the ability to manufacture PEEK composites for electromagnetic interface (EMI) shielding and anti‐static applications to further enhance its applicability in these sectors 11–18 . Greater specific strength, more efficient, sustainable and cost effective mass production, higher corrosion resistance, and the absorption‐based mechanism of EMI shielding of PEEK materials has given rise to significant interest in PEEK as a replacement for metals from industries such as aerospace, weapons and microelectronics 19–23 .…”

Oxidized multiwall carbon nanotube/silicone foam composites with effective electromagnetic interference shielding and high gamma radiation stability

“…Traditional shielding materials are metals and alloys, which suffer from poor chemical resistance, heavy weights, poor exibility and difficulty in processing. 4 Recently, conductive polymer composites (CPCs) as EMI shielding materials have attracted broad attention due to their light weight, ease of fabrication, good stability and low cost. 5,6 Solution casting is a common dispersion technique for the preparation of CPC EMI shielding materials because of the well dispersion of conductive llers in polymer matrices and the prevention of damage to llers.…”
