Electrically conductive polymers reinforced with carbon
nanotubes (CNTs) have generated a great deal of scientific and
industrial interest in the last few years. Advanced
thermoplastic composites made of three different weight
percentages (8%, 9%, and 10%) of multiwalled CNTs and polyether
ether ketone (PEEK) were prepared by shear mixing process. The
temperature- and pressure-dependent electrical resistance of
these CNT-PEEK composites have been studied and presented in
this paper. It has been found that electrical resistance
decreases significantly with the application of heat and
pressure. Keywords:Compression pressure; Carbon nanotubes;
Polyether ether ketone (PEEK); electrical resistance; tunneling
Electrical conductivity of thermoplastic composites containing
carbon nanotubes (CNTs) is due to the formation of a continuous
conductive network in the polymer matrix . This network consists
of specific spatial arrangement of conductive elements so that
low resistance electrical paths are developed for free m
