Low-density PE and FP as matrixes and MWCNTs and grinded EG as fillers were chosen for preparation of NCM samples for testing.A special vacuum mold with a spinner was used to make the samples by extruding the NCM molten mixture. Parameters of nanotubes were as follows: average diameter of 10-20 nm, specific surface area (determined by argon desorption method) of 200-400 m2/g, and poured bulk density varying from 20 to 40 g/dm3.Polyethylene and carbon nanotubes-based powder mixtures were mechanically milled in a drum mixer.Low-density PE is a moisture- and corrosion-resistant and price-accessible raw material.

Low-density PE and FP as matrixes and MWCNTs and grinded EG as fillers
were chosen for preparation of NCM samples for testing. Low-density PE is a
moisture- and corrosion-resistant and price-accessible raw material. Among all

types of polyethylene, this material has the highest physical and chemical perfor-
mance. MWCNT were purified in a traditional way in a solution of hydrofluoric

hydrochloric acid, after which they were washedobtained by the CVD method in a
rotating reactor [5, 6]. As a catalyst, oxides of the type Al2O3-MoO3-Fe2O3 were
used. The source of carbon was propylene, obtained by dehydration of isopropyl
alcohol. MWCNT were purified in a traditional way - in a solution of hydrofluoric
hydrochloric acid, after which they were washed. Parameters of nanotubes were as
follows: average diameter of 10–20 nm, specific surface area (determined by argon
desorption method) of 200–400 m2/g, and poured bulk density varying from 20
to 40 g/dm3. The concentration (C) of nanotubes in the NCM was changed in the
range of 0.3–5 vol.%. Polyethylene and carbon nanotubes-based powder mixtures
were mechanically milled in a drum mixer. A special vacuum mold with a spinner
was used to make the samples by extruding the NCM molten mixture.
