It was shown that not only concentration and structural, physical, and chemical characteristics of the filler but also the conditions for the production of samples are important for the creation of nanocomposite material based on PE and MWCNTs.The degree and time of structural relaxation of nanocomposite FP-EG depend on the size of the filler particles: with an increase in the size from 40 to 260 um, the relaxation rate reduces by 25%; with an increase in concentration from 1 to 5 vol.The addition of carbon nanotubes in 4-5 vol.% to the polyethylene matrix allows to obtain not only the conductive composite but also to increase the stiffness of the material.The conditions of creation effect on the structuring of the matrix, which leads to stabilizing its characteristics and controlling the damping parameters of the material.% the relaxation time increases almost twice.

The conditions of creation effect on the structuring of the matrix, which leads to stabilizing its characteristics and controlling the damping parameters of the material.
The addition of carbon nanotubes in 4–5 vol.% to the polyethylene matrix allows
to obtain not only the conductive composite but also to increase the stiffness of the
material.
The EG particles morphology and their distribution in the polymer matrix play
an important role in the nanocomposite effective properties. For NCM with a
fluoroplastic matrix and EG filler, the degree of crystallinity of the matrix increases
from 55 to 65.7% with an increase in the average particle size of the EG particles
from 40 to 260 μm. It also decreases with increasing concentration of the carbon
phase due to a change in the structurally active part of filler surface, where processes
of crystallization of phase transition occur.
The degree and time of structural relaxation of nanocomposite FP-EG depend
on the size of the filler particles: with an increase in the size from 40 to 260 μm,
the relaxation rate reduces by 25%; with an increase in concentration from 1 to 5
vol. % the relaxation time increases almost twice. Also, it was concluded that the
nanoparticle/polymer interphase region plays a significant role in the nanocomposite
properties and its creep behavior. Besides, the interphase effect is found to be more
significant on the MNC creep resistance with larger particles and their aggregations
as compared with that of NCM creep response with smaller ones.
