Abstract—Copper nanoparticles in the matrix of ethylene propylene copolymer were derived by a method of
a high thermal decomposition of an organometallic precursor in a high shear. It was revealed that the decomposi-
tion temperature of the precursor increases signiﬁ cantly in the formation of nanoparticles in the polymer matrix.
It was found by X-ray diffraction analysis and scanning electron microscopy that copper nanoparticles in shape
close to spherical and of a wide particle size distribution are formed in the decomposition of copper formate di-
hydrate in an elastomeric matrix.
diene rubber SKETP-40 containing dicyclopentadiene
(TC 2294-022-05766801-2002) as diene copolymer.
Thermal analysis was performed on a DSC Netzsch
Phoenix 204 F1 with the cooling system Intracooler in
argon (an argon ﬂ ow 30 mL min
) at temperatures up to
200°C at a heating rate of 1 K min
The study of the modiﬁ ed samples was carried out
using X-ray analysis. Recording of diffraction patterns
was carried out on a DRON-3.0 unit in the radiation Cu
(Ni-ﬁ lter). The phase identiﬁ cation was carried out ac-
cording to the data of the interlayer distance calculated
from the Wolf–Bragg equation with ASTM ﬁ ling.
The analysis of the copper-containing samples was
also performed by electron microprobe analysis in
a scanning electron microscope Versa 3D DualBeam
(FEI Company, USA) at an accelerating voltage of 30 kV.
Determination of the particles size and investigation
of their structure were produced by a scanning electron
microscope Versa 3D DualBeam in low vacuum mode.
Samples containing copper nanoparticles in the
bulk of SKETP-40 were produced by the rapid thermal
decomposition of the precursor at high shear strains of
the rubber by two stages . In the ﬁ rst stage at room
temperature a binary mixture of ethylene propylene
The use of metal nanoparticles in the polymer allows
producing entirely new materials with a range of unusual
physical and mechanical properties. Such materials are
widely used in radio and optoelectronics as magnetic,
conductive, and optical environments [1–3, 7]. In addi-
tion, metal nanoparticles can improve the technological,
thermal, and other properties of the polymer composi-
A modiﬁ cation of the elastomer matrices by metal
nanoparticles of variable valence (copper, cobalt, nickel,
and others) can be one of promising ways to increase the
adhesion characteristics of the rubber.
The purpose was production of new composite
materials based on elastomers containing nano-scale
particles of copper, and investigation of their structure
The copper particles were used as test samples, which
was synthesized by high-rate thermal decomposition of
metal-containing compound (precursor), copper formate
