Abstract—The structure and properties of nanocomposites based on zinc sulﬁ de and poly(vinylidene ﬂ uoride)
were studied. The nanocomposite material was prepared by the matrix isolation technique: ZnS nanoparticles are
formed by chemical reactions in a poly(vinylidene ﬂ uoride) powder of particle size 0.5–1.0 μm.
Preparation of nanocomposites and study of their
properties are topical problems attracting increased
researchers’ attention. Interest in nanomaterials is due
to the following facts: With a decrease in the particle
size, the role of the surface energy increases, and the
thermodynamic conditions of phase equilibria change.
A decrease in the nanoparticle size shifts the phonon
spectrum toward shorter wavelengths. Therefore,
materials containing nanoparticles exhibit unique
physicochemical properties .
Today there is increased interest in preparation of
semiconductor nanoparticles in a polymeric matrix.
Polymeric nanocomposites containing particles of
a metal or a semiconductor are a promising class of
hybrid materials. Combination of unique magnetic,
catalytic, optical, sensor, and other properties of
inorganic nanoparticles with the set of properties of
the matrix opens wide possibilities for designing new
Semiconductor nanomaterials are prepared by
a number of methods such as sol–gel process ,
Langmuir–Blodgett method , molecular-beam
epitaxy , and multicycle treatment method .
Elucidation of the relationship between the character
of supramolecular formations and the properties of
polymers allow purposeful control of the structure of the
material being formed with the aim to attain the required
set of properties. Study of the structure of such materials
allows prediction of their properties, and from changes
in properties it is possible to judge the structure of the
In this study we examined the structure and properties
of composite nanomaterials based on poly(vinylidene
ﬂ uoride) (PVDF) matrix and zinc sulﬁ de nanoparticles.
To prepare the nanocomposite material, we used
the matrix isolation technique: ZnS nanoparticles
were formed by chemical reactions in a polymeric
matrix. The advantage of this method is that particles
are incorporated in the bulk of the polymeric matrix
directly in statu nascendi, which makes the process
relatively simple. As a matrix we used PVDF powder
with a particle size of 0.5–1.0 μm. This material is
a fairly convenient matrix owing to strength, sensitivity
to irradiation, and physiological harmlessness.
To enhance the activity toward metal ions, PVDF
powder was preliminarily γ-irradiated to doses of 20, 50,
and 100 kGy. To prepare PVDF + ZnS nanocomposite,
we ﬁ rst added to a deﬁ nite amount of PVDF powder
50 ml of a 0.1 M ZnSO
solution. The resulting mixture
was stirred with a power-driven stirrer for 30 min at
room temperature, after which the powder was ﬁ ltered
off and dried for 24 h. Then to the resulting dry powder
we added 50 ml of a 0.1 M Na
S solution. The resulting
