1. Introduction
It is impossible to imagine modern development of
science without polymers in all their diversity. In recent
decades, these materials became of great interest for
scientists in the frame of creation of highly selective
sensitive layers for sensors that are required in industry,
medicine, perfumery, environmental monitoring, food
control, etc.
Among sensors based on organic materials,
conductive polymers are the most common [1-10]. The
advantages of these sensors are above all an opportunity
to work at room temperature, easiness of manufacturing
and low cost.
Despite the large amount of works in this area, this
direction continues to be developed, as evidenced by a
large number of articles on this subject, which appear
every year.
It was shown [1] that Pd-polyaniline films are
highly sensitive and selective to methanol vapors and
provide stable signal for a long time. Polyaniline
ultrathin layers were prepared using the Langmuir–
Blodgett method, and gas sensitivity of these films to
NO was studied [2]. Using the Langmuir–Blodgett
methods, thin layers of pure polycarbazole and
polycarbazole mixed with octadecylamine were
obtained. The sensitivity of these ultrathin films to
ammonia was investigated by measuring changes in their
electrical resistance. It was found that the Langmuir–
Blodgett film with pure polycarbazole has higher
sensitivity and a faster response as well as recovery to
ammonia than the layers of mixed type [3]. In the work
[4], the polypyrrole layers that show high sensitivity to
ammonia were investigated. Composite polypyrrole-
poly(vinyl alcohol) layers were prepared using the
electrochemical method and were studied at various
concentrations in vapors of ethanol [5]. Nanocomposite
of copper/polyaniline was used as a sensor for
chloroform. The authors believe that sensitive
mechanism mainly includes adsorption-desorption of
chloroform on a metal surface of clusters [6]. The
polymer sensors were placed into vapors of different
gases: o-xylene, n-butane, benzene, methanol, n-heptane,
and 3-pentanone. Each sensor was subjected to repeated

exposure in these vapors at various concentrations.
Analysis of the obtained data has shown that the
sensitivity depends on the chemical nature of both the
sensor and studied vapors as well as duration of
exposure in vapors [7].
In this paper, we consider the adsorption properties
of thermally deposited polyvinylcarbazole (PVC) films.
2. Experimental procedure
In general, today we know quite a number of methods
for forming thin film coatings in a wide range of
thicknesses – from a few nanometers to hundreds of
micrometers. It is interesting to note that along with
traditional chemical methods of creating the coatings in
the form of thin films, classic methods of
microelectronic technology (namely, thermal
evaporation in vacuum with subsequent condensation on
the respective substrates) are widely used to obtain
stable coatings with desired physical and chemical
parameters. Polymer (polyvinylcarbazole (from
Aldrich)) films were deposited using thermal
evaporation in vacuum directly on the electrode of
quartz crystal microbalance (QCM).
The QCM sensor operation principle is
measurement of variation of the resonant oscillation
frequency of a piezoelectric crystal caused by change of
its mass due to analyte molecules adsorption onto the
sensitive layer surface. The responses of a QCM without
sensitive coating to all analytes under investigation did
not exceed 10 Hz [11, 12].
Our measurements with the QCM technique were
made as follows. The sensors were placed in a
measuring flow-type cell and were held in argon flow
until stabilization of the quartz resonators frequency
(deviation of ±1 Hz). Then analyte vapor in argon passed
through the cell with a constant flow-rate of about
60 ml/min. The analytes were ethanol, methanol and
perfume (Ukraine). The concentrations of analytes were
close to the saturation level.
The experiments were performed in a thermostatic
chamber where the sensor array and studied samples are
located [13]. The temperature in the experiment was
kept as 23 and 33°C.

3. Results and discussion
In this paper, polymer layers of PVC were prepared using
the method of vacuum deposition of films. Using the
unique chemical and physical properties of this polymer,
we studied the influence of vapors of different nature on
the surface of QCM with sensitive polymer layer.
Characteristics of gas sensors are defined by physical and
chemical properties of their sensor elements that, in its
turn, depend on the crystal structure, composition and
adsorption properties of the sensitive layers in the sensor
array. Changing the temperature during experiments, we
changed the adsorption properties of the sensor surfaces.
The analysis of sensor responses allows to estimate
kinetic curves for all the types of samples. At room
temperature, ethanol shows monotonic curves during the
whole experiment, methanol – first shows a small
plateau that goes also down to the monotonic curves.
Fig. 1 shows the influence of temperature on polymer
layers when adsorbing alcohol and methanol. As seen
from the results obtained, the increase in the temperature
by ten degrees (33 °C) leads to change of the form of the
response curves when adsorbing ethanol – the sensitivity
of polymer layers of quartz crystal and kinetic behavior
of the curves are changed. When temperature increases
from 23 to 33 °C much higher response on both ethanol
and methanol is observed (2.5…5 times).
For experimental researches, we also selected a more
complex analyte – Eau de Cologne – a multicomponent
mixture containing water-alcohol solution, essential oils,
terpenes, alcohols, aldehydes, ketones, menthol, camphor,
acetic acid. The evaporation temperatures of different
components in this mixture differ and this fact affects the
sensor response character. As seen from the figure, with
increasing the temperature to 33 °C, a dramatic change in
the kinetic of curves takes place when adsorbing cologne.
The determined properties of thermally deposited
films of PVC polymer, namely, changing the sensitivity
to vapors of alcohol and perfume when changing the
temperature, cause considerable interest to this material
in terms of its use in arrays of sensors to create devices
of the “electronic nose” type.
4. Conclusions
Thus, these results indicate that the structures based on
quartz/silver/polymer (QSM) can be used in sensor
arrays for the analysis of multi-component mixtures
based on alcohol, which is important for the chemical
and pharmaceutical industry, for production of alcoholic
beverages and to environmental monitoring. The
temperature can serve as an additional factor affecting
the functionality of these sensors.
