abstract = {Nanoparticles in combination with liquid crystals
facilitate the design of nanocomposite materials with unique
photoelectric or nonlinear optical characteristics. This
makes such materials multifunctional and adjustable for a
wide range of applications, including sensors to optical
devices.A promising matrix for the development of
nanocomposite materials is the thermotropic ionic smectic A
Cd+2(C7H15COO-)2 (CdC8) liquid crystal (LC). This LC can
perform nanoreactor functions for synthesizing different
types of nanoparticles: semiconductor, metal, metal alloys
and hybrid nanoparticles (core/shell). The shape and size of
nanoparticles in our synthesized composite materials are
measured using scanning electron microscopy and transmission
electron microscopy. These methods allow us to obtain
high-resolution images and precisely study the distribution
and characteristic sizes of the nanoparticles in the CdC8
matrix. The samples are measured using impedance
spectroscopy in a wide range of frequencies and
temperatures. The dielectric properties of composite
materials based on CdC8 matrix with semiconductor and
metallic nanoparticles are analyzed using 2 visualizing
methods (Nyquist and Bode plots). This allows us to analyze
separately the different components and processes that occur
in the system: polarization effects, electrode contact
resistances, liquid crystal volumes and others to evaluate
their contributions to the general behavior of the material.
Using impedance spectroscopy method, we evaluated the
material characteristics including ion mobility and rates of
relaxation processes. The results provide a fundamental
understanding of the behavior of nanocomposite materials and
have a great potential for the development of sensors and
optical devices.D. Zhulai greatly appreciates a research
grant from the German National Academy of Sciences
