Effect of magnetic nanoparticles with various geometrical shapes on morphology and dielectric properties of nanodispersions of nematic liquid crystal in polymer matrix
Prepared in this work are dispersions of nematic liquid crystal in polyvinyl
 alcohol with sizes of liquid phase inclusions less than one micrometer (nano-polymer
 dispersed liquid crystal (PDLC)) by changing technology of mixing the components. It
 was shown that, like to th...

| description | Prepared in this work are dispersions of nematic liquid crystal in polyvinyl
alcohol with sizes of liquid phase inclusions less than one micrometer (nano-polymer
dispersed liquid crystal (PDLC)) by changing technology of mixing the components. It
was shown that, like to the case of earlier examined dispersions with the droplet sizes 6
to 10 μm (micro-PDLC), the conductivity of nano-PDLC has two components: the ion
one, which value does not depend on frequency, and the electron one, the value of which
depends on frequency according to a power law. It was found that the ion conductivity of
nano-PDLC is three orders of magnitude higher than that for micro-PDLC, and the
exponent for the electron components of nano-PDLC conductivity is less than that for
micro-PDLC. It was shown that the spherical and rod-like magnetic nanoparticles (MNs)
influence in a different manner on the conductivity components of nano-PDLC. If for the
maximum concentration of spherical MNs 2 * 10⁻³ wt.% the ion conductivity is 2-fold
increased, then at the same concentration of rod-like MNs the ion conductivity value
increases by more than one order of magnitude
