Dielectric spectroscopy study on the impact of magnetic and nonmagnetic nanoparticles dispersion on ionic behavior in nematic liquid crystal

Autor: Habib Ayeb, Taoufik Soltani, Ahmed Mouhli, Tayssir Missaoui, Fathi Jomni

Publikováno v: Phase Transitions. 94:37-46

We investigated the impact of two types of nanoparticles, magnetic (γFe2O3) and nonmagnetic one (CeO2) dispersed in nematic 5CB matrix. Dielectric spectroscopy was used to investigate the dielectri...

In this article we show how spherical nanoparticles (NPs) imposing planar anchoring can strongly impact the viscoelastic, dielectric, and electro-optical properties of a nematic liquid crystal when they are not aggregated. We also demonstrate that wh

International audience; A long time ago, Brochard and de Gennes predicted the possibility of significantly decreasing the critical magnetic field of the Fredericksz transition (the magnetic Fredericksz threshold) in a mixture of nematic liquid crysta
