Abstract
The study investigates the influence of diamond nanoparticles (DNPs) on the electro-optical and dielectric properties of nematic liquid crystal (NLC) ZLI-2976. DNPs were dispersed in varying concentrations (0.1 wt%, 0.3 wt%, and 0.5 wt%) to explore their impact on key parameters such as threshold voltage, dielectric anisotropy, and response time. The results revealed that DNPs significantly reduce the threshold voltage by up to 22 %, particularly at higher concentrations, while enhancing dielectric anisotropy and optimizing response time. Polarizing optical microscopy (POM) confirmed uniform nanoparticle dispersion, and dielectric spectroscopy highlighted concentration-dependent permittivity variations, with DNP-NLC interactions dominating at lower concentrations and DNP-DNP interactions influencing higher concentrations. These findings demonstrate the potential of DNP-doped NLCs for advanced liquid crystal device applications, offering improved performance in terms of reduced operating voltage, enhanced electro-optical response, and optimized switching dynamics.
期刊介绍:
The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems.
Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal:
Low-dimensional systems
Exotic states of quantum electron matter including topological phases
Energy conversion and storage
Interfaces, nanoparticles and catalysts.
