Dispersions of Diamond Nanoparticles in Nematic Liquid Crystal/Polymer Materials
Diamond nanoparticles (DNP) were added in small quantities to low molecular weight liquid crystals (LC). These particles were also combined with monomers and cured monomer/LC mixtures to elaborate polymer-LC-NP dispersions. The influence of sample composition and irradiation conditions was studied by several experimental techniques and especially by the analysis of the electro-optical response, polarizing optical microscopy, and differential scanning calorimetry. Electro-optical characteristics of polymer-LC-NP dispersions exhibit lower transmittance values in the ON state and higher switching voltages compared to polymer/LC systems.
