Enhancing Liquid Crystal Properties

DOI

Liquid crystal displays are ubiquitous but they are not perfect. It is desirable to reduce the voltage required to switch a pixel from light to dark in order to reduce power consumption and extend the time between charging mobile devices. This could be achieved by doping a normal nematic phase with particles having strong electric dipoles, an idea first put forward by Brochard and de Gennes in 1970. Inorganic ferroelectric particles have not worked well, having a tendency to precipitate out of suspension and to lose their dipoles. This proposal represent an attempt to utilise the large dipole found in certain polypeptides. Our material has been modified to improve its solubility in nematics. The aim of the experiment is to determine whether it exists as a rod with a dipole in suspension and the degree to which it aggregates. This will be achieved by small angle neutron scattering.
