摘要:
This invention provides liquid crystal compositions for light controlling materials of light scattering type having both memory and high speed response characteristics. The composition neither needs a temperature controlling device nor a device for imparting a shear stress as a memory erasing device, because the composition comprises a two-frequency addressing liquid crystal or such liquid crystal with an ionic component. The two-frequency addressing liquid crystal responds to an electric field and exhibits a positive dielectric anisotropy or a negative dielectric anisotropy depending on the frequency region of the electric field. Because the flat shaped particles of the present invention exhibit an affinity with the liquid crystal, the particles are dispersed in the liquid crystal and form liquid crystal domains effectively.

摘要:
A Polymer Electrolyte Membrane is formed by hot air drying of a membrane formed with an acidic main-polymer having proton conductivity and capability of forming an electrolyte membrane (S12), and then immersing it into a basic polymer solution to impregnate the membrane with the basic polymer (S14). The basic polymer is introduced in a large quantity into a site acting as a proton conduction pass of the main-polymer to take charge of the proton conduction. Since in the Polymer Electrolyte Membrane, a base polymer takes charge of proton conduction as compared with the case where proton takes charge of the proton conduction as a hydrate, the base polymer shows favorable proton conductivity even in a low humidity state at an elevated temperature exceeding boiling point of water.
