A selectively reflective polymer moulded article and a process for producing the same |
摘要 |
<p>This invention provides, in an easy manner, a film-like moulded article which shows a selective reflection of a wavelength and circularly polarized light. A suitable environment for formation of a liquid crystalline phase is prepared by forming a moulded article (thin film-like moulded article) using a cellulose derivative which can form the liquid crystalline phase (e.g. a water-insoluble cellulose derivative such as ethyl cellulose), and allowing the moulded article to absorb a highly volatile organic solvent by contact with its vapour. After formation of the liquid crystalline phase, removal of the organic solvent provides the object moulded article. The thin film-like moulded article can be employed for an optical element of a circular polarized light-generator or a decoration material. <IMAGE></p> |
