Title:
DEFORMATION METHOD FOR CROSSLINKABLE LIQUID-CRYSTAL POLYMER MATERIAL, AND OPTICALLY DRIVABLE COMPACT
Document Type and Number:
WIPO Patent Application WO/2013/176287
Kind Code:
A3
Abstract:
Provided is a technique for deforming a crosslinkable liquid-crystal polymer material containing photochromic molecules, without using the irradiation of ultraviolet-blue light, wherein ultra-short pulse light is irradiated on a crosslinkable liquid-crystal polymer material (12) containing photochromic molecules (101), and the crosslinkable liquid-crystal polymer material (12) is deformed as a result of isomerisation being induced due to two-photon absorption by the photochromic molecules (101).
