Cholesteric Liquid Crystals for Color Information Technology
TLDR
In this paper, the molecular ordering of cholesteric liquid crystals is addressed and applications in rewritable color recording are highlighted, where a sample recorded using a laser is shown.Abstract:
Fixation of the molecular ordering of cholesteric liquid crystals is essential for use of these materials in color information technology. Methods to achieve this as well as thermal and photochemical control of the cholesteric pitch of the liquid crystals are addressed and applications in rewritable color recording are highlighted. The Figure shows a sample recorded using a laser.read more
