What are Glassy Liquid Crystals?
Glassy liquid crystals (GLC) are an advanced
form of liquid crystals that combine the properties
of conventional low-molar-mass liquid crystals with
the characteristics of polymers. As a new, unique type
of liquid crystals, GLC propel liquid crystal technology
to new levels, offering nearly perfect circular polarization
and selective wavelength reflection. The advantage of
GLC is that they can be processed like current liquid
crystals and then maintain their optical clarity and
molecular alignment when cooled into a solid, stable
film.
Uses for these high-performance liquid crystals
include flat screen displays, filters, optical storage, and other
electro-optic devices.
Specifications
GLC are novel glassy liquid crystals with elevated
phase transition temperatures, morphological stability and fatigue
resistance for photonic applications. When heated to Tg,
GLC undergo a second-order transition from mesomorphic solid
into liquid crystal without modifying the molecular order.
Applications include latching electro-optic
devices, thin film retarders and compensators, narrow
band polarizers, filters, and membranes.
