T
he molecular liquid crystal order locked in a polymer
network by photopolymerization brought a new dimension
to liquid crystal technology. Initially developed as low shrinkage,
low thermal stress coatings, RM’s soon demonstrated their
function for optical applications. The large, temperature-stable
and adjustable birefringence proved to be ultimately useful
for the display industry which adopted the RM’s for many
purposes, varying from viewing angle enhancement to optical-
retarder based 3D imaging optics. Presently, advanced optical
applications for augmented reality and astronomy lenses are

crystal effects for smart windows and dedicated display types.
The use of RM’s for non-display applications is studied by
many academic and industrial institutes. Typically, they are
polymers that change shape, surface structure or porosity.
At Eindhoven University, we developed self-sustaining
oscillators and micro-transport devices responding to
triggers as heat, light and/or electrical fields. Films may
deform from a flat to a complex, but pre-designed, shape
with prospects to light-triggered origami and self-folding
plastic elements. A completely new development relates
to coatings that switch their surfaces from basically flat to
corrugated with a controlled topography, thus controlling
properties as friction and grip. And coatings are developed
that can dynamically absorb or secret liquids. The lecture
will discuss our newest developments, giving a preliminary
view on the future of RM’s with advanced applications
in the fields of smart coatings, soft robotics and haptics.
