Abstract: Since their development in the 80’s of last century, reactive mesogens (RM’s) form a versatile class of soft materials. The frozen-in molecular order of the polymers formed upon polymerization led to a wealth of new applications. Initially developed for use as low shrinkage, low thermal stress coatings, RM’s demonstrated their function especially in optics especially for displays. More recently it was found that triggered by heat, light or electricity the polymers change shape, surface structure or porosity. At Eindhoven University, we developed self-sustaining oscillators, cilia based micro-transport devices and haptic surfaces. A new development relates to coatings that switch their surfaces from flat to corrugated with a preset topography, enabling control over friction, grip, soil rejection and particle manipulation. The lecture will discuss the history and newest developments in responsive liquid crystal polymers, giving a preliminary view on the future of RM’s with advanced applications in the field of soft robotics.
