Liquid crystal micro-composites based on ferroelectric liquid crystal and a chiral photocrosslinkable liquid crystal polymer are studied. Their ferroelectric properties are closely connected to their polymerization process. The effect of the UV curing conditions on the ferroelectric behavior is discussed. Low UV intensity applied for a long time treatment leads to a polymer network that introduces little variations on the pure FLC behaviors.
