The dispersion of nanomaterials in ferroelectric liquid crystals (FLC) has
turned out to be a promising method for fabricating optical memory devices and
tuneable electro-optical materials. In a nanosuspension between FLC and nanoparticles,
the presence of the dopant particles creates a synergic interaction with host FLC, which
leads to the improvement of electro-optical properties. Tailoring with nanoparticles of
suitable size, concentration, and compatibility results in various fascinating effects and
new multifaceted composites for electro-optical devices. Adding nano-sized materials
such as metallic, semiconducting, insulating or other functional species into the FLC
matrix is a fertile method, giving rise to or increases in memory retention and other
electro-optical properties that can replace the current electro-optical devices. These
advancements depend on the harmony between the guest and host materials. This
chapter gives a comprehensive overview of the present technologies and enhancements
that have been acquired in nanoparticle/FLC composite systems, especially for optical
memory devices and display applications.
