iquid crystal polymer composites are the timely response

to the needs of a modern optical industry for low driving

voltage adaptive materials providing large phase retardation

(for UV, visible, and IR) within a sub-millisecond time frame.

We consider liquid crystals immersed into a nano-structured

sponge like polymer network. The network’s long chains impose

a desired alignment for liquid crystal molecules enabling the

creation of thick homogeneous liquid crystal slabs (up to 1mm,

in comparisonwith available today only 50microns thick aligned

liquid crystal layers). The properties of these materials are

enriched tremendously by adding various nanoparticles. For

example, mixing ferroelectric nanoparticles with a liquid crystal,

generates ultrahigh electric fields within the liquid crystal,

which combined with their small size, produces a uniquely

exciting and largely unexplored system of composite materials

which exhibit novel collective particle host interactions. These

interactions promise a variety of exotic electro-optic and other

applications. In this case, ferroelectric nanoparticles share

their high intrinsic sensitivity to electric fields with the entire

liquid crystal matrix. Therefore, doping the liquid crystal with

ferroelectric nanoparticles brings benefits of a lower driving

voltage and faster switching speed than in any liquid crystal

devices available today. As a result, we demonstrate the power

of nanotechnology toamplifybyordersofmagnitudethenatural

properties of liquid crystals by doping them with nanoparticles

and hosting them in a nano confining polymer matrix.
