Abstract: Ink-jet printable compositions including nanoparticles capped with a protective layer of hydrocarbon chains and a single solvent exhibiting a single evaporation rate and having a specifically defined viscosity and surface tension that result in uniform and printable alignment layers for liquid crystal materials. Patterned liquid crystal-containing cells are also disclosed including one or more layers including the same or different nanoparticles capped with a protective layer of hydrocarbon chains printed on a surface of a substrate or even another nanoparticle-containing layer. Methods for producing the cells are also disclosed, including the step of printing a pattern on one or more portions of a cell surface utilizing a composition comprising the capped nanoparticles. Devices including the cells are also disclosed.
