Liquid crystalline assembly of nanocylinders

Controlled bottom-up assembly of nanocylinders (e.g., nanotubes, nanorods, nanowires) into large area aligned arrays is widely recognized as a key obstacle impeding application development. Processing of lyotropic liquid crystal phases is a promising route for overcoming this obstacle, but nanocylinder liquid crystalline science is a nascent field that tends to be fractionated based on material type. This review explores the common challenges and achievements of nanocylinder liquid crystal research by focusing on three types of systems: (i) carbon nanotubes, (ii) inorganic nanocylinders, and (iii) cellulose nanocrystals.
