A method is described for preparing a nanorods assembly. The method comprises providing a mixture comprising at least a liquid crystal and nanorods and depositing said mixture on the surface of at least substrate. The method further comprises aligning said nanorods with their long axis of the nanorods along a preferred direction on said substrate resulting in a nanorods and liquid crystal assembly, said aligning being performed by applying an external alternating current electrical field.

Provided are methods of switching guest-host dual frequency liquid crystals by using a back flow. In the case of a shutter having a dual frequency liquid crystal layer between two transparent substrates, such a method includes: applying a first voltage having a first frequency to the dual frequency liquid crystal layer; and applying a second voltage having a second frequency to the dual frequency liquid crystal, the second frequency being higher than the first frequency, wherein the second voltage is higher than a threshold voltage that generates a back flow around liquid crystals of the dual frequency liquid crystal layer, and the first voltage is lower than the threshold voltage.

Disclosed is a filter for selective transmission of visible rays and infrared rays using an electrical signal. The filter comprises: a first filter for controlling the degree of absorption of visible rays by changing the molecular arrangement in accordance with the control of the electrical signal; and a second filter for controlling the degree of reflection of infrared rays by changing reflectivity in accordance with the control of the electrical signal.
