A liquid crystal mixture and a temperature-responsive infrared reflection device made by using the liquid crystal mixture containing potassium laurate. Infrared light can pass through the device within a non-working temperature range, and a chiral dopant enables potassium laurate to form a cholesteric phase within a working temperature range. The birefringence value of the potassium laurate gradually increases with the increase of temperature between 12.5° C. and 26° C., so that the infrared reflection bandwidth of the device constantly increases. The birefringence value of the potassium laurate gradually decreases with the increase of temperature between 26° C. and 54.5° C., so that the infrared reflection bandwidth of the device constantly decreases. The infrared reflection bandwidth of the infrared reflection device can vary with temperature by adjusting the proportions of the ingredients of the liquid crystal mixture containing potassium laurate.

A self-aligning material, a self-aligning liquid crystal material, and a liquid crystal panel are provided. The self-aligning material is a nano-surfactant having a conductive material-philic end and a liquid crystal material-philic end, which can align liquid crystal molecules. Thus, it is unnecessary to dispose a polyimide alignment layer in the liquid crystal panel. As a result, the polyimide alignment layer and its manufacturing are saved, and production cost is reduced.

A non-linear side chain liquid crystal polyorganosiloxane differs from previous side chain liquid crystal polyorganosiloxanes. A method for preparing the non-linear side chain liquid crystal polyorganosiloxane involves hydrosilylation reaction of a SiH rich intermediate with an aliphatically unsaturated mesogenic compound. A liquid crystal composition containing the non-linear side chain liquid crystal polyorganosiloxane is useful in dynamic scattering mode electro-optic device for various applications.
