  • Patent number: 11168256
    Abstract: 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.
