  • Patent number: 11281102
    Abstract: Provided is a fluorine-containing polymer which has no perfluoroalkyl group of 4 or more carbon atoms and which, when formed together with a photoacid generator into a film, shows water repellency after film formation, but becomes hydrophilic by the action of an acid generated under light irradiation, and thus serves as a pattern forming material capable of forming a film with high sensitivity and resolution. A fluorine-containing polymer according to the present invention has a repeating unit of the formula (1) where R1 is a hydrogen atom, a fluorine atom or a C1-C10 alkyl group; R2 to R5 are each independently a hydrogen atom or a C1-C10 alkyl group; X is a single bond or a divalent group; Y is a C1-C3 fluoroalkyl or carboxylate (—COOR) group; R is a C1-C3 fluoroalkyl group; and seven or less of hydrogen atoms contained in the substituent group may be substituted with fluorine.

  • 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.
