摘要： The present invention provides a solar reflective-absorptive device, comprising: an IR reflective transparent conductive film; a flexible transparent conductive film; a layer of liquid crystal dispersion in polymer matrix or polymer dispersion in liquid crystal domains allocated between said flexible IR reflective transparent conductive film and said flexible transparent conductive film. The liquid crystal dispersion is in polymer matrix or polymer dispersion domains, and comprises metalorganic dye compositions with absorption in the visible and/or IR regions of solar spectrum. The aforesaid liquid crystal dispersion consists of nematic mixtures and/or cholesteric mixtures comprising of chiral mesogenic or none-mesogenic chiral materials in nematic for IR absorption and/or broadband cholesteric materials for dynamic (electrically tunable) IR and visible absorption. The switching capability of the device will be carried out through reorientation of the liquid crystal dispersion sandwiched between said at least one transparent IR-reflective flexible conductive support and said transparent flexible conductive support.
