Color ultrathin PDLC (polymer dispersed liquid crystal) film and preparation method thereof

The invention discloses a color ultrathin PDLC (polymer dispersed liquid crystal) film and a preparation method thereof. The color ultrathin PDLC film comprises two transparent and conductive ITO film layers and a color polymer-liquid crystal mixed functional layer arranged between the two film layers, wherein each transparent and conductive ITO film layer is only 25-75 mu m thick; the color polymer-liquid crystal mixed functional layer is prepared from a polymer intermediate, liquid crystals, an accelerator and a color pigment. By means of the color ultrathin PDLC film, an ultrathin PDLC film for vehicles has better user experience, and the problems that the service life is shortened and the like due to overlarge thickness of a common vehicle-mounted PDLC film material is solved. The preparation method of the color ultrathin PDLC film is applicable to production of a production line with higher automation degree, reduced cost and higher production efficiency, so that mass production of the color ultrathin PD
