Zusammenfassung: | The invention discloses a polymer dispersed liquid crystal film and a preparation method thereof. The preparation method of the polymer dispersed liquid crystal film comprises the following steps: (1) uniformly mixing liquid crystal and a composition containing a polymer monomer to form a liquid crystal mixed solution which is isotropic at room temperature; (2) mixing the liquid crystal mixed solution with microbeads, clamping the mixture between two transparent conductive films, and rolling to form a liquid crystal film; and curing the liquid crystal film to obtain the polymer dispersed liquid crystal film. The microspheres are selected from polystyrene microspheres made of polystyrene as a material. Researches show that in the preparation process, the polymer dispersed liquid crystal film prepared from the polystyrene microspheres made of polystyrene has relatively low haze, and the haze is obviously smaller than that of polymer dispersed liquid crystal films prepared from microspheres made of other materia |
