The invention discloses an optical composite film with ultra-high haze, high light transmittance and high strength and a preparation method thereof, and relates to the field of flexible optical materials. The optical composite film with ultra-high haze, high light transmittance and high strength is prepared by dipping high-porosity paper in a water-soluble polymer solution and removing the solvent; the water-soluble polymer solution in the water-soluble polymer solution The mass ratio of polymer to high-porosity paper is (0.43-3.82):1, and the high-porosity paper is filter paper or rice paper. The haze value of the optical composite film with high haze, high light transmittance and high strength is between 78.75 and 95.15%, the total light transmittance is up to 84.76%, and the tensile strength is up to 93.62 Mpa, which can be applied to flexible optics devices or LED lighting, etc. |
