This paper presents a study of the properties of holographic gratings recorded by polarization holography in a thin layer of a polymer-liquid-crystal composite that consists of an acrylic monomer, an initiator, and a nematic liquid crystal. An experimental study is carried out of how the formation conditions and the ratio of the components that make up the prepolymer composite affect the diffraction efficiency of the holographic polarization gratings. The temperature and concentration ranges of the nematic liquid crystal are established at which the gratings with the greatest diffraction efficiency are formed. The dependence of the diffraction efficiency on the exposure energy is presented.
