The paper presents the results of experimental studies of the diffraction efficiency and selective properties (angular and polarization selectivity) of holographic inhomogeneous photonic structures formed in composite polymer-dispersed liquid crystals with different concentrations of the initial mixture components. Prepolymer mixture component composition was optimized in terms of the photonic structure diffraction efficiency maximum. The dependence of the samples diffraction and polarization characteristics on the external electric field value were obtained.
