An optically anisotropic film based on a two-phase polymeric material, and a method for the fabrication is provided. The two-phase polymeric material comprises a polymer matrix and a partially crystalline film of ordered, immobilized, organic molecules. The polymer matrix provides desired mechanical properties while the crystalline film provides desired optical properties of the fabricated material.

Two-phase polymeric materials and methods for making

Copolymers of MMA, n-butyl-, tert-butyl-, and n-decyl methacrylates with Brilliant Green styrenesulfonate and methacrylate were synthesized. The effect of alkyl substituents and copolymer composition on optical absorption spectra was studied. In the presence of ammonia, the copolymer films containing immobilizcd dye were shown to experience reversible decoloration. For the copolymers with different composition, diffusion coefficients of ammonia were calculated. In contrast to the copolymers, the absorption spectra of the composite films obtained by mechanical mixing of poly(alkyl methacrylates) with Brilliant Green oxalate appear to change with time under UV and visible light irradiation, and no complete recovery of their color upon ammonia desorption was observed
