Patent abstract

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.
