摘要:
A method of manufacturing an optically anisotropic polymer thin film includes forming a composite structure that includes a polymer thin film and a high Poisson's ratio polymer thin film disposed directly over the polymer thin film, attaching a clip array to opposing edges of the composite, the clip array including a plurality of first clips slidably disposed on a first track located proximate to a first edge of the composite and a plurality of second clips slidably disposed on a second track located proximate to a second edge of the composite, applying a positive in-plane strain to the composite along a transverse direction by increasing a distance between the first clips and the second clips, and decreasing an inter-clip spacing amongst the first clips and amongst the second clips along a machine direction, wherein the high Poisson's ratio polymer thin film applies a negative in-plane strain to the polymer thin film along the machine.
