摘要： Wrinkling of supported thin films is a strain-driven phenomenon that enables scalable and low-cost fabrication of periodic micro and nano scale structures. The morphology of wrinkles depends on both the magnitude and the nature of compressive strains that are applied to the thin film. This disclosure presents the methods to fabricate asymmetric 2-D wrinkled structures using biaxial compressive strains. The method relies on the dependence of wrinkle morphology on both strains and strain paths to generate asymmetric 2D wrinkles. Asymmetry is achieved by deliberately traversing the system through a strain state that creates cracks along a preferential direction. Fabricated patterns include non-uniform zigzag wrinkles that demonstrate period doubling only along one direction.

摘要： A method for manufacturing a stretched film, including stretching a long-length resin film in an oven by grippers while conveying the resin film to pass the resin film through the oven to manufacture a long-length stretched film having a slow axis within an average angle range of 10° or more and 80° or less with respect to a width direction thereof, wherein the oven has a stretching zone and a heat setting zone in this order from an upstream side, and the method includes the steps of: holding the both edges of the resin film by the grippers; stretching the resin film in the stretching zone; releasing the resin film from the grippers in the heat setting zone; and subjecting the resin film released from the grippers to a heat treatment at a temperature higher than Tg−10° C. and lower than Tg for 10 seconds or more in the heat setting zone.
