Method Of Imprinting Texture On Rigid Substrate Using Flexible Stamp

Abstract: [0001] A method of imprinting a texture on a rigid substrate, having area greater than 50 square centimeters, preferably greater than 200 square centimeters, is provided. The texture imprinted on the rigid substrate facilitates light management through the rigid substrate. The method includes, wet coating a layer of a curable material on the rigid substrate. Thereafter, the method includes pressurizing a flexible stamp over the layer of curable material to imprint the texture. The flexible stamp includes a bottom zone having a texture profile corresponding to the texture. The bottom zone has Young"s Modulus between 0.5 MPa and 3000 MPa and enables tolerance for microscopic defects during imprinting of the texture. The flexible stamp also includes a top zone having Young"s Modulus between 0.1 GPa and 10 GPa. The top zone enables tolerance for macroscopic defects. Further, the method includes curing the layer of curable material. Finally, the method includes removing the flexible stamp,
