Title:
NANOMATERIAL RIBBON PATTERNING METHOD AND NANOMATERIAL RIBBON PATTERN MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2019/132312
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a nanomaterial ribbon patterning method which can control the width, length, and spacing of a nanomaterial ribbon pattern, and a nanomaterial ribbon pattern manufactured thereby. The nanomaterial ribbon patterning method comprises the steps of: forming a first nanomaterial layer having a first threshold strain on the upper surface of a substrate; forming a second nanomaterial layer on the upper surface of the first nanomaterial layer; forming a thin layer having a second threshold strain smaller than the first threshold strain on the upper surface of the second nanomaterial layer; generating a plurality of cracks in the thin layer and the second nanomaterial layer by applying a tensile force to the substrate; forming a mask on the upper side of the thin layer and forming a sacrificial layer on the thin layer and portions of the cracks that are not masked by the mask; removing the mask and peeling off the sacrificial layer, the thin layer, and the second nanomaterial layer from the first nanomaterial layer by using an adhesive film; performing etching to leave only the sacrificial layer and the first nanomaterial layer; and removing the sacrificial layer to generate a nanomaterial ribbon pattern.
