▎ 摘　　要

NOVELTY - Increasing reactivity of two-dimensional material (100) having a layered structure involves applying pressure to an end portion of a layer (110) of a two-dimensional material and an end portion of a layer (120) which is adjacent to the first layer such that the distance (d2) between the end portions of the layers (110) and (120) is more than the average interlayer distance (d1). USE - Increasing reactivity of two-dimensional material chosen from graphite, graphite oxide, hexagonal boron nitride and transition metal chalcogenide used in manufacture of graphene oxide (all claimed). Uses include but are not limited to secondary battery, fuel cell, filtration membrane, chemical detector, super capacitor and transparent electrode. ADVANTAGE - The method is economical, and increases reactivity of environmentally-friendly two-dimensional material, with high quality control in short time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene oxide, which involves placing graphene oxide in a Taylor-Couette reactor in which Taylor vortex is formed, applying pressure to end portion of the layers (110) and (120) such that the distance between the end portions of the layers is more than the average interlayer distance, and peeling off the graphene oxide. DESCRIPTION OF DRAWING(S) - The drawing shows a simplified view explaining the application of pressure to the two-dimensional material. Two-dimensional material (100) Layers (110,120) Distance (d1,d2)
