▎ 摘　　要

NOVELTY - Manufacturing (M1) a water-soluble transfer stack (5) comprising multiple two-dimensional material layers (2), comprising: (i) providing a growth stack comprising a growth substrate (3) and a two-dimensional material layer; (ii) applying an intercalating solution to the growth stack; (iii) applying a transfer layer comprising a water-soluble polymer film (1), to the growth stack; (iv) delaminating the water-soluble polymer film together with the two-dimensional material layer, thus obtaining a delaminated film (4) from the growth substrate; and (v) repeating the steps (i)-(iv) a number of times, where for each repetition the most recently obtained delaminated film is used as the transfer layer, thus manufacturing a water-soluble transfer stack comprising multiple two-dimensional material layers. USE - The method is useful for manufacturing a water-soluble transfer stack comprising multiple two-dimensional material layers which is used in photovoltaics, semiconductors, electrodes and water purification. ADVANTAGE - The method is simple and versatile. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) water-soluble transfer stack comprising multiple two-dimensional material layers manufactured by the method; (2) manufacturing (M2) multiple two-dimensional material layers on a target substrate, comprising (a) obtaining a water-soluble transfer stack comprising multilayer two-dimensional material, and (b) applying the transfer stack to the target substrate; and (3) multilayer two-dimensional material, comprising multiple layers of a two-dimensional material, where the average maximum height of roughness is below 50 nm. DESCRIPTION OF DRAWING(S) - The figure shows schematic outline of manufacturing a water-soluble transfer stack.
