NOVELTY - Adjustment of space between two-dimensional material layers, involves placing the material to be controlled in a chemical control agent for chemical reaction. The chemical control agent comprises 1 g persulfate, 4-8 mL concentrated sulfuric acid, and hydrogen peroxide. The volume ratio of concentrated sulfuric acid and hydrogen peroxide is 4:1-10:1. USE - Adjustment of space between two-dimensional material layers. ADVANTAGE - The method uses the gas pressure generated by the interlayer chemical reaction of the two-dimensional material corresponding to the two-dimensional material to counteract the interlayer Van der Waals force to realize the increase of interlayer distance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the chemical control agent.
