▎ 摘　　要

NOVELTY - A two-dimensional nanomaterial comprises 1.1-1.4×10-3wt.% RGO solution, methyl methacrylate, azobisisobutyronitrile and phenanthrenequinone in mass ratio of 2:100:1:1-1.3. The particle size of RGO nanoparticles in the RGO solution is 15-30 μm. USE - The two-dimensional nanomaterial is useful for holographic storage technology. ADVANTAGE - The two-dimensional nanomaterial introduces RGO nanoparticles with specific particle size into the phenanthrenequinone/polymethylmethacrylate material, which can greatly improve the orthogonal polarization diffraction efficiency and photosensitivity of the performance of the holographic storage material. The RGO nanoparticles have ultra-high elastic modulus, large specific surface area, and excellent strength, thermal and electrical conductivity, optical performance, hydrophilicity and dispersibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the two-dimensional nanomaterial, which involves mixing the above-mentioned components, ultrasonically oscillating, stirring in a water bath, cooling, and baking.
