▎ 摘　　要

NOVELTY - Multi-element two-dimensional composite material, comprises two-dimensional material, quantum dot material and zero-dimensional material. The structure of the zero-dimensional material is zero-dimensional nanoparticles, where average particle size of the zero-dimensional nanoparticles is denoted as x, and the value of x is less than or equal to 10-55 nm. USE - Used as multi-element two-dimensional composite material. ADVANTAGE - The composite material overcomes the defects of the existing two-dimensional solid lubricant structure of easy degradation, poor weather resistance and easy wear, and ensures synergistic compounding of multiple nano materials, so that the composite material has excellent lubricating performance and extremely low wear. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing multi-element two-dimensional composite material comprising (i) placing substrate on the bottom of the container, (ii) adding two-dimensional materials, quantum dot materials and zero-dimensional materials into the solvent separately and dispersing them uniformly, and (iii) covering two-dimensional material, quantum dot material and zero-dimensional material are on the surface of the substrate, taking out the substrate, and allowing to stand until the solvent evaporates completely to obtain multi-element two-dimensional composite material.
