▎ 摘　　要

NOVELTY - Preparing black phosphorus-based nanocomposite material comprises (a) using black phosphorus as raw material, and layered material as friction agent, mixing and sealing raw material and friction agent in a ball mill jar with agate balls, and (b) transferring the ball mill jar containing the mixture in a common planetary ball mill for ball milling reaction, during the ball milling process, under the action of the friction agent, sliding the black phosphorus flakes to cause peeling, at the same time, the high-frequency impact generated by ball milling makes the black phosphorus and the friction agent form a firm bond to prepare a stable black phosphorus-based nanocomposite. USE - Preparation method of black phosphorus-based nano composite material is used in the fields of energy storage, biomedicine and so on. ADVANTAGE - The method realizes low-cost, high-efficiency and controllable preparation of black phosphorus-based nanocomposites using an ordinary planetary ball mill under the condition of adding friction agent.
