Description

technical field [0001] The invention relates to a device for preparing graphene composite particles. The device is used for preparing graphene composite particles and belongs to the technical field of graphene preparation. Background technique [0002] Electromagnetic pollution has been recognized as the fourth largest public hazard after air pollution, water pollution and noise pollution. The United Nations Conference on the Human Environment listed electromagnetic radiation as one of the major pollutants that must be controlled. According to foreign data, electromagnetic radiation has become one of the pathogenic sources that endanger human health today. Electromagnetic pollution refers to natural and artificial interference of various electromagnetic waves and harmful electromagnetic radiation. With the promotion and application of 5G technology, the power of radio frequency equipment will increase exponentially, and the electromagnetic radiation on the ground will incr...
