However, in the stirring and dispersing device of the scheme, the surface of the nano material is extremely easy to damage in the dispersing process, the energy consumption is relatively large, the effect is poor, and the laboratory requirement cannot be met. According to the ultrasonic dispersing device, a large amount of nano materials need to be dispersed once, the ultrasonic transmission distance is short, the nano materials far away from the ultrasonic wave need longer time to be dispersed, and the nano materials near to the ultrasonic transmission distance can be damaged due to long-time stress.
