Compared with the ultrasonic-assisted method, shear mixing is a much more common and simple method, which only requires the stirring process and has the potential for industrial mass production [85]. In the process of stirring, the shear force generated by stirrer rotating is used to separate the aggregates of nanofillers. Due to the low strength of the shear force, the nanoparticles will be separated under stirring and then aggregated again, so it is generally necessary to increase the speed of the agitator to complete the separation. This method generally does not destroy the structure of nanofillers; therefore it is suitable not only for separating loosely bound nanoaggregates, but also for stripping off some layered nanosheets. In addition, this method needs to be carried out in low viscosity solvent just like ultrasonic assisted method.
